Suzuki Hayabusa

When Suzuki’s Hayabusa debuted in 1999, it inspired controversy for two aspects that would go on to become iconic: its controversial aerodynamic styling and its ability to open a giant can of whup-ass on anything else on the showroom floor.

After word got out about its 9-second abilities down the quarter-mile and its 190-plus-mph top speed, its “Eye-Abuse-Er” nickname became less prevalent. Soon the Busa was seen by some groups as the hottest thing on the street, and the mighty falcon became one of the primary canvases on which to polish frames and bolt on big-tire kits to up the bike’s badass-ness.

Now nine years on (and with a manufacturers’ agreement to limit top speeds to a laughably sedate 186 mph), the Busa was hit on the chin in 2006 by the Kawasaki ZX-14. The Kawi proved to be quicker and more powerful but also smoother and more comfortable. Regardless, the Busa remained as popular as ever and was unmatched for its street cred. Fearing a “New Coke”-type backlash, Suzuki engineers didn’t want to stray too far from the original Busa concept in this new redesign you see here. It’s still unmistakably a Hayabusa even if every fairing panel has been remolded. And it’s not much different underneath, either.

Your 9-second streetbike has arrived.

While it’s the new skin that first grabs your attention, it’s the unholy monster motor underneath that has earned the Hayabusa its veneration. Potent and durable, it has been the inspiration for a closer relationship with god among those who have twisted its throttle to the stop. For ’08, this legendary lump has received a 2mm longer stroke to yield 1340cc instead of the old bike’s 1299cc. New forged pistons are lighter and stronger and produce a 1.5-point increase in compression ratio to 12.5:1. Also forged is the crank, as it attaches to new chro-moly rods that are now shot-peened for added strength. Cam chain adjustment is now accomplished hydraulically, which also helps reduce mechanical noise.

Up top are 16 new titanium valves that save 14.1 grams on each intake and 11.7 grams on each exhaust for a significant weight loss in this critical area, allowing the replacement of double valve springs with lighter single springs. Valve sizes remain the same, but a new camshaft now forces greater lift on both the intake and exhaust poppets and has revised timing. It’s all fed by a pair of double-barreled 44mm throttle bodies. They use a version of Suzuki’s Dual Throttle Valve system that has a secondary throttle valve mounted above the primary that’s controlled by the bike’s electronic brain to maintain the ideal velocity of the intake charge based on rpm, throttle opening and gear position.

Controlled by a new high-powered Engine Control Unit, Suzuki says that the Busa has the company’s “most powerful, most advanced digital fuel-injection and engine management system.” Another important task of the ECU is controlling the different parameters of Suzuki’s Drive Mode System. Like the GSX-R1000 and ’08 Gixxer 600/750, the Busa has a handlebar-mounted switch to set the power mode into three available positions. It produces full power in mode A, the default setting, while mode B has a bit of the power edge clipped off. Mode C might be an asset in the rain, but it neuters all the excitement out of the muscular motor.

'Suzuki claims the new bike cranks out 194 horsepower at the crankshaft'

How muscular, you might ask? Suzuki claims the new bike cranks out 194 horsepower at the crankshaft, a 21-horse (12.1%) improvement. Torque is boosted 8.5% to 114 ft-lbs. The old 1299cc engine produced about 160 ponies at the rear wheel, so we expect this new one to spit out around 175 horsepower on a rear-wheel dyno.

“The new 2008 Haybusa is just so freakin’ fast it is unreal,” relates Neale Bayly from his experience at the press launch. “Accelerating off the corners with a quiet whoosh from the twin pipes like it had been shot out of a Howitzer, it feels like some sort of macabre video game flicking through some of Road America’s tighter sections. It starts making lots of power early, and by the time the needle is past five grand all hell is letting loose. It pulls without a break until the rev limiter kicks in with a bang somewhere around 11 grand.”

Suzuki claims a 21-horsepower increase in the new Busa, which should yield about 175 ponies at the rear wheel. Yee haa!

Although it shares no bodywork with the previous model, the ’08 Hayabusa remains as distinctive as ever.

Bayly also told us that the response from the high-tech fuel-injection system is flawless, aided by injectors with fine-atomizing 12-hole squirters instead of the previous four. “Giving superb throttle response from very low in the rev range all the way till the rev limiter kicked in, the system was faultless. One area that can cause problems with fuel-injection systems is at lower rpm on small throttle openings, but this was not the case with the big Suzuki.”

At the dragstrip, journalists struggled to break the 10-second barrier, but Jordan Motorsports Racer Aaron Yates was able to just nip into the 9-second bracket. We expect an epic duel between this uprated Busa and the more powerful 2008 ZX-14 for the honor of quarter-mile champ. Out on Road America, the new Busa handles a lot like the old Busa with extra power. This shouldn’t be much of a surprise considering that the bike’s twin-spar aluminum frame is nearly identical to previous, so we’ve got the same 23.4-degree rake and short 3.7 inches (93mm) of trail. A revised swingarm shortens the wheelbase a scant 5mm to 58.3 inches and features an additional strengthening rib for less flex.

“Don’t expect to go diving up the inside of any supersport bikes at a track day,” says Bayly, “but do perfect your passing wave as you cream them coming off the turns. Not that any of this should be surprising when you consider the bike weighs in around 500 pounds full of fuel, it is just a good idea to remind yourself of these facts before all that horsepower lets you get carried away.”

The old Busa’s most glaring shortcoming was the performance from its old-tech six-piston front brakes that were barely up to the task of slowing this earth-bound missile. We’re happy to report that Suzuki has now fitted up-to-date radial-mounted four-piston calipers to the magic Bus. They bite on 10mm-smaller 310mm discs that have a half-mil extra thickness (5.5mm) to handle the heat. Bayly tells us they are a major improvement.

Also aiding heavy braking is the new slipper clutch that Bayly says it quite effective. The clutch also has the Suzuki Clutch Assist System that increases the amount of force on the clutch plates without using stiffer clutch springs. The clutch also features a new friction material for better feedback at the engagement point. In addition, the width of a few transmission gearsets were revised and the upper three gears are sprayed with oil for reduced wear and quieter operation.

As for the Hayabusa’s new clothes, we’ll leave the aesthetic judgments to you. Aerodynamic efficiency, something the old Busa had over the more powerful ZX-14, is optimized with a wider fairing and a 15mm-taller windscreen to better shelter its rider. The body panel joints are now smoother and have no exposed fasteners, and the top of the fuel tank is lower to allow a tighter full tuck. The tailsection has an enlarged speed hump that will stir some commotion on the message boards, and it also sports integrated turnsignals that are said to “evoke a jet engine motif.” Front turn indicators are nestled into the edges of the air intakes in the nose.

Aesthetically speaking, the Busa’s new tailsection and mufflers are going to take some getting used to.

Does the new Hayabusa have what it takes to handle the newly upgraded Kawasaki ZX-14? We can’t wait to find out.

'The clutch also has the Suzuki Clutch Assist System that increases the amount of force on the clutch plates without using stiffer clutch springs.'

Also sure to be controversial is the Busa’s new exhaust system. The triangular muffler canisters on the 4-into 2-into-1-into-2 arrangement look ungainly but are a product of more stringent emissions standards. A catalytic converter is placed where the four head pipes meet under the engine.

“Listening to the sound of Aaron Yates and the new Suzuki Hayabusa going past a few feet from pit wall at close to 190 mph, I just couldn’t believe how quiet the bike was,” Bayly relates. “Almost knocking me off the wall, the sound of the windblast was actually louder than the exhaust.”

In the unrestricted environment of a racetrack, the burlier Busa doesn’t fail to thrill, allowing full use of its mega power. “With walls and fences everywhere, and the big fairing allowing me to get right under the airflow, the view across the clocks was surreal,” says Bayly. “The closeness of the walls greatly exaggerated the already intense speed, and every time you crank the throttle the track just seems to come at you in fast forward. The power is seamless and oh so abundant.”

So, depending on how you think about streetbikes, perhaps Suzuki’s claim of the new Hayabusa as “the ultimate sportbike for the road” has some merit. For some, it’s just too heavy and too powerful, but for others, this invigorated Busa is exactly what they’re looking for. We’ll give Bayly the last word.

“As the first significant overhaul to the all-conquering Japanese bird since 1999, the new 2008 Haybusa is everything the old one was and more. Faster, better handling, and with stronger brakes, the performance element is not going to disappoint. Looking sharper and more modern, without losing its distinct appearance, Busa lovers are not going to be unhappy either.

“And for the rebel without a clue, who thinks their V-Twin’s 67 horsepower and a set of loud pipes makes them a Bad Ass, well they are still going to hate the big, ugly lump of plastic as it goes by them at close to the speed of sound.”

Suzuki GSX650F

By Brad Puetz & 2WF.com, Jun. 20, 2008, Photography by Brad Puetz & 2WF.com

When I think of Suzuki motorcycles the first two models that instantly come to my mind are the GSX-R and SV-class motorcycles. Both are extremely capable and popular motorcycles in their respective classes, performing well on both the street and track. I have owned a healthy number of GSX-Rs and have spoken with many happy SV owners at many a track and local bike nights.

One motorcycle in the Suzuki line-up that never really gave me that warm fuzzy feeling, however, was the Katana. The Katana was Suzuki's answer for an inexpensive entry level motorcycle with sportbike looks and sport-touring comfort. While I am sure there are plenty of happy Katana owners out there, the somewhat alien-looking styling of the bike has always turned me off.

Well, for 2008 the Katana has received the axe to make room for the all new 2008 GSX650F. The new Suzuki is purpose built as a low-cost middleweight for the novice rider or the economical commuter looking for a comfortable ride with a sporty design. The GSX650F is based off the European Bandit 650 naked bike. It's an inline-Four with minimal upgrades from the Bandit such as full fairing, remapping for more revs and suspension which has been slightly tweaked.

A first glance of the blue and white GSX650F revealed the classic color combination and appearance of its close family relative, the GSX-R. It's no coincidence the front fairing shares a strong resemblance to the previous generation GSX-R600 and 750s. While it will not be mistaken for an exotic Italian bike, the GSX650F has clean sporty lines in a design that is a big improvement over the Katana models.

The GSX650F features an attractive and easy-to-read instrument cluster with tachometer, dual tripmeters, reserve tripmeter, clock, fuel gauge, and a useful gear-position indicator. Moving around on the Suzuki is easy with a roomy cockpit, comfortable one-piece seat with a low seat height and a well-positioned, rubber-mounted, tubular handlebar.

The GSX650F sports a liquid-cooled, fuel injected, 16-valve, DOHC 656cc engine utilizing a bore and stroke of 65.5 mm x 48.7 mm. The Suzuki Dual Throttle Valve fuel-injection system provides smooth acceleration. Four-hole injectors are used for optimum fuel atomization and greater power output. The cylinder head achieves a narrow included valve angle of 17 degrees for high intake and exhaust efficiency. Cam profiles are chosen with a priority on low-to-mid-range power output to deliver performance that is well suited to an entry-level street rider.

The Suzuki's full fairing design wrapped around a double cradle steel frame will have you thinking GSX-R thanks to the sport-oriented design. Geometry numbers are 26 degrees of rake and 4.25 inches of trail, with a 57.9-inch wheelbase. The fork is a 41mm Kayaba unit with adjustment for preload only. The rear shock comes equipped with adjustment for both rebound and preload. Heading out on the open road? The 5.0 gallon gas tank should allow you enough capacity to bust a few bugs before having to refill.

Taking the Suzuki out for its first excursion I was really looking forward to a day in the saddle that wasn't going to have me walking like a cripple when I returned with knees and back aching. The layout of the GSX650F suited me nicely with an easy reach to the bars and a relaxing bend at the knees. The riding position was well suited to both cruising and aggressive riding when the road gets a little twisted. Wind protection was decent and there was a good deal of room to tuck in if needed.

'The GSX650F motor has all the necessary ingredients to deliver an entertaining ride...'

The GSX650F fires up easily and runs smooth without unnecessary vibration. Spin the flexible motor up and it does a great job of putting the power down where you will likely be spending most of your time, in the low- and mid-range. Chasing through traffic full of stop signs and motorists, I really came to enjoy the motor which was well-suited to this type of riding. The short first gear on the GSX650F was a nice change from the supersport bikes which come equipped with gearing more suited for the track than stop-and-go traffic. Just dump the clutch and start clicking through the 6-speed transmission without worry, the GSX650F surges forward without a hiccup. An effortless clutch pull and smooth-shifting transmission made city traffic a breeze. With no under-tail exhaust or excessive engine heat pouring out at the legs, the Suzuki was quite bearable if traffic came to a stop for any amount of time.

There is no berserk rush to the power delivery but it won't put you to sleep either. Redline is at 12,500 rpm but it likes to be run in the 4,000-8,000 rpm range where it sings nicely in the power curve. The GSX650F motor has all the necessary ingredients to deliver an entertaining ride to anyone in the market for an inexpensive sporty ride in the middleweight class. If you are in the mood for utter madness, however, this motor will probably not suit your primal likings as the Suzuki pumps out the ponies in a pretty civilized manner.

Overall handling on the Suzuki was quite balanced and agile. It turns in well, sticks to a line, and can be gassed hard out of a turn. While not being the most sophisticated chassis, the GSX650F isn't going to do anything to get you in trouble. That is, of course, if you don't push it far beyond its limits.

I tried to do just that to see where its breaking point was. I saw my opportunity in the form of two rapidly approaching GSX-R1000s in my mirror with some young aggressive riders at the controls. What better way to see how the GSX650F would fare against some much more advanced hardware. As I let the young bucks come by, they took a quick glance, surely with fear in their eyes as they observed my proper upright riding position and the very intimidating backpack carrying my camera. I decided to tag along the rear as we hit a twisty section of road. As it turned out, the little Suzuki didn't fair too bad, staying right with my two test subjects quite easily until we hit some open road where the bigger bikes could flex their muscle. Soon I was a mere speck in the mirror as Suzuki's natural pecking order took over and the GSX650F was shuffled to the back.

'Overall handling on the Suzuki was quite balanced and agile. It turns in well, sticks to a line, and can be gassed hard out of a turn.'

The GSX650F is quite composed, and its 475-pound claimed dry weight transitioned nicely at a moderate pace. The wide handlebar does a good job of giving you the proper leverage to position the bike into the apex. While it is quite balanced and agile, it might not be your favorite track-day weapon. At more serious speeds while pushing the bike, the front end seemed to have a touch more trouble staying composed, becoming quite uneasy and a little on the springy side. The rear seemed to be doing a good job keeping the back end in line, but I was easily able to find the limits of the front fork with a good amount of flex and some quivering at the bars. You could tie the GSX650F into a bit of a knot if you really wanted to get aggressive with transitions, throwing the bike hard on it's side or really doing some late braking.

Speaking of brakes, while not the strongest I've ever put my hands on, they do have good feel and more than capable stopping power. The GSX650F comes equipped with Tokico 4-piston front brake calipers and 310mm brake rotors combined with a lightweight single-piston rear caliper and a 240mm rear brake disc.

Keeping the rubber side down were Bridgestone Battlax BT-011s up front and BT-020s in the rear, with a 120/70 ZR17 and 160/60 ZR17 front/rear tire combo. These tires worked excellent in many different conditions. My two weeks with the bike were filled with a generous amount of wet-weather riding on the GSX650F, and the Bridgestones gave me good confidence in the rain, enough to ride a few wheelies in a slight drizzle for some photo opportunities. In the dry conditions they were equally up to par, providing good traction both front and rear.

I have found that some people tend to think that because I race motorcycles I am a total speed-crazed adrenaline junkie always looking to run off with the neighbor's daughter. While the latter may be true and it may not be a bad idea to keep the daughters locked up, I actually do enjoy a restrained leisurely ride on a motorcycle that is composed at street speeds and not excruciating on the body. In fact I found that the GSX650F was really starting to grow on me over the two weeks. Constant commuting in the rain had me quite happy that I was riding a motorcycle with a mild temperament and a chassis I could trust.

While the limits of the GSX650F's capabilities can be reached quite easily by an experienced rider, I was not turned off by the Suzuki. Instead, I grew to appreciate the many qualities the GSX650F possesses. This is no one-trick pony. In fact it's an extremely versatile motorcycle. Whether you are into sport riding, touring or everyday commuting, the GSX650F has the ability to do it all. At an MSRP of $6.999 this will surely be an attractive option for the budget-conscious rider or someone looking for that first bike that gets it all started.

Harley-Davidson Electra Glide Standard

By George “Longride” Obradovich, Aug. 29, 2008, Photography by George “Longride” Obradovich


With the Sturgis Rally now over and done with, I can settle in and report on the Flame Blue Pearl 2009 Harley-Davidson Electra-Glide Standard that carried me there and back again. Many bikes that are tested by magazines are ridden a few times over a few miles, but this bike was ridden over 2500 miles and 9 days, so I didn’t just test this one, I lived with it. When you spend that much time on a bike the good, bad, and ugly really stand out.

The Electra-Glide Standard is a base model for the touring lineup. As such, with a beginning MSRP of $16,999 it and the Road King are the lowest priced FL models.

Let’s get the technical items listed first. As we now know from the press launch reports on the 2009 OE and CVO models, the entire touring line received an all-new chassis for better stability and handling.

Also standard on all ’09 touring models is EITMS, or Engine Idle Temperature Management System. The previous years for the 96-inch motor had a rash of complaints about rear cylinder heat roasting legs in hot climates, so Harley addressed the problem with the EITMS system.This bit of Harley tech stops fueling to the rear cylinder when engine temperatures get too high during idle; it’s also now rider activated or deactivated by rotating the throttle grip forward for a count of five seconds.

Lots of changes, same Harley style.

Lots of changes, same Harley style.

In further efforts to alleviate heat issues, the crossover pipe of the exhaust system was rerouted, now running beneath the engine instead of under the rider‘s legs for better heat reduction. The front suspension received new spring rates to complement the new chassis and the new multi-compound Multi-Tread tire from Dunlop. Additionally, the “Isolated Drive System,” or more commonly, cush drive, now has its housing molded into the rear wheel hub.

Standard features include the 96 Cubic Inch Twin-Cam motor, throttle-by-wire, 6-gallon gas tank, six-speed overdrive transmission, Brembo brakes, and beautiful 28-spoke cast wheels. Options include ABS brakes, a security system, and electronic cruise control. So that’s quite a list of features, old and new. Is all this technology really that great? How do all the new changes work, you ask? Read on.

Since I have a 2001 Electra-Glide, I can fully appreciate the changes made to the new ‘09 touring models. At first glance, the new bike doesn’t look all that different from my ‘01, but a trained eye sees the larger fuel tank shape and different exhaust routing. A couple of Florida-based bikers noticed I was riding a 2009 model at Sturgis; they looked it over with a tiny gleam of envy in their eyes.

The first chance I got to ride the bike was from Milwaukee to Chicago in the typical Midwest August heat – 92 degrees. Getting caught in a traffic jam on the way home, I can tell you that the EITMS system combined with the new exhaust routing works well. I felt almost no heat on my thighs where even my ‘01 would have been roasting them a bit on this day. And the system is so seamless; you wouldn’t even know it was there. No muss, no fuss.

The Twin-cam lump pulls smoothly from idle to redline. No injection glitches or surging could be felt anywhere in the powerband. The electronic cruise control makes this bike an absolute pleasure while hauling down the highway. I can’t say enough good things about having cruise-control on this bike. It was easily my all-time favorite feature. It is so nice to be able to set your speed on the highway and sit back and enjoy the view without hand cramps or worrying about speeding tickets.

This new bike doesn’t suffer the same buffeting that previous models endured from crosswinds or the turbulence generated by tractor/trailers or larger vehicles. The instability or “wobble,” that can be encountered in such windy conditions (especially on prior year models with their bat-wing fairing) seemed non-existent with this model.

Getting the 1000 miles to Sturgis and the 1000 back was really nice on this Electra-Glide, but I had a couple of nits to pick. I found the six-speed transmission to be loud and obnoxious at times. It went into gear with a loud clack and each gear whines a different tune. I could tell which gear I was in by the sound it made. Fifth gear is especially offensive with a whine loud enough to make me think something was wrong. Maybe because the rest of the package is so quiet the gear noise seems so noticeable. (I had a similar experience to Longride’s during my time on the new touring rigs at the ’09 model launch. It’s worth noting, however, that noises not normally noticed on other or similar bikes tend to be amplified as they bounce around the cockpit of bikes with such large fairings and/or bodywork. Locating the source of a noise can be like chasing a phantom. –P.B.)

Also of note, I had a small issue with the “new and improved” suspension. The highway ride was compromised by the stiffness of the suspension. Now, I am no lightweight at 250 lbs, but for even me to think the suspension was too stiff is a first for me. Usually I mash motorcycle suspension into mush on most bikes; I think Harley went a little too heavy on this one. Not that the bike is uncomfortable, but sharp highway jolts will jar you pretty good. Since H-D is emphasizing the handling on their new tourers, I think they designed this one more for corners than the highway. Corners on a Harley? Are you kidding?

Classic and functional cockpit. Sixth-gear indicator light is nice.

Yes, folks, this one handles. It is yards better than my ’01 and certainly the best handling Harley tourer ever. After taking this on a couple of spirited rides in the Black Hills, I can say that new chassis works. Iron Mountain Road in the Black Hills has everything from fast sweepers to 15-mph switchbacks, and is a real nice road to test the handling of any motorcycle. That stiff suspension makes sense when attacking the corners, and although the turn in seems a bit slower and heavier than the older bikes, once you get it heeled over, you are rewarded with dead solid handling and better ground clearance to boot. Corner speeds that would have my ’01 Glide doing the wobbly can be taken with ease on ’09 touring chassis. It is so well composed compared to the older generation frame that the difference is very noticeable. Add in the excellent Brembo brakes, which can haul the bike down from speed with two fingers, and you have a package that will eat those highway miles in comfort and can give you some excitement when the road gets twisty.

This bike came equipped with ABS for that extra margin of safety. For me, the jury is still out on ABS on motorcycles. I tested the ABS on this bike by purposely locking the front and rear wheels and you can feel the heavy pulsing as the ABS activates. I really didn’t like the feedback, and I guess I don’t want to rely on technology to save me from taking the time to learn proper braking technique in the first place. I guess for most, this is a good option to get on a bike, but being the old, stubborn guy I am, I just can’t see myself with an ABS bike. At least it is optional on the touring line. (ABS is standard on all CVO FL models. –P.B.)

As far as the ergonomics on this bike, it is still just like the Electra-Glides of old. The tank is noticeably bigger, but the bars, floorboards, and seat seem about the same. The stock seat is comfortable. I did two days of 600-plus miles, and I wasn’t too sore at the end. The new six-gallon tank gives Iron Butt types some extended range. Gas mileage varied from the high 30s on a fast highway blast into a headwind, to the high 40s on a normal highway cruise. The six-speed transmission really helps on those high-speed highway runs. At 80 mph, the motor is only turning about 3000 rpm. Nice and relaxed. Set the cruise and kick back. This one can eat the miles quickly, if desired.

The only drawback here is acceleration in overdrive is pokey at best. Expect to click down one gear for decent passing speed. One other feature that I didn’t talk about was the increased load capacity of the hard bags. Each bag is now rated to carry 5 pounds more than before, so you can get to your destination with more stuff. This is a really nice feature for us pack rats.

So are the new changes worth it? Does the new technology on the 2009 Harley-Davidson Electra-Glide Standard make a better motorcycle? Absolutely; but as you can tell from the article, some of the changes have some drawbacks. For example, the suspension that was great on the twisty roads was not as good on the highway. ABS is still a nice option for those that want it. It could save your bacon, but I just can’t bring myself to love it. My favorite extra is the optional cruise control.

The six-speed transmission is fantastic on the highway, but whines around town, and acceleration while in overdrive is less than stellar. The new chassis is 100% better that the old one. It gives a more stable highway ride and is rock solid in the corners. The EITMS system and changed exhaust routing took care of any annoying heat issues without any drawbacks. The engine ran perfectly, didn’t leak a drop of oil, and didn’t use any oil over the 2500 miles either. Nothing came loose, fell off, or didn’t function as intended. Fit and finish is top notch, and the Flame Blue Pearl paint is perfect. This is typical Harley-Davidson quality.

Puttin’ a smile on my face!

Puttin’ a smile on my face!

I guess the conclusion is that the bike just plain works! And although the tank and exhaust look a bit different, the bike still has “the look and sound” that has drawn people to Harley-Davidson motorcycles for oh-so-many years. Before riding this bike I was thinking of getting a new 2009 Electra-Glide. After riding this bike, I’m going to have to do more than think about it.

Star V-Max

By Kevin Duke, Aug. 26, 2008, Photography by Nelson & Riles, Alfonse Palaima, Video by Fonzie

The word icon is described as an important and enduring symbol. For Yamaha and Star Motorcycles, the VMax stands near the top of its bikes eligible for icon status. First seen in 1985 and barely revised since, this all-new VMax has gone through a decade-long gestation, with development work going back to 1997. The first running prototype was judged to be too big and the power too linear.

The 2009 Star Motorcycles VMax - an icon reinvented.

The 2009 Star Motorcycles VMax - an icon reinvented.

Now sold under Yamaha's Star Motorcycles banner, engineers grappled with the concept of a rebirth of a legend. Star is positioning the new VMax at the edge of the expressive/aggressive personality of the modern cruiser category. As such, they use terms like hot rod, muscle, power and respect to describe what the VMax represents.

To make sure Star was hitting its target audience, they conducted extensive market research with focus groups. Owners of the previous generation (which have an average age of 45-plus years) insisted a new version should have improved handling, increased power, a better riding position and continued use of shaft drive. And they were adamant for Star to use a V-Four engine and "keep the V Boost!"

A larger, more powerful engine was always going to be necessary, especially after the arrival last year of the Hayabusa-powered Suzuki B-King. An all-new V-Four (see sidebar below) was created, achieving Star's goal of reaching the 200-horsepower mark.

Bringing the VMax into the 21st century required enormous improvements to the flexi-flyer steel chassis of the old bike, so they threw it out and created an aluminum frame that uses the imposing engine as a stressed member for added rigidity. But getting a long, shaft-driven chassis to handle up to Yamaha's standards proved to be the most challenging aspect of the new bike, causing a delay to the bike's introduction until they got it right.

The production version of the chassis consists of a cast-aluminum perimeter-style frame and new alloy swingarm. The subframe is made from Controlled-Fill cast-aluminum sections and extruded-aluminum. The chassis' geometry is closer to cruiser specs than sportbike numbers, with a 31.0-degree rake, 148mm of trail, and a 66.9-inch wheelbase. The previous model had sportier geometry: 29.0 degrees, 119mm, and 62.6 inches, respectively. This latest Max is about an inch wider and 3.7 inches longer overall.

It all adds up to a machine with immense visual punch. The VMax's crowning accents are the aluminum air intake scoops that are now functional. The scoops are hand-polished to a fine luster (taking 40 minutes each!) then are clear-coated for an enduring shine.

What appears to be a fuel tank is really just a cover for the non-pressurized airbox and a place to mount a digital info panel that includes a clock, dual tripmeters, fuel gauge, gear indicator, coolant temp, mpg, intake air temp, throttle angle, stopwatch and a countdown indicator. Its electro-luminescence display is said to be clearer and faster than LCD. While the info panel is placed too low to be easily seen while riding, the giant muscle-car-like tachometer is in full view and is augmented by a shift light placed prominently alongside.

Upon firing, the VMax settles into a steady but menacing rumble. The V-Four, with its contra-rotating balance shaft, is quite smooth, but a rider never forgets there is something substantial reciprocating between the knees. A blip of the throttle reveals a fairly heavy flywheel effect, as revs don't soar as quickly as smaller, sport-oriented engines.

When building a replacement motor for an icon like the VMax, Yamaha/Star engineers knew they had to recreate a legend. While the old 1198cc V-Four was the bees' knees in 1985, it would take a large injection of power to be king of the hill in 2009.

The mantra of the muscle-car era was "there's no replacement for displacement," and the new VMax hums the same tune. While its 66mm stroke was retained, the '09 Max gets a big-bore treatment by enlarging its cylinders from 76mm to 90mm. This yields an engine with 481cc extra, a 40.2% bump to 1679cc.

Like the upcoming Aprilia V-Four Superbike engine, the VMax uses a chain to drive the intake cams, and from there a gear-set turns the exhaust cams, keeping the engine as short as possible. Valve-adjustment intervals are only every 26K miles. Star also tightened up the 70-degree vee cylinder angle to 65 degrees, also the same as the Aprilia mill. Combined, this tightened up the distance between the cylinder heads by a little more than 1 inch, and the monster motor is 7mm shorter overall.

Much of this new engine uses technology seen on Yamaha's top-line sportbikes. A Mikuni fuel-injection system uses a quartet of 48mm throttle bodies with 12-hole injectors, and it's operated by Yamaha's ride-by-wire Chip-Controlled Throttle (YCC-T). The three-processor ECU measures parameters (wheel speed, crank position, temperature, etc) every 1/1000th of a second. Interestingly, a Star-supplied chart says YCC-T also takes into account a lean-angle sensor, which, along with the standard ABS's wheel-speed sensors, could be deployed as a traction-control system. A look at our tire-melting video shows this not to be the case.

Also borrowed from Team Blue's R-series sportbikes are variable-length intake stacks (YCC-I) that use 150mm snorkels for strong torque at low revs. At 6650 rpm, the trumpets raise up to reveal shortie 54mm intakes for a V-Boost-like top-end hit that voraciously rockets the bike quickly through the gears.

Inside the motor are more sportbike-derivative pieces. Pistons are made from lightweight forged aluminum, and they rise and fall on the 180-degree crank inside ceramic-composite cylinder linings. The connecting rods are fracture-split and carburized for strength. The new combustion chamber is much flatter (a 29-degree included valve angle) and nets an 11.3:1 compression ratio which requires premium fuel. Magnesium engine covers try to keep weight down as much as possible.

Spent fuel exits into four header pipes that join in a large under-swingarm collector before flowing into a pair of four-exit mufflers with titanium skins. Inside are an oxygen sensor, two catalyzers, and an EXUP power valve.

What it all adds up to is a colossal 197 crankshaft horsepower at 9000 rpm. The final version of the previous VMax (last sold in '07) was rated at a paltry 133 hp at 8000 rpm, a whopping 48.0% less. Prodigious, too, is the new Max's torque production. Its 122 ft-lbs at 6500 revs dwarfs the 86.8 ft-lbs at 6000 rpm of the old bike to the tune of 40.6%.

There is so much power on tap that a Star rep related a story of how its rear tire was slipping on a rear-wheel dyno drum when testing its max power. Even adding a passenger didn't completely stop the slipping! I didn't manage to get him to reveal what numbers came up on Yamaha's Dynojet, but reading between the lines, we expect rear-wheel dyno figures approaching 180 hp. Note that Suzuki's B-King pumps out about 160 horses at the back wheel.

The VMax's tank-mounted info panel has a display that shows how much throttle is being used, but that's the last place you'll want to be looking if the throttle is cracked more than a quarter turn. Despite being muted by a substantial 684 lbs full of fluids, 200 ponies have a way of bringing the future quickly into the present. Serious thrust is available at just 2500 rpm, and it just keeps building exponentially from there to the 9500-rpm rev limit, accompanied by an impressive and distinct V-Four yowl. The outrageous powerband is linear but explosive, so much so that the midrange opening of the YCC-I is barely perceptible - acceleration changes only from "holy s*%t! to "Hello, God!"

The VMax is fitted with a drive system that helps and hurts. Hydraulic clutch actuation eases lever effort, and gearbox throws in the 5-speed tranny are short and precise. A race-style slipper clutch works okay, but it seems a bit incongruous to be doing high-rpm downshifts on a so-called cruiser. However, this is no ordinary cruiser and, in fact, might better be labeled something like a muscle naked. Star's Warrior is correctly termed a power cruiser, and the VMax is certainly something quite different.

The VMax's rear wheel is driven by a shaft, creating some suspension issues but enhancing its tire-smoking corner-exit abilities.

While the gearbox is first-rate, the shaft-drive system partially falls on the negative side of the ledger. Focus groups may have insisted on a shaftie, but this arrangement has its dynamic compromises, no matter how well it's designed. It's heavier, so a rear suspension can't react as quick, and it also makes the bike suffer a jacking effect that results in a stiffer and higher rear end when under power.

Meet the new burnout king.

The jacking effect is actually quite minimal on the VMax, so kudos there, but there's no getting around the stiffer rear suspension with the throttle twisted. Bump absorption isn't as compliant and, worse, the minimal weight transfer makes this the most difficult 200-horse bike to wheelie that I've sampled! Long black darkies are typically the result of mono-wheel attempts - taller, heavier riders, who induce more weight transfer, have an easier time of it.

However, this shaft-drive byproduct has hooligan benefits of its own. Without much rearward weight transfer, the reasonably sticky 200mm Bridgestone BT028 has a snowball's chance in hell of not melting when the V-Four is given its head. If you've even been foolish enough to want to mimic the rear-wheel-sliding corner exits of pre-traction-control GP riders, the VMax stands head and shoulders above anything else on two wheels. Tire-spinning corners exits have been part of my fantasy world that rarely transfer into actuality, but Mr. Max makes them ear-to-ear-grinningly real.

In regard to the bike's ultimate acceleration, the VMax is absent a probable electronic trick and equipped with an unexpected one. First, we're thrilled to report the ECU doesn't limit power in the lower gears like on many other modern hyperbikes. Electronic intervention comes into play once 220 kph (136.7 mph) is reached, as this is the Max's top-speed limiter. However, to not handcuff dragstrip performance, the limiter is lifted to a 230-kph (142.9 mph) threshold when a quarter-mile acceleration run is sensed! For what it's worth, I saw 145 mph on the speedo before I ran out of open road.

When it comes time to shed speed, the new VMax is worlds apart from the wimpy brakes of its forbear. Up front, a four-position lever actuates a Brembo radial-pump master cylinder that feeds a pair of 6-piston radial calipers biting on 320mm wave-type discs. They proved to be very powerful but not overly sharp. A Brembo rear master cylinder powerfully fires a single-pot caliper and 298mm wave rotor, and it was when using the rear brake that I was grateful for the bike's standard ABS which isn't intrusive.

In terms of real-world usability, the VMax performs better than expected, although it's a bit clumsy at lower speeds. The narrow handlebar and cramped riding position of the old bike has been opened up by moving the grip position an inch further forward and about a half-inch taller. The seat height is listed at a modest 30.5 inches, but its broad seating area gives narrow-hipped people like me a bit of struggle to reach the ground firmly with both feet. A stepped seat-back isn't just for comfort; it's also to keep you aboard the bike during 1G acceleration.

Dressed to the Nines

Star understands better than most Japanese OEMs that personalizing a motorcycle can be an integral part of the ownership experience. As such, it offers an extensive line of accessories for the new VMax.

Few materials are as emblematic of contemporary speed and racing as is lightweight carbon fiber, and Star delivers with an assortment of lovely composite pieces manufactured in-house. Tasty carbon bits include fenders, tank covers, seat cowls and side covers, but the beautifully made stuff isn't cheap. A set of the C-F air intake scoops costs a whopping $999.95.

Functional components include a flyscreen, touring windshield, hard saddlebags and a passenger backrest. An optional tail pack can attach to the passenger seat or an accessory aluminum luggage rack. Upping the bling factor is as easy as bolting on some billet aluminum covers for the cams, master cylinders and swingarm pivot.

The VMax's riding position is open and comfortable for rides longer than a quarter-mile.

The VMax's riding position is open and comfortable for rides longer than a quarter-mile.

Underneath the seat is 3.96-gallon fuel tank, same as the old bike, which helps lower the bike's CG. The VMax manages decent heat control through its dual radiators that keep its frontal area as slim as possible. Out of Ramona, stuck in traffic, I could feel a little heat on my ankles and shins, but not bad considering the engine's enormous output.

There are decent views out of the bar-mount mirrors for keeping an eye on your tail during your inevitable extra-legal antics. Freeway cruising is very comfortable for a naked, as a rider is sitting down in the bike, making even a 90-mph lope (with its overdriven fifth gear) quite bearable. A 2-year warranty adds peace of mind.

Star should be commended for the suspension it fitted to the Max. Both ends are produced by Soqi, a Yamaha subsidiary, and both the 52mm fork and single shock are adjustable for spring preload and both compression and rebound damping. But their best feature is tools-free knurled knobs to easily dial in optimum rebound damping at both ends, plus rear compression damping; a screwdriver needs to be unsheathed only for front compression. The rear end also has a handy hydraulic preload adjuster on the bike's left side that can be altered on the fly if you're flexible - otherwise, do it easily at a stop.

Although there are better bikes for cutting up the twisties, the VMax acquits itself well for a machine of its size.

Who wants to rumble?

Who wants to rumble?

The suspension is good stuff, but it is faced with the formidable task of controlling a hefty machine and its shaft-drive dynamics. Action from the titanium-oxide-coated fork legs is quite good, even with substantially increased spring rates. But the rear end often struggles with isolating bumps, faced as it is with the shaft-drive compromises. Backing off rear preload and compression damping soothed things somewhat, but it never responded like an optimized chain- or belt-driven bike.

More successful is the new VMax's handling qualities, one of the old bike's weakest aspects. Now with the new aluminum chassis, a beefy fork and a forged-aluminum lower triple clamp and a cast-aluminum upper, the big Star is ready to intimidate lesser riders on pure sportbikes down a canyon road.

Although it makes a Suzuki SV650 feel like a mountain bike in comparison, its handling is better than expected, with a chassis that feels stiff and responsive in steering transitions and a fork that offers decent front-end feel. You don't have to be a racetrack refugee to drag pegs on the VMax, but available lean angle is actually very respectable for a beast like this.

Any handling deficiencies it has are related to throttle response and the shaft drive. The YCC-T is endowed with a program to reduce engine braking feel by letting a bit of fuel seep through on trailing throttle, and this works seamlessly most of the time. But in some instances, the compression-braking effect is quite pronounced and, worse, unpredictable when it happens. Chopping the throttle mid-corner can unsettle the chassis, and a rider can feel some drivetrain lash with an uncertain throttle hand in corners.

The 2009 VMax - like nothing else.

The 2009 VMax - like nothing else.


When I first heard about the new VMax, I had two thoughts: First, it was about damn time! Second, hanging a $17,990 price tag on a Japanese bike can be akin to wearing cement shoes. But while I still wonder how well second- and third-year models will sell, I do see a lot of value in this scintillating machine.

Recreating an icon is never easy, but that's exactly what Star and Yamaha have done with the 2009 VMax. It has a few flaws and limitations, but its overall persona extends the Max's icon status. It's as distinctive as bikes come, it has terrific attention to detail, and it offers a thrill ride that can't be equaled by anything else on two wheels.

Just 2500 units (with commemorative badges) will be available for the 2009 model year, and more than half are already sold. You only have until October 31 to get your order in on the '09 VMax. Those who ordered early should see their bikes by the first part of November.

Ducati Desmosedici RR

By Kevin Duke, Aug. 07, 2008, Photography by Alfonse “Fonzie” Palaima, Video by Fonzie

It doesn’t take long to be intimidated by the outrageous Desmosedici RR. If the stratospheric $72.5K price tag doesn’t get you, the menacing mechanical cacophony upon start-up will. Observers are sucker-punched straight into the gut, and the beautiful racket portends an experience unlike any production streetbike in the world.

It’s quite incredible that a manufacturer has offered such a repli-racer to the public. The D16RR is literally a MotoGP bike built for the street. And not those scrawny 800cc prototype racers currently on the grids – we’re talking the big-gun near-liter-sized versions. As such, the RR carries a compact 989cc V-Four engine inside a version of Ducati’s trademark tubular-steel trellis frames.

The Desmosedici RR is a lust-inspirer of the first order. Just ask D16RR owners like Jay Leno, Brad Pitt and Tom Cruise.

The engine itself is a jewel. It features the same bore and stroke measurements (86.0mm x 42.56mm) as those on Ducati’s 2006 racebike, the D16GP6. It uses the “Twin-Pulse” firing order in which the crankpins are offset by 70 degrees (cylinders fire at 0°, 90°, 290° and 380°) to generate what Ducati terms as “soft pulse timing.”

No soft pulses are felt from the D16’s saddle – this thing snorts and sprints around a racetrack like a rampaging demon, as we found out during a few lapping sessions at Willow Springs Raceway.

Our test unit was equipped with the race ECU and exhaust system included with each Desmosedici, a no-brainer swap for the standard street exhaust. So equipped, it is said to achieve the magic 200-horsepower mark at 13,800 rpm when measured at the crankshaft. As for rear-wheel power numbers, those who have had it on a Dynojet dyno say it’s pushing nearly 180 hp. Peak crankshaft torque of 85.3 ft-lbs arrives way up at 10,500 rpm.

'The Desmosedici is like a barely tamed wild animal.'

I was anticipating the D16RR to be high-strung, and its rumpity idle and menacing bark when revved did little to assuage those feelings. But then, despite a heavy clutch pull, the 16RR pulled out of pit lane smartly and without frantic revs, despite its light flywheel effect.

Yet this is no pussycat. Get hard on the throttle, and the D16 romps forth like a Gixxer on nitrous! It shows itself to be quite torquey but then comes on with a wicked surge past 10,000 rpm that inhales literbikes on straightaways like they are 600s. Every straight, no matter how short, becomes a passing opportunity. Vibration gets intense at high revs, putting in the mind of the rider a question: “Are you sure you want to use that much throttle?”

The Desmosedici gathers speed like no sportbike we’ve ever ridden.
That trio in the background was just three of many at Willow Springs which fell victim to the D16’s outrageous power-to-weight ratio.

Yes we do!

The Desmosedici is like a barely tamed wild animal. It’s highly visceral and with an intensity that threatens to overwhelm a rider’s senses. It sounds downright angry on trailing throttle, as a 13.5:1 compression ratio threatens to skid the rear wheel if not for the racing-style slipper clutch. At neutral throttle it emits a menacing grrrrrr! that would be antithetical to anything from, say, Honda. The throttle response from the 50mm Magneti Marelli throttle bodies with 12-hole 'microjet' above-throttle injectors is a bit snatchy, adding to the brutish impression.

The D16’s handling characteristics are similarly racerish. Its chassis geometry (24.5-degree rake, 3.8 inches of trail and 56.3-inch wheelbase) is said to be identical to the MotoGP racer, but these numbers are fairly conservative in the street-sportbike realm. So, despite the reduced gyroscopic forces from the ultra-lightweight forged-magnesium wheels and a relatively light claimed dry weight of 377 lbs, the D16RR doesn’t flick into corners as quickly as expected.

And, like other racebikes I’ve sampled, the Desmosedici proved to be sprung too stiffly for my minimal weight and talent. The suspension was made more compliant after some adjustments, but its heavy springs remained too unyielding – I could still feel the rear end topping out over bumps. Its pegs are high and very rear-set, making it surprisingly difficult to drag a knee. And the $72K price tag doesn’t encourage pitching it in with abandon! Basically, the supremely capable D16 scoffs at the abilities of mere mortals.

"Never have I ridden a machine more capable of exacerbating my ineptness than this 400-lb pit bull," said senior editor Pete Brissette after a wide-eyed session aboard the Desmo.

The Desmosedici is also unique for its specially developed Bridgestone tire combination. It uses a typical 120/70-17 front, but at the rear is a 16-inch (instead of 17) hoop on which is mounted a 200/55-16 ’Stone. Despite the intended grip enhancement of this oddball size, the D16’s devilish motor proved to be willing and able to spin up the tire exiting Willow’s sweeping Turn 9 and onto the front straight.

Forged-magnesium Marchesini wheels, Brembo monoblock brakes and a pressurized Ohlins fork. You can’t buy better stuff.
If you ain’t got your number by now, good luck on eBay!

Despite the intended grip enhancement of this oddball size, the D16’s devilish motor proved to be willing and able to spin up the tire exiting Willow’s sweeping Turn 9 and onto the front straight.

'...the most mind-altering aspect of the D16RR is the part when the gloriously wicked V-Four comes on cam and hurls itself into the next corner with a 14,000-rpm wail'

No matter the gear, the Desmo’ pulls ferociously and demands full attention. Shifts from the cassette-type six-speed gearbox are thankfully smooth, as info from the LCD bar-graph tach is impossible to take in during the bike’s banshees-from-hell increase of velocity. The hyper acceleration makes a rider wish for less fore-aft seating room, as there’s no bum stop in the carbon-fiber subframe to prevent a rider’s frightened ass from sliding rearward. A test rider with more skill than I saw a heady 170 mph on the 16RR’s speedometer on Willow’s shortish front straight.

Braking from such considerable speeds is ably handled by a set of Brembos that are reputedly the same as the MotoGP bikes use in wet weather. One-piece monoblock calipers put a firm but not abrupt bite on 330mm steel discs. They actually don’t feel as aggro as the 1098’s sharp front binders but are nonetheless very powerful given a strong squeeze. Corner entries are also aided by an excellent slipper clutch and stiff springs in the gas-charged Ohlins fork.

Like all Ducatis, the Desmosedici is stable when laid over on its side, but a combination of the stiff springs and the possibility of tens of thousands of dollars in damage that a simple crash might entail kept Casey Stoner-esque elbow-dragging thoughts from reaching my hands.

But the most mind-altering aspect of the D16RR is the part when the gloriously wicked V-Four comes on cam and hurls itself into the next corner with a 14,000-rpm wail. Race-prepped R1s easily fall victim to the claimed 200 horsepower on tap like krill to whales.

So, there’s a lot to like about the thrilling Desmosedici, but its big-ticket price tag doesn’t guarantee perfection. Along with the racer-stiff springs, a street rider will also be disappointed in the amount of heat given off by the 102-dB racing exhaust pipes that exit out the upper part of the rear tail constructed from ceramic carbon fiber. And, for as much as this bike costs, we might’ve expected a traction-control system like the potent 1098R’s.

On the plus side, the Desmosedici offers an unparalleled three-year warranty that includes free service. Its first major service is due at 7500 miles – we wonder how long it will take most D16 owners to pile on that many miles! Also, in addition to the race exhaust and ECU, the D16RR is also delivered with a bike cover and a track stand.

Draws a crowd, every time.

The Desmosedici RR we tested was the so-called “Team Version” that mimics the factory’s Marlboro-sponsored Corse GP bikes with its broad white fairing stripe; a team sponsor decal kit is provided with each bike. Also available is another version in the same “Rosso GP” color (a shade lighter than typical Ducati red) and white number plate on the tailsection but without the white stripe.

Sadly for trust-funders, movie stars or hedge-fund managers, all 1500 examples of the Desmosedici RR have been spoken for. If you’re lucky, you might find a potential customer who has backed out of their $5000 deposit. Otherwise, you’ll be stuck on the rollercoaster that is eBay. If you’ve got deep pockets, you won’t want to miss out on this brilliant and humbling machine that looks as good in a living room as it does on a racetrack.

Husaberg 450 Enduro

By Dirck Edge

When KTM bought Husaberg several years ago, Husaberg loyalists immediately wondered about the direction KTM would take their beloved company. Husaberg had always been a maverick, and employed eccentric design and technology to develop bikes that developed a virtual cult following. For a while, it almost seemed like KTM would let Husaberg die a quiet death.

Now, KTM appears to be using Husaberg as a premium brand employing new, radical technology that may eventually work its way into KTM's own line-up. The 2009 Husaberg 450 Enduro (likely to be called the FE450 in production) is the perfect case in point. What is so radical about the new Husaberg 450? A number of things, really.

As children, we learn about gyroscopic forces while playing with common toys. Spinning a top, for instance, or playing with a yo yo. When an object spins, it creates resistance to movement (inertia). Aprilia, for example, raised the effective center of gravity of its flagship sport bike (the Mille) several years ago in order to make the bike turn better. This confounded many observers, but the fact of the matter is that Aprilia addressed a fairly simple engineering principal regarding location of the crank and its effect on handling.

The new Husaberg design addresses this concept in a radical way. The position of the crank on the new 450 (which actually will displace 448.6cc) has been moved more than a few millimeters (which Aprilia accomplished). In effect, the crank has changed time zones. Nearly four inches higher, and more than six inches rearward of last year's crank position, Husaberg has attempted to place crank inertia precisely at the center of the rolling axis of the new bike. According to a Swede who has been racing the machine (quite successfully) in the World Enduro championship, the new bike handles like a machine of much smaller displacement (think about a 250cc motocrosser versus a 450cc motocrosser). This is precisely why Husaberg undertook the design exercise in the first place.

While radically repositioning the crank shaft, Husaberg designed the new single in a manner that lays the cylinder nearly flat (at a 70° angle). This opened up space for a uniquely placed airbox and fuel tank, which aid performance and further centralize mass. Husaberg is also employing a plastic rear subframe on the new chassis. According to Husaberg, this makes the subframe lighter and stiffer, while allowing a more complex shape that will accommodate the mounting of electric components and closer integration of the muffler system.

So there you have it. KTM is letting Husaberg be Husaberg, after all. This new Enduro model won't be cheap, but it just might be more nimble than any dirt bike of comparable displacement. The new FE450 should go on sale later this year.

Aprilia Dorsoduro

Supermoto Style Done Just Right

By Yossef Schvetz, Jul. 31, 2008, Photography by Piaggio
For Aprilia’s sales floor managers: If a potential Dorsoduro buyer walks into your dealership, blindfold him and seat him on the Dorsoduro, start the engine and let him play with the throttle. Another sale - done.

It’s been a long, long time since an engine’s sound got me so horny, provoking uncontrollable spasms in my annular muscles down there and unhealthy tension in my branded knickers. In our PC/castrated- exhaust era, we’ve seemingly forgotten just how important the aural appeal of a bike really is. Need more? The Dorso’s sound could be likened to a good mix of industrial techno grind with Uzi sub-machine gun at full chat undertones, and it perfectly depicts this little mean machine’s attitude: Nervous, raring to go, craves for your inputs at any given moment and responds to them with infantile enthusiasm.

2008 Aprilia Dorsoduro brings a new take on the supermoto theme.

The visual side of this multimedia experience doesn’t lag behind. This is Miguel Galuzzi’s first full project at Aprilia, and it’s not hard to see that the guy burned the midnight oil, sketching and modeling foams deep into the night. I am downright tented to define the Dorsoduro as his finest creation ever, and that’s quite a compliment considering that Galuzzi penned the original Ducati Monster. It’s not easy to find other scoots that have such a precise and well-defined vision, such an array of well-distilled and exciting forms. In my eyes, the Dorsoduro can take a well-deserved pole position in the “moto design” starting grid, sharing the front row with other luminaries such as the Hypermotard and the last version of KTM’s 990 supermoto. As we’ll see, it’s addressed at quite a different type of rider, but that’s for later.

So then, former Aprilia president Ivano Beggio isn’t around anymore, and Piaggio, the big Italian two-wheeled mama holds the reins. But still, this bike really captures the pioneering spirit of Aprilia, being daring, original, high-techy and, as noted, the design could burn holes through walls. Just a mid-sized supermoto, and yet Aprilia put its best engineering resources into this one, and the result is quite original in that sense.

2008 Aprilia Dorsoduro brings a new take on the supermoto theme.

It’s easy to start from the cycle side of things, as the frame borrows heavily from the last small Twins family, the SXV/RXV 450-550 twins. Not a bad bloodline, as the smaller V-Twins have conquered already a world supermoto championship or two. Just like in those, the front part of the frame is steel tube trellis affair that meet cast ally members midway above the mill’s V center. It’s cool-looking even if it reminds a me a bit of the MV F4’s solution, not a bad inspiration source after all.

The engine’s just as high tech. Not yet another Big Twin but a 750 and that’s already a sign that something is different. Unlike the last crop of 1000cc-plus Twins that need to sacrifice the perfect balance 90-degree angle in order to keep bulk in check (see Buell, KTM, Morini), by being smaller, Aprilia’s Twin has that magic number between its jugs. No wonder that on the saddle this engine felt really smooth. A stacked gear-shaft layout keeps the mill’s length in check in order to maximize swingarm length.

But the real gem is the full fly-by-wire throttle that fully controls the butterfly valves in the throttle bodies according to the inputs from the rider’s right hand. Aprilia has been among the first manufacturers to play with ride-by-wire in its MotoGP contender, the RS3 CUBE 990. Although Yamaha has beaten Aprilia in the race for a production system with its R6, it’s interesting that the guys from Noale still went for such a system in a non-all-out performance tool like the Dorsoduro. By gaining total command from the engine, Aprilia didn’t have much trouble in adding three different power settings. A rider can toggle between Rain, Standard and Sport. Guess where I left it most of the time… ?

The most interesting bit of spec about this new engine is not the impressive 92 claimed horsepower, a healthy output that should put Ducati’s Hypermotard 1100 under some pressure. It’s actually the fact that a peak torque of 60 lb./ft is achieved at a lowly 4500 rpm, smack in the middle of the powerband! Aprilia wisely chose to go for friendly and available torque rather than record numbers. If with such a mild state of tune this little V is capable of 92 hp at 8750 rpm, then with some simple hot-rodding, it should be able to rev up to 12K and deliver 600SS numbers. Don’t be surprised if super sporty middleweight shows up in Aprilia’s line up sooner than later.

With such a lush tech spec, it’s not surprising to find in the Dorsoduro other nice features like “Wave” brake discs, radial calipers, a double taper handlebar, and fully adjustable suspension.

Off we set, following a riding guide sent by Piaggio. The guy knows how to gas it, and after warming up for a few miles on the good old Tuono, I’m all set to swing a leg over the Dorso’. A few minutes into the ride and I’m all smiles. The long and flat saddle let’s you place your bottom wherever you see fit – for tall and spindly guys like me, that’s already a very good start. Gas it now and my cheeks are splitting from so much grinning, the aforementioned soundtrack puts me in real attack mode. Down for first, feather the light clutch and the Dorso drives on with authority, second, third, gears glide in perfectly, fourth, fifth gear, I’m keeping it pinned now, trying to keep our mad guide in my sights.

As expected, the engine is less stellar in the higher reaches of the rev counter. But the fun part comes soon enough. Throw the Dorsoduro into a good bend, and it thrives, flick it good into a tight hairpin and it shines. This thing reacts so happily to steering inputs that I find the 410-lb claimed dry weight, hard to believe. The bike feels like the spec sheet is a good 60 lbs off the mark.

'Down for first, feather the light clutch and the Dorso drives on with authority, second, third, gears glide in perfectly, fourth, fifth gear, I’m keeping it pinned now, trying to keep our mad guide in my sights.'

Bendy bits are over? That’s so sad, and yet roll the throttle on and the drive-by-wire system will find pretty good drive regardless of rpm. Okay, the oomph level down low might not be comparable to the atomic drive of the Morini 1200 or Ducati’s HM1100, but just because of that, the Dorsoduro actually helps you by not being so violent in its power delivery. So I said early on that the Dorso is a different animal, and this is exactly the point. Less brutal than a HM1100 or KTM 990, less intimidating while on the limit, much more friendly than those two hairy beasts. You do end up riding it smoother and faster, a boon if you are not VDB (Thierry van den Bosch, Aprilia’s hard-riding supermoto star).

The Dorsoduro might lack the immense rigidity of the HM1100’s bombproof frame, a rigidity that makes Duc’s Hypermotard a very demanding thing to ride. But exactly for that reason (Aprilia claims to have intentionally designed some flex into the frame), the Dunlop Qualifiers have an easier time finding traction. The little slides and blurbs while cornering hard fool you into feeling that you are some sort of supermoto god. And I am not!

Chill out for some minutes and you’ll find that there’s another side to this “Hard Back” thing (Dorsoduro in Italian) and that you don’t have to be in interception mode all of the time. Trotting along I discover that the engine is real smooth, the throttle response is simply sweet and that the hard-looking, off-road inspired seat is actually very comfortable. Or to put it in another way, this scoot is far from being a narrow focus racer in disguise – it’s actually quite an all-rounder. I could see myself riding one to work on a steady basis.

And that’s exactly the quality that I’ve been missing in all the supermotos I’ve tested so far. I have never fallen in love with supermoto Singles – too little creature comfort, too vibey, too narrow-focused, either as 450s or big 600-650cc Singles (although I’ve yet to ride KTM’s new 690). Big, liter-size supermotos have not convinced me either so far. They might be exciting rides, but on a long-term basis I found them too demanding, too crazy to live with, as one such specimen almost shortened my life when it landed on me (ended up with just three broken ribs… ). And here, all of the sudden, out of nowhere, another approach to the SM theme and Aprilia’s “mid-size SM” just feels so right.

Wot? No complaints whatsoever? Sorry, in my short test ride I haven’t been able to find much to bitch about. While standing at a stoplight after a run, it was a very hot day and there was plenty of heat blowing out from the engine bay, enough to turn my left you-know-what into an omelet. Not really a problem, as most of us have two rounded jewels. Other than that, I heard some colleagues saying that the ride-by-wire response is a tad too aseptic.

But to find out for sure I’ll need to have a Dorso’ for a long-term test. I promise to be a good boy and will take the thing to the nearest supermoto track only once a week.
