600CC Sportbike Shootout

Twenty years ago the Supersport class spawned a revolution in the sportbike world. Racing heroes the likes of Miguel Duhamel and the Hayden brothers had replicas of their race-winning bikes rolling off showrooms as fast as dealers could uncrate ‘em. The classic ‘win on Sunday, sell on Monday’ maxim was as heavy as the trophies these athletes hoisted. It was the heyday of sportbikes. A lot has changed since then, including the engine displacement as the class evolves, and while the popularity has cooled there are still riders who value apex strafing middleweight performance. It’s for those we present the track edition of our annual Supersport Shoot out.

SUPERSPORTS < 600cc

In the motorcycle dictionary, Supersport can mean a lot of things. But for us the explanation is simple: Japanese-built sportbikes that employ high-revving and state-of-the-art, liquid-cooled 599cc Inline Four engines. For 2013 there are three: Honda’s CBR600RR ($11, 800), Yamaha’s YZF-R6 ($10, 990) and Suzuki’s GSX-R600 ($11, 599). Where’s the Kawasaki? It has jumped to the middleweight class, but we’ll get to that in a bit…

Honda joins this year’s shootout with its fresh-faced CBR600RR. After a lengthy hiatus from any hardware updates at the factory, the two-time Supersport Shootout champ finally comes to bat with fresh components, including new wheels and suspension from Showa. It also got a facelift and some subtle aerodynamic improvements for greater efficiency. Last time around Honda finished in the runner-up spot despite being one of the oldest platforms in the contest. Will this be the year Big Red reclaims the top spot?

Yamaha returns with its racy little YZF-R6. Last updated five years ago, the R6 still continues to rack up race wins in both the amateur and professional ranks worldwide. Although it’s been a while since the Yamaha last scored a Supersport Shootout victory it’s always a favorite known for sharp handling and punchy top-end engine power. Joining Yamaha in the unchanged-for-2013 category is Suzuki with its GSX-R600. To date, Suzuki is the only Japanese brand that hasn’t scored a shootout win despite success within the AMA Daytona SportBike class. Could this be the year Suzuki finally lives up to its “Own the Racetrack” mantra?

MIDDLEWEIGHTS > 600cc
These are the full fairing sport motorcycles that fall outside of the traditional segment. They include Ducati’s V-Twin-powered 848 EVO ($14, 995), Triumph’s Daytona 675R ($13, 499) and the MV Agusta F3 ($13, 999)— the latter pair powered by 675cc Inline Triples. Then we have Kawasaki’s 636cc-powered Ninja ZX-6R (, 699), and the machine that started it all nearly 30 years ago: Suzuki’s GSX-R750 (, 199).

Ducati’s 848 EVO is still the platform the Italian brand campaigns in the middleweight class. Although it’s been a few years since it last got a re-fresh, it has the distinction of offering the largest engine in the category. In spite of its obvious horsepower advantage and early adoption of traction control it hasn’t been enough to propel the Bologna-built bike to the top spot, but it has come close. Will this be the year of the Ducati?

Triumph recorded a decisive win last time with its Daytona 675R (see the 2011 Supersport Shootout IX Track). This season it’s in a better position than ever to retain the No.1 spot with an all-new machine that sports a redesigned engine and chassis. The Triumph has always been a favorite, but fully redesigned models always come with risk of first-year teething problems. Will this play a factor in the results?

After years of question marks we finally add MV Agusta’s F3 to the mix. The MV has already proven that it’s a formidable competitor during last fall’s 2012 Middleweight Sportbike Shootout and has even proven its might in World Supersport competition by nabbing a podium spot at England’s Donington Park round a few weeks ago. We’re excited to see how it stacks up stock for stock against the best of the best.

For the last few years Kawasaki has adhered to the displacement rules of its fellow Japanese OEMs, but this season it ups the ante with its 636cc Ninja ZX-6R. In addition to the stroked engine, the Ninja gets suspension and braking updates as well as traction control—making it the first Japanese brand to employ this rider aid in the Supersport class. Kawasaki has won more of our big shootout competitions than any other manufacturer and is in an advantageous position to extend its lead.

Last but certainly not least is Suzuki’s GSX-R750. A sportbike classic, the middle GSX-R finds itself in motorcycling no man’s land between the 600 and 1000 class. Despite not being eligible for competition in the former class, the 750 still competes in this middleweight genre based on its price alone. Due to the obvious advantage of its Inline Four, we didn’t include the 750 in the official ranking order, but we did assess its scores separately just to see exactly where it slots in your purchasing decision.

PROTOCOL
For the test we returned to Southern California’s Chuckwalla Valley Raceway and spun two days’ worth of laps on its 2.68-mile road course. Early summer weather had the mercury hovering near 115 degrees, throwing a curve ball and making for some interesting (and exhausting) results. We utilized Chuckwalla’s more traditional 17-turn clockwise configuration providing a good mix of slow-to-medium speed turns as well as moderate braking zones as a gauge for where each one of the bikes excel and where they don’t.
