New features in Yamaha YZF R6..

Picture of 2009 YamahaYZF R6 sport bike.

The 2009 Daytona 200 winner is back! The Yamaha YZF R6 is ready for the street or track. Light, powerful, and bristling with knowledge gained from years of racing, the YZF-R6 is the most advanced production 600cc motorcycle Yamaha—or anybody else—has ever built. The YZF-R6 was the first production motorcycle with a fly-by-wire throttle system—for flawless response under all conditions. YCC-I, Yamaha Chip Controlled Intake, is used on the R6 to vary intake tract length for excellent cylinder filling and a broader power-band. Yamaha YZF R6 on the higher-revving its benefits are even more pronounced. Back torque-limiting slipper-type clutch greatly facilitates braking/downshifting from high speed. Close-ratio 6-speed transmission delivers seamless power and maximum acceleration.

Engine specs:

Compact, lightweight 67mm x 42.5mm, 599cc DOHC 16-valve, liquid-cooled titanium-valved four-cylinder has a compression ratio of 13.1:1, for great response. Domed pistons with valve cutouts produce a compact combustion chamber. Fuel injection mapping for the YCC-T—Yamaha Chip Controlled Throttle dual-injector system complements the high compression ratio for great throttle response and reduced engine braking. YCC-I—Yamaha Chip Controlled Intake electronically varies intake tract length for a broader power-band. A magnesium sub-frame removes weight from the rear of the motorcycle for increased mass centralization. Fork height adjust-ability and rear ride-height adjustment accommodate a great range of riders and tires. YCC-T uses a powerful ECU and multiple sensors to provide perfect, smooth engine response and optimal power whenever the throttle is twisted under all conditions. Twin-injector fuel injection: shower-type injectors above each intake funnel help achieve optimum fuel atomization at high rpm. Slipper-type back torque-limiting clutch greatly facilitates braking and downshifting from high speed. Close-ratio six-speed transmission delivers seamless power and maximum acceleration. GP-style titanium muffler contributes to mass centralization and contains EXUP for a broad power-band, and 02 sensor for spot-on injection and emissions compliance. Liner-less direct-plated ceramic-composite cylinder bores mean greater heat dissipation for consistent power delivery and reduced friction. Cool magnesium valve and engine covers are light and stylish. Direct-ignition coils, dual-electrode spark plugs and high-output magneto deliver extremely accurate, reliable firing. Making the Yamaha YZF R6 feel like its rocket-engine on two wheels!

Chasis suspention:

Delta-box aluminum frame incorporates GP thinking in terms of engine positioning and rigidity for the ultimate in 600-class handling. The lightweight swing-arm pivots high in the frame, for increased anti-squat effect and mid-corner stability. TZ-type chain adjusters ease rear tire changes. Yamaha YZF R6 four-way adjustable (preload, high-speed compression, low-speed compression and rebound damping) inverted fork with 41mm tubes increases freedom in setting up for street or track use, soak up the bumps and resist bottoming when braking. Four-way adjustable (preload, high-speed compression, low speed compression and rebound damping) piggyback rear shock delivers exceptional rear wheel tracking and stability. Dual 310mm front disc brakes use forged one-piece radial-mount calipers and radial-pump front master cylinder with adjustable lever for astounding braking power and feel. The casting technique for the five-spoke 17-inch wheels makes the rims light and strong, not to mention wickedly cool-looking. Removable rear shock spacer and adjustable fork ride height allows the rider to tailor the ride position for the best fit and comfort.
