2010 Yamaha YZF-R6New For 20101 . The new, 100mm-longer muffler is designed for excellent power characteristics and reduced noise.2 . The ECU settings have been revised for increased performanceFeatures & BenefitsKey Features:The 2009 Daytona 200 winner is back and 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 powerband. On the higher-revving R6, 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: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 powerband.A magnesium subframe removes weight from the rear of the motorcycle for increased mass centralization.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 powerband, and 02 sensor for spot-on injection and emissions compliance.Chassis/Suspension:Deltabox® aluminum frame incorporates GP thinking in terms of engine positioning and rigidity for the ultimate in 600-class handling.The lightweight swingarm pivots high in the frame, for increased anti- squat effect and mid-corner stability. TZ-type chain adjusters ease rear tire changes.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.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.Additional Features:Built-in lap timer is controlled by a right handlebar switch.Multifunction digital and analog instrumentation features: programmable shift light, digital speedometer, analog tachometer, dual tripmeters with miles-on-reserve function, odometer, water temp gauge and lights for neutral, high beam, low fuel and turn signals.
