World Superbikes : 2009 Yamaha YZF-R6


World Superbikes growing up with new Yamaha machine with perfect design.Its called YZF-R6

Key Features
  • 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.
  • Slipper-type back torque-limiting clutch greatly facilitates braking/downshifting from high speed.
  • The YZF-R6 achieves fuel economy up to an estimated 40 mpg** with a fuel tank that holds 4.6 gallons of gas.


New for 2009
The Engine Control Unit (ECU) has remapped YCC-T settings to optimize power output in each gear, to achieve smooth, linear power delivery out of the turn, with excellent overall drivability.


Engine
  • Compact, lightweight 67 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 funnel length for an amazinglyf broad, smooth powerband.
  • A magnesium subframe removes weight from the rear of the motorcycle for increased mass centralization.
  • Fork height adjustability and rear ride-height adjustment accommodates 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 powerband, spot-on injection and emissions compliance.
  • Linerless, 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.
Chasis and Suspension
  • Deltabox aluminum frame incorporates GP thinking in terms of engine positioning and rigidity for the ultimate in 600-class handling.
  • A die-cast swingarm pivots high in the frame, for increased antisquat 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.
  • 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.
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.
