Info
2015 Yamaha YZF-R6Key Features May Include Light, powerful and bristling with knowledge gained from years of racing, the YZF-R6 is the most advanced production middleweight motorcycle Yamaha - or anybody else - has ever built. The YZF-R6 was the first production motorcycle with a fly-by-wire throttle systemfor flawless response under all conditions. Straight frame concept: developed from the Yamaha M1 GP machine, the YZF-R6s steering head, swingarm pivot and rear axle all lie in a straight linefor unsurpassed handlingwith an inline four- cylinder engine designed for optimal layout and mass centralization. Slipper-type back torque-limiting clutch greatly facilitates braking/down shifting from high speed. Formula 1-style air management presents very small frontal area for excellent aerodynamics; ram-air induction ducts cool, high-pressure air through the steering head for optimal combustion, more horsepower and enhanced engine cooling. The YZF-R6 is the AMA Supersport Champion in its rookie season. Features & Benefits
Engine
Compact, lightweight 67 x 42.5mm 599cc DOHC 16-valve liquid- cooled inline four-cylinder features titanium valves, 12.8:1 compression and compact combustion chambers for awesome, lightning-quick response. YCC-T (Yamaha Chip Controlled Throttle) 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. Back torque-limiting slipper clutch greatly facilitates braking and downshifting from high speed. Close-ratio six-speed transmission delivers seamless power and maximum acceleration. Despite the increased bore, piston and pin weight has been reduced for more power and smoothness; 1mm smaller main journals reduce friction while 1mm larger connecting rod journals increase performance. Compact slant-block engine design uses widely triangulated gearbox shafts to make the GP-derived, straight frame concept work; optimum weight distribution and excellent handling are the result. GP-style titanium muffler contributes to mass centralization, and contains EXUP, and an O2 sensor and catalyzers for a broad powerband and spot-on injection. Linerless, direct-plated ceramic-composite cylinder bores mean greater heat dissipation for consistent power delivery and reduced friction also a narrow engine. Cool magnesium valve and engine covers are light and stylish. Curved radiator with twin-ring cooling fans keeps everything cool. Direct ignition coils, dual-electrode spark plugs and high-output magneto deliver extremely accurate, reliable firing. Chassis/Suspension Deltabox aluminum frame incorporates GP thinking in terms of engine positioning and rigidity for the ultimate in 600 class handling. MotoGP-style 52.5-percent front-wheel weight bias helps produce razor-sharp handling. Light, Controlled Fill 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. 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.
