2007 Yamaha YZF-R1 Candy Red, 2007 Yamaha YZF-R1 All-new, light, powerful and packed with trickle-down MotoGP trickery, the YZF-R1 is the most advanced Open-class production motorcycle ever built. Key Features May Include All-new, light, powerful and packed with trickle-down MotoGP trickery, the YZF-R1 is the most advanced Open-class production motorcycle ever built. All-new inline four-cylinder engine is the most powerful, tractable R1 powerplant ever, thanks partially to the world s first electronic variable- length intake funnel system. The YZF-R1 uses the YCC-T fly-by-wire throttle system for flawless response under all conditions. Slipper-type back torque-limiting clutch greatly facilitates braking/downshifting from high speed. All-new aluminum Deltabox frame and swingarm take Open-class handling to the next performance level. New, six-piston radial-mount front brake calipers and 310mm discs generate the kind of braking power a bike like the new R1 requires. Features & Benefits Engine Short-stroke 998cc DOHC, 16-valve, liquid-cooled inline four- cylinder engine produces more tractable power than ever. Yamaha Chip Control Throttle controls a 32-bit ECU fuel injection system for super-responsive, smooth, instantaneous power delivery. Yamaha Chip Control Intake electronically adjusts intake funnel length between either 65 or 140mm for an amazingly broad, smooth powerband. Two-piece ergonomically designed fuel tank carries fuel in the rear section, for good centralization of mass, while the front half contains a Ram-Air-fed airbox for increased power. Lay-down design cylinder head optimizes weight distribution, straightens intake tracts for improved cylinder filling, and allows frame to pass over instead of around the engine for great strength and a narrow chassis. Closed-deck cylinder block increases strength and allows a narrow engine in spite of big, 77mm bores. Narrow-angle four-valve combustion chambers produce a highly efficient 12.7:1 compression ratio; 31mm titanium intake valves and 25mm exhausts controlled by new, high-lift cams flow plenty of air. Light and strong nutless connecting rods with fractured big ends produce a quick-revving engine with excellent high-rpm durability. High silicon-content ceramic-composite cylinder sleeves ensure great heat dissipation for consistent power delivery and reduced friction. Close-ratio six-speed gearbox with triangulated shaft layout for great strength, compactness, and quicker acceleration. Ramp-type slipper clutch makes braking from speed into tight corners while downshifting smoother and therefore faster. Redesigned titanium underseat exhaust system (with stainless steel midpipe and catalyst) provides excellent cornering clearance and a broad, seamless powerband.
