2007 YAMAHA YZF-R1 - F007713

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 worlds 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.
• 13-percent greater radiator capacity and an aluminum liquid-cooled oil cooler maintain stable operating temperature.
• Direct ignition coils, dual-electrode spark plugs and high-output magneto deliver extremely accurate, reliable firing.
• AC generator behind cylinder block produces a narrow engine with excellent cornering clearance.

Chassis/Suspension

• An all-new Deltabox frame tuned for optimal flex carries the lay-down four-cylinder stressed-member style, for great handling and efficient aerodynamic penetration.
• A new truss-type swingarm is extremely strong and tuned for optimal traction and feedback.
• Dual 310mm front disc brakes; new, six-piston radial-mount calipers and Brembo radial-pump front master cylinder with adjustable lever deliver amazing braking power and feel.
• Fully adjustable KYB inverted telescopic front fork with 43mm tubes has been revalved to complement other chassis changes.
