2007 Yamaha YZF-R1

Additional Features:

• Redesigned headlights provide great illumination and distinctive style, while the LED taillight is light, bright and highly efficient.
• Adjustable LCD illumination and multi-function digital gauges: adjustable shift light, odometer, dual tripmeters, water temperature, air temperature, full-time clock, lap timer and large 15,000 rpm analog tachometer.
• New-design fairing with bigger Ram-Air intakes and screwless windscreen provides maximum aerodynamic efficiency and engine performance.
• Sticky 120/70-ZR17 and 190/50-ZR17 radial tires for incredible grip and precise handling.
• Forged footpegs are extra durable and light.
• Extensive use of hollow bolts and lightweight fasteners helps trim overall weight.
• 8.6 Ah battery is compact and light.
• Durable #530 O-ring–sealed drive chain.
• Standard toolkit located in convenient storage compartment under passenger seat.

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 310 mm 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 43 mm tubes has been re-valved to complement other chassis changes.
• Piggyback rear shock now offers both high- and low-speed compression adjustability, rebound damping and a new, twist-style spring preload adjuster.
• Light, five-spoke wheels enhance acceleration, deceleration, handling and suspension action.

Engine:

• Short-stroke 998 cc 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 140 mm 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, 77 mm bores.
• Narrow-angle four-valve combustion chambers produce a highly efficient 12.7:1 compression ratio; 31 mm titanium intake valves and 25 mm 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 mid-pipe 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.

Key Features:

• 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 310 mm discs generate the kind of braking power a bike like the new R1 requires.
