 Model Year  2007  2007
 Model  YZF-R1  YZF-R1
 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.
 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.
 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.
 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.
