Yamaha YZF-R1

The Yamaha YZF-R1 bike, launched in 1998, revolutionized the sport bike landscape by successfully combining the awesome power available previously in the true liter class (1,000cc) with the lightweight and responsiveness that a 600-class chassis affords.Over the years, despite maintaining its distinctive sharp look, the R1 has undergone technical up gradations to keep pace with the times. The 2006 edition features a short-stroke 998cc DOHC, 20-valve, liquid-cooled inline four-cylinder engine that produces a peak power of 175 bhp.The dual-valve fuel injection system uses motor-driven secondary throttle valves and 32-bit ECU for responsive, instantaneous power delivery. The refurbished Delta box V frame, revised forks and a 20mm longer swingarm facilitate superb handling in the R1. In 2006, to celebrate the 50th anniversary of Yamaha racing in America, Yamaha released a Limited Edition yellow/white/black YZF-R1 in original Yamaha racing colours.

Yamaha YZF-R1 Technical Specifications

Yamaha R1 India
 Key Features:

  1. Light, powerful and packed with trickle-down MotoGP technology, the YZF-R1 is the most advanced Open-class production motorcycle ever built.
  2. The YZF-R1 uses the YCC-T fly-by-wire throttle system for flawless response under all conditions.
  3. 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.
  4. Slipper-type back torque-limiting clutch greatly facilitates braking/downshifting from high speed.
  5. Aluminum Deltabox frame and swingarm take Open-class handling to the next performance level.
  6. Six-piston radial-mount front brake calipers and 310mm discs generate the kind of braking power a bike like the R1 requires.


  * 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.
  * 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.


  * A Deltabox frame tuned for optimal flex carries the lay-down four-cylinder stressed-member style for great handling and efficient aerodynamic penetration.
  * A 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.
  * 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:

  * Cool headlights provide great illumination and distinctive style, while the LED taillight is light, bright and highly efficient.
  * Adjustable LCD illumination and multifunction digital gauges: adjustable shift light, odometer, dual tripmeters, water temperature, air temperature, full-time clock, lap timer and large 15,000-rpm analog tachometer.
  * A fairing with big 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.
