• Lightweight forged pistons operate at a 11.8 to 1 compression ratio on 87-octane fuel.

  • Exclusive Genesis Extreme exhaust system has four straight-out-the-back head pipes that collect through an X-style crossover system to two rear exhaust outlets. This design minimizes exhaust flow restriction for maximum power and efficiency.

  • Exclusive Exhaust silencer position assists vehicle balance for excellent handling.

  • Exclusive Gear-driven output shaft allows high engine RPM and a lower, more efficient drive clutch speed. Rubber dampened isolation system reduces torque pulses for greater clutch and V-belt life. Output shaft also drives water pump and oil pump.

  • ExclusiveFour 37mm constant-velocity carburetors have high airflow with easy throttle effort. Industry-leading liquid-heated carburetors maintain excellent throttle response and fuel economy.

  • Exclusive Lightweight and compact 18-pole magneto uses rare-earth flywheel magnet material to generate 425 watts of electrical power.

  • Exclusive Lightweight and strong motorcycle-type engine mounts effectively isolates vibration while maintaining V-belt alignment.

  • Dry-sump oiling system increases engine power and reduces starting effort.

  • Electric starter motor output delivers 1.5 times more cranking power than typical 2-stroke starters with no increase in size due to use of powerful rare-earth magnets. Easier cold weather starting is achieved while reducing weight by 2.8 pounds.

  • Low-maintenance battery develops strong cranking power and saves weight.

  • New aggressive clutch calibration is used due to the Genesis Extreme 4-stroke engine's high-torque and high-horsepower characteristics. New high-force drive clutch weights, working with a new multi-angle helix, generate high belt squeeze force for quick acceleration and responsive back-shift.

  • Camoplast Predator track, featuring 1' lugs, increases acceleration and provides excellent handling. This track is 1.5 pounds lighter than the SRX track.

  • Compact hood shape reduces aerodynamic drag for increased top speed.

  • Handling

    Exclusive Deltabox chassis 94fbr fl studio 12.5. has up to 4 times the torsional rigidity than the competition while reducing chassis weight by 9 pounds. This stiff design controls chassis flex for a solid feeling under hard acceleration, quick response when cornering and smooth suspension action in the bumps.

    Double wishbone front suspension moves through 9' of vertical travel with zero bump-steer and no spindle caster angle change for razor-sharp handling and confidence in the bumps. Optimum front suspension travel delivers excellent bump-eating performance with flat high-speed cornering.

    2005 Yamaha Rx1 Review

    Powerful and lightweight electric start feature is standard equipment on all RX-1 models. No more rider overheating from trying to pull-start your snowmobile on cold mornings - no more recoil rope stains on your jacket.

    Yamaha Rx1 Specs

    Pro-Action SXV long-travel rear suspension soaks up the bumps with 11.5' of vertical travel. This long travel rear suspension delivers performance, confidence and comfort when running through tight corners or through miles of stutter bumps.
