Top Features:

  • Innovative Engine Design
    A liquid-cooled, DOHC 4-valve, fuel-injected engine with forward-positioned downdraft intake delivers class leading engine power, updated for 2017 to further improve top-end power. This engine design allows for unmatched mass centralization, concentrating the motorcycle’s key components—engine, fuel tank and exhaust system—toward the center of the motorcycle achieving light and nimble handling performance.
  • Updated Transmission
    New gear dogs, revised gear tooth designs and a host of smaller changes create a smoother overall transmission with improved shifting, as well as a stronger overall powertrain for improved durability.
  • Bilateral Beam Aluminum Frame
    A Yamaha’s renowned bilateral beam aluminum frame features compact overall dimensions that balance minimal weight with the strength and rigidity needed for race-winning performance. This frame features a new forged section at the swingarm pivot, and engine mounting brackets for tuned responsiveness, handling and unmatched lightweight feeling.
  • Updated Suspension Settings
    Industry-leading, fully adjustable KYB® spring-type fork with speed sensitive damping features revised valving for improved suspension feel and balance. The KYB® rear shock also features settings optimized for ideal damping characteristics.
  • GYTR® Power Tuner Ready
    Accessory GYTR Power Tuner lets owners adjust air/fuel mixture and ignition timing maps to match engine performance characteristics to the rider and track conditions in a matter of seconds with the push of a few buttons, as well as monitor engine diagnostic codes.
