Features

Features

  • SUSPENSION: Updated internal valving provides a more balanced feel while also providing more plushness over the small rollers. The shock valving has also been revised to work in conjunction with the new front fork settings.
  • ENGINE: Revised carburetion on all 2021 models ensures better Rideability in all conditions. Consequently, the ignition mapping has also improved, resulting in a more linear and predictable throttle response
  • HYDRO-FORMED FRAME & TANK: The Evo hydro-formed aluminum frame & tank is a work of art that is unmatched in beauty & performance
  • TUBELESS REAR TIRE: A Dunlop tubeless rear tire allows riders to run extremely low tire-pressure for maximum traction
  • DUAL MAP SWITCH: A relocated dual map switch allows riders to choose between two power curves
