Features

Features

  • Metzeler tires, known for their off- road performance as well as a long-lasting compound, these tires are an added benefit for all riders.
  • A new Nissin rear brake cylinder is an updated version that provides more modulation of the rear brake while still providing the rider with a top-level rear brake feeling over rocks and downhills.
  • Extra wide billet aluminum foot pegs with stainless steel gripper pins provide the rider with a strong, yet light platform.
  • Narrow shrouds give the rider more freedom of movement, especially in corners. Designed to be sleek, simple, & attractive.
  • Quick release front axle pull, red anodized alloy lever for quick removal of the front axle during tire swaps.
  • The Kayaba C46 rear shock is a collaboration of Kayaba and Beta led to the development of a shock that is particularly effective in enhancing the Rideability of the bike under all conditions. KYB shocks are seen as a gold standard in the racing scene in terms of their ability to absorb big square-edged hits while at the same time, providing a supple ride over the smaller, lower speed bumps.
  • A new frame has been developed to increase the rigidness of the overall bike which has improved the turning stability of the chassis.
