CVT Tuning Guide

  • Lighter Rollers (4.0g–5.5g): Quicker off-the-line acceleration and better hill climbing. Best for heavier riders or stock motor setups.
  • Heavier Rollers (6.0g–8.0g): Lower cruising RPM and higher top-end speed. Best for lighter riders or big-bore builds.

  • Dimensions: 17mm diameter x 12mm width
  • Quantity: 6 matched rollers per set
  • Available Weights: 4.0g to 8.0g in 0.5g increments
