Dr. Pulley 20x17 Sliding Roller Weights unlock the true potential of your Vespa or Piaggio 200�300cc CVT. Unlike traditional round rollers that develop flat spots and notches over time, Dr. Pulley's patented non-round shape slides through the variator ramps � allowing the variator to open wider for higher top speed and retract further for stronger low-end pull. Available in 9.5g�13g to match your riding style. SKU: SR2017.
Installation Note: Orientation is critical. The �blocked� side of the slider must face the direction of rotation. Inspect variator slides for wear before installing � worn guides will prevent smooth sliding action.
