Dr. Pulley 20x17 Sliding Roller Weights - Vespa/Piaggio 200+

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.
