Dr. Pulley 20×17 Sliding Roller Weights – Vespa/Piaggio 200+

Description

Dr. Pulley 20×17 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.
