Description

These Dr. Pulley 20x17 Sliding Roller Weights are a set of six sliders that unlock more performance from the CVT on Vespa and Piaggio 200-300cc scooters. Unlike round rollers that develop flat spots over time, Dr. Pulley's patented non-round shape slides through the variator ramps. That lets the variator sit lower for stronger launches and open wider for higher top speed. Choose from ten weights, 9.5g to 13g, to match your riding style.

Features

Patented sliding shape: Resists the flat spots and uneven wear common with round rollers.
Wider gear range: Stronger take-off and higher top end compared to round rollers.
Bearing-grade material: Low-friction, self-lubricating composite.
Non-abrasive fiber: Gentle on aluminum variators.
Brass-bushed center: Smooth, even contact with the variator.
Ten weight options: Fine-tune acceleration versus top speed.

Weight Selection Guide

Lighter (9.5g to 10.7g): Better hill climbing and city acceleration, higher RPM cruising.
Mid-range (11g to 12g): Balanced daily commuting.
Heavier (12.5g to 13g): Higher top speed and lower RPM cruising on flat roads.

Installation Notes

Orientation is critical. The blocked side of each slider must face the direction of rotation. Inspect the variator slide pieces for wear before installing, since worn guides prevent smooth sliding action.
