Upgrade your scooter's CVT transmission with Dr. Pulley 18x14mm Sliding Roller Weights. Unlike traditional round rollers that develop flat spots over time, Dr. Pulley's patented composite sliding geometry features a multi-faceted profile that slides smoothly within the variator ramps ā allowing the variator to open wider and close further for better low-end acceleration, smoother mid-range transitions, and improved top-end cruising. Sold as a matched set of 6.

- Optimized variator travel for better takeoff and increased top speed
- Self-lubricating low-friction nylon composite resists heat and reduces ramp wear
