Dr. Pulley
Dr. Pulley 18x14 Sliding Roller Weights: GY6, Genuine, Lance
Description
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 — 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.
- Patented sliding geometry — eliminates flat spotting common to round weights
- Optimized variator travel for better takeoff and increased top speed
- Self-lubricating low-friction nylon composite resists heat and reduces ramp wear
- Available in multiple gram weights for custom CVT tuning
- Set of 6 matched weights
