Dr. Pulley Sliding Roller Weights 20x15

The Dr. Pulley Sliding Roller Weights 20x15 are premium performance variator rollers designed for enhanced acceleration, smoother power delivery, and longer-lasting CVT operation in compatible small-displacement scooters, mini UTVs, and GY6-style engines. These sliders are a popular upgrade for the Honda Navi (110cc) and Polaris RZR 200 (youth EFI model with GY6-based CVT), as well as similar setups like Honda PCX, SH series, Genuine Blur, and many 125-150cc GY6B/Znen engines.

Unlike traditional round rollers, Dr. Pulley's innovative sliding (not rolling) design features a unique flat-sided shape that reduces friction, allows the variator to shift more efficiently, and provides a broader effective gear ratio range.

Key Features & Benefits

Sliding Design Advantage: Slides up-and-down the ramp instead of rolling—up to 20% better performance than standard round weights, with quicker response, reduced belt slip, and improved acceleration off the line.
Superior Durability: Lasts up to 18% longer with 22% less material wear; made from high-grade, wear-resistant material that handles heat and high RPMs better than stock rollers.
Performance Gains: Lighter weights deliver snappier low-end takeoff and better hill climbing; heavier options maintain or boost top speed. Expect noticeable improvements in throttle response, mid-range pull, and overall CVT efficiency—ideal for trail fun in the RZR 200 or zipping around town on the Navi.
Exact Fit: Size 20x15mm (diameter x width), set of 6 pieces. Direct replacement for stock rollers in:
- Honda Navi (stock often ~17g round; sliders commonly run 12g–15g for big gains)
- Polaris RZR 200 (GY6-compatible CVT; aftermarket 20x15 rollers widely used)
- Honda PCX 125/150, SH 125/150, Genuine Blur 220i, and many GY6 125-150cc engines
