Dial in your scooter’s CVT with NCY 20x15mm Precision Roller Weights. Engineered as a high-performance upgrade over factory weights, these rollers feature a low-friction, heat-resistant polymer outer coating that ensures smooth shifting, eliminates flat-spotting, and optimizes your engine’s power band for cleaner acceleration and improved top-end speed. Available in 12g–18g — select your weight above. Sold as one complete matched set of 6 rollers.
Key Features
Low-Friction Polymer Shell: Wear-resistant coating reduces friction against variator ramps and prevents premature flat-spotting.
Precision Weight Calibration: Manufactured to strict tolerances for balanced centrifugal force across the variator face.
Optimized Shifting Curve: Dial in the perfect balance of off-the-line response and mid-range power transfer.
Complete Matched Set: 6 rollers per order, all at the same weight.
CVT Tuning Guide
Lighter rollers (12g–14g): Quicker acceleration and better low-end response — best for stop-and-go riding, heavier riders, or stock engine setups.
Heavier rollers (16g–18g): Lower cruising RPM and higher top-end speed — best for lighter riders, highway commuting, or performance builds.

Mechanic’s Tip: Wipe down the inner variator ramps with brake cleaner to remove all belt dust before installing new rollers. Never add grease to a dry-roll variator — it traps debris and causes flat spots.
