NCY 15x12 Performance Roller Weights - Minarelli 1PE40QMB

Precision Tuning: NCY 15x12 Performance Roller Weights Unlock the full potential of your CVT with high-quality NCY 15x12 Roller Weights . An essential component for transmission tuning, these rollers allow you to customize your scooter's acceleration and top-speed characteristics. Replacing worn, flat-spotted rollers restores lost performance and ensures your engine stays in its optimal power band. Why Upgrade to NCY Rollers? Engineered for Performance: Available in a wide range of weights (3g–11g) to fine-tune your scooter for better hill climbing or higher top speeds. Durable Construction: Made with a specialized low-friction coating to resist flat-spotting and provide consistent shifting over time. Maintenance Essential: Over time, rollers develop flat spots that cause "laggy" acceleration. New rollers restore a smooth, linear power delivery. Improved Efficiency: Properly weighted rollers prevent the engine from over-revving, leading to better fuel economy and reduced engine wear.
