Description

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.

  • Dimensions: 15mm (Diameter) x 12mm (Width)
  • Available Weights: 3.0g to 11.0g
