Precision Tuning: NCY 20x12 High-Performance Roller Weights

Optimize your CVT's power delivery with NCY Performance Roller Weights. Engineered for riders who demand precise control over their gear ratios, these 20x12mm weights allow you to bridge the gap between low-end torque and high-end velocity. Whether you are looking to conquer steep hills in the city or maximize your top speed on the open road, NCY provides the durability and weight accuracy needed to dial in your transmission perfectly.

Advanced Performance Features

• High-Temperature Composite: Manufactured from a specialized heat-resistant polymer that prevents "flat-spotting" and ensures consistent shifting during long, high-speed rides.
• Nylon-Coated Outer Shell: Features a low-friction coating for a butter-smooth glide within the variator ramps, reducing parasitic drag and wear on your pulleys.
• Broad Tuning Range: Available in multiple gram weights (9G to 15G), allowing you to customize your RPM curve for big-bore kits or stock engine configurations.
• Precision Balanced: Each weight is calibrated to ensure balanced centrifugal force, reducing vibration and extending the life of your crankshaft bearings.

Mechanic's Note: Tuning your rollers is the cheapest way to change how your scooter feels.

Tuning Tip: Use lighter weights (9G-11G) for better hill climbing and faster take-offs. Use heavier weights (13G-15G) to lower your cruising RPMs and increase top speed.

Pro Tip: If you are running a Big Bore Kit, you will typically want to lean toward heavier rollers to take advantage of the increased torque!
