NCY 18x14mm Roller Weights | GY6 Genuine Buddy Kymco SYM

Description

Precision-tune your CVT with NCY 18x14mm roller weights. Available in 8g–13g to dial in quicker acceleration or higher top speed. Set of 6. Replaces flat-spotted stock rollers to restore smooth shifting and peak performance on GY6 150cc engines, Genuine Buddy series, Kymco, SYM, and Lance scooters.

Tuning guide:

• Lighter (8g–11g): higher RPMs, faster take-off, better hill climbing — ideal for city riding
• Heavier (12g–13g): lower cruising RPMs, better fuel economy, higher top speed on flat roads
• To create a half-gram setting (e.g., 10.5g), alternate three 10g and three 11g weights in the variator
• Always install in an alternating 120° pattern to prevent vibration or damage
• Inspect every 1,000 miles for flat spots
