Show original supplier description

The NCY Roller Weights are precision-engineered 20x12mm components designed to fine-tune your scooter's continuously variable transmission (CVT) performance. These round roller weights are essential for optimizing acceleration and top-end speed by adjusting the transmission's engagement and shift points. Specifically designed for Yamaha Zuma 125 and Vino 125 models, these roller weights are available in a range of gram options (e.g., 9g, 10g, 11g, 12g, 13g, 14g, 15g). Selecting the appropriate weight allows riders to achieve a desired balance between quick off-the-line response and higher cruising speeds, catering to various riding styles and performance goals. The standard performance size of 20x12mm ensures compatibility with many performance variators. Properly tuning your CVT with the correct roller weights can lead to improved throttle response and a smoother overall riding experience. These weights are a common upgrade for riders seeking to extract the most performance from their Yamaha 125cc scooters.
