NCY performance variator kit for the 2022+ Yamaha Zuma 125 (BWS 125). Replaces the stock variator with a lightweight CNC-machined drive face and PTFE-coated roller tracks for faster acceleration, smoother shifting, and improved top-end speed. Tuned specifically for Yamaha’s VVA (Variable Valve Actuation) engine.
Note: Roller weights are not included. We recommend 20x12mm 12g rollers to complete this kit.
