Dr. Pulley Performance Variator - Yamaha Zuma 125 / Vino 125
Description
This Dr. Pulley performance variator kit is the direct-fit performance upgrade for Yamaha Zuma 125 (BWS), Vino 125, and Cygnus 125 scooters. Optimized ramp angles deliver a wider gear range and smoother, more aggressive shifting than stock, and precision-machined fan-fin cooling vanes on both sheaves reduce belt temperature to extend drivetrain life. The kit includes the assembled drive face, fixed sheave, movable sheave with sliding weight ramps and tan plastic guides, and steel boss/spacer tube. ISO 9001 manufactured in Taiwan. Sliding weights sold separately.
Note: Sliding weights are not included. Pair with Dr. Pulley 20x12 Sliding Weights to take full advantage of the ramp geometry.
