Dr. Pulley Performance Variator for Yamaha Zuma 125 / Vino 125

Dr. Pulley Performance Variator for Yamaha 125cc Scooters

This Dr. Pulley performance variator is made for 125cc Yamaha scooters, among them the Zuma 125, Vino 125, and Cygnus 125. Compared with the stock unit, it offers a wider gear range and smoother shifting. Riders looking to upgrade often pick it from the Yamaha Zuma scooter parts range. The kit also uses advanced cooling design to help protect the drivetrain over time.

Cooling Design

Both sheaves carry purpose-built cooling vanes that draw heat away during use. Keeping the belt cooler helps it last longer, which makes this a worthwhile update for riders who focus on performance.

Precision Engineering

Ramp angles are tuned specifically for the continuously variable transmission found in Yamaha's 125cc models. A snug fit reduces vibration and drag at higher RPMs, which supports better engine efficiency and quicker response, giving a more engaging ride.
