Dr. Pulley Over-Range Variator Kit for Yamaha 2T Minarelli

Dr. Pulley Over-Range Variator Kit for Yamaha 2T Minarelli

This Dr. Pulley Over-Range Variator Kit is made to work with the Yamaha 2T Minarelli scooter and aims to boost its speed and acceleration. It suits riders who want more out of their machine. It belongs to the Minarelli 50cc / Yamaha jog scooter parts range and uses an extended gear ratio to help with quicker starts and higher top-end speed.

Larger Diameter for Greater Top Speed

The variator measures 94mm across the outside, which is noticeably bigger than standard units. The wider size gives the drive belt more contact area, which translates into higher speed at the top end. Its extended ramp shape is matched to high-performance sliding weights, offering smoother power delivery and fewer dead spots than the original parts.

Build Quality and Alignment

The variator is cast from high-strength alloy, which helps it shed heat well. Keeping temperatures under control helps the belt maintain grip, reducing slip when riding hard. Everything needed comes in the box: the variator boss, back plate, sliders, and precision spacers. These parts help the belt track correctly and keep alignment accurate for the best results.
