The Dr. Pulley Over-Range Variator Kit optimizes the performance of your Yamaha 2T Minarelli scooter. This kit is engineered for enthusiasts seeking to improve speed and acceleration. It is one of the Minarelli 50cc / Yamaha jog scooter parts designed to extend the gear ratio, enabling quicker take-offs and improved top-end speed.

Increased Diameter for Higher Speeds

This variator features a 94mm outer diameter, significantly larger than standard variators. This increase in diameter allows for a larger surface area for the belt, resulting in higher velocity at top speeds. The extended ramp geometry is optimized for high-performance sliding weights, providing a smoother power delivery without the common dead spots found in original equipment parts.

Construction and Alignment

Constructed from a high-strength alloy, this variator is designed for efficient heat dissipation. This construction helps maintain friction levels, preventing belt slip during aggressive riding. The kit comes complete with the variator boss, backing plate, sliders, and precision spacers, ensuring proper alignment and belt tracking for peak performance.
