15x12 Dr. Pulley Sliding Roller Weights

Traditionally, the gear ratio in scooter CVTs is changed by the in-and-out rolling movement of the roller weights. With the innovative Dr. Pulley sliding roller weights, the roller weights "slide" inward and outward in the Movable Drive Pulley (MDF) to change/extend the gear ratio.

Dr. Pulley sliding roller weights provide the following advantages over traditional "rolling" roller weights:

Eliminate abnormal wear in the high gear position.

Enjoy a broader range of gear ratios.

Experience outstanding acceleration and re-acceleration properties.

Retain explosive low end acceleration and reach higher top speeds.

Last longer than traditional roller weights while experiencing excellent CVT variator performance.

U.S. patent no. 7276004.
