Product Details
ScootsUSA offers the best dr pulley sliders 20x12 yamaha zuma 125 vino 125 at great prices. Explore our catalog for top-quality parts and fast shipping! Dr. Pulley sliding roller weights are designed to automatically compensate for wear, enabling them to adjust outward within the movable drive pulley half, thereby facilitating a higher maximum vehicle speed. Traditionally, CVT gear ratio is altered through the vertical movement of roller weights along the ramp of the moveable drive face in the drive pulley / variator. However, the innovative Dr. Pulley Sliding Roller Weights utilize a sliding motion rather than a rolling one to modify the gear ratio. This distinct sliding action offers significant advantages that enhance CVT performance. With Dr. Pulley, there is no risk of abnormal wear, even under high gear conditions. Dr. Pulley's U. S. Patent Number 7,276,004, shows how Dr. Pulley roller weights effectively eliminate abnormal wear, prevent deterioration of the reduction gear ratio, extend the transmission's lifespan, and allow for adjustments in both reduction gear ratios and driving performance.
