Description
Overview
Transform the way your 65cc bike delivers power with the Aftermarket Minis Progressive Power Valve Spring. Designed to eliminate the harsh power surge of the OEM single-rate spring, this progressive spring opens the valve more gradually, resulting in smoother low-end response, stronger mid-range pull, and better throttle control across the board. It’s a simple upgrade with a major impact on rideability and performance.
