Aftermarket Minis Power Valve Spring - KTM 65 SX / GASGAS MC 65 / HUSQVARNA TC 65

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.
