The APM Clutch Upgrade Kit enhances engagement by replacing the stock spring with a 15% stiffer diaphragm spring, ensuring more consistent clutch operation. This design incorporates an additional clutch plate to increase grab, resulting in a total configuration of nine friction plates and eight tempered steel drive plates. The kit is manufactured in the U.S.A. and features a pre-measured stack height, simplifying the installation process while maintaining precise mechanical tolerances.
This hard parts upgrade is engineered to improve power transfer efficiency through its reinforced spring rate and expanded plate count. By utilizing tempered steel for the drive plates, the kit provides durable performance suited for demanding riding conditions. The pre-measured stack height ensures proper alignment and function, allowing riders to benefit from the increased clutch grab without the need for complex adjustments during assembly.
