RKASM004 Description Rocker Arm Assembly 139QMA 139QMB
The rocker arm assembly is a crucial component of a motorcycle’s valvetrain, responsible for transferring motion from the camshaft to the engine's valves. It consists of rocker arms mounted on a shaft or supports, which pivot to push the valves open and closed as the camshaft rotates. The assembly ensures precise timing and movement of the valves, which is essential for proper engine operation and performance.
