"In the category of Valves and Rockers, Rocker Arms"

The rocker arm shaft is a component that supports and pivots the rocker arms within the motorcycle’s engine. Mounted securely to the cylinder head or engine block, it serves as the central axis around which the rocker arms rotate. As the camshaft drives the rocker arms, the shaft ensures their smooth, precise movement, allowing them to effectively open and close the engine’s valves.
