JZ511203 Motorcycle Moto Rocker Arm Assy For BAJAJ BOXER BM150

   The rocker arm assembly in a motorcycle engine is a crucial component of the valve train system. Its primary function is to actuate the opening and closing of the intake and exhaust valves in synchronization with the engine's combustion cycle.

    The rocker arm assembly is typically located on top of the cylinder head and is driven by the camshaft. It consists of rocker arms, which are pivoting levers, and associated components such as rocker arm shafts, adjusters, and retainers.

   When the camshaft rotates, the lobes on the camshaft lift the pushrod or directly act on the rocker arm, causing it to pivot. This pivoting motion transfers the camshaft's rotational movement to the valve, resulting in the opening and closing of the valve.
