Rocker Arm

Technology / Motorcycle / Rocker Arm: A centrally pivoted lever that transmits the motion of the camshaft to open and close the valves. MORE

Pushrods

Technology / Motorcycle / Pushrods: Pushrods are used to connect to rocker arm assemblies which, in turn, open and close valves. In this case, the Camshaft is located near the crankshaft. The rotation of the camshaft causes its lobes to MORE
