Cam Chain

A chain running between the crankshaft and camshaft on overhead camshaft four stroke engines. This is often called a timing chain because it “times” the crankshaft to the camshaft so that the valves open and close at the proper time. Motorcycle cam chains can be a roller type (similar to the chain driving the rear wheel but much smaller) or a Hy Vo multi plate type. Other methods of connecting the crankshaft and camshaft are gear drive, shaft drive and toothed rubber belt drive.
