Sprockets are one of the components of a motorcycle paired with a chain that is used to tramit the rotating force from the engine to the rear wheel. On a motorized bicycle, combustion in the engine produces rotation which is forwarded by the clutch from the drive shaft to the forward shaft. The sprocket and chain function as a power trafer (rotating power from the engine to the rear wheel), so that the motor can work optimally.
