Motorcycle chain & sprocket set by MHQ. A chain and sprocket set, as it is commonly called, includes the chain and the two sprockets (front and rear) that are necessary to transfer the movement from the engine (front sprocket) to the rear wheel (rear sprocket).

It has 40 teeth, which means that it has this specific number of teeth on its perimeter. The pitch of the chain, which is 428, is the distance between its pins. This is indicated by the first digit of the above number, while the other two digits refer to the width and strength of the chain. See full description
