Motorcycle drive chain by DID. The chain connects the front and rear sprockets and through it the movement is transferred from the engine (front sprocket) to the rear wheel (rear sprocket). 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
