Chain and Sprocket Kit
DID 428 HD Heavy Duty Chain
As well as using solid bushing, which can last 1.2 to 4 times as long as chains without, DID's HD Heavy Duty chain features thicker plates than the standard chain, and its tensile strength is roughly 20% higher. As with all DID chains, it is made with the latest chain manufacturing technology by DID's experienced engineers in Japan, at the high quality DID is so renowned for.
All DID chains are made in Japan.

Nearly all motorcycles have a drive system comprising of two sprockets: a front sprocket (also known as the counter-shaft or drive sprocket) and a rear sprocket (also known as the driven sprocket).
The front sprocket is attached to the engines transmission output shaft with the rear sprocket mounted to the rear wheel. Both sprockets have teeth which slot into the gaps in the motorcycle's drive chain.
The sprockets work in tandem with their teeth engaging between the drive chain links. The front sprocket rotates at the same time as the engine's transmission output shaft, and the teeth pull the drive chain, in turn rotating the driven sprocket as it traverses. This system transfers the power from the engine to the rear wheel, moving the motorcycle forward.
This pulling force is transmitted via the side plates of the chain through the chain's pins to the rollers. The distance between the centres of the pins is equal to the distance between the centres of the sprocket teeth. This means that the force pulling the chain is equally distributed among the rollers.
