DID's VX3 Chain uses patented low-friction X-ring seals, which keep lubrication and dirt out. They provide superior protection against dirt than an O-ring chain while producing less friction and thus less power loss.

DID's X-ring chains have 40% greater wear resistance than DID's O-ring chain and 25 times that of the DID standard chain. With the correct maintenance, an X-ring chain will last longer than an O-ring or unsealed chain.

DID's VX3 chains feature new 'Direct Energy Transfer', which provides excellent throttle response due to an increased chain rigidity.

JT Sprockets

JT is the best selling aftermarket sprocket in the world. Using the finest raw materials and cutting-edge technology in production, CNC computer design and precision machining, JT ensures maximum durability and performance.

JT front sprockets are made with SCM420 chromoly steel alloy, while the rear sprocket is manufactured with ultra-durable high-carbon C49 steel.

Fitment and Maintenance Advice

DID 520 VX3 drive chains are always supplied 'open' with a rivet link (included). You will need a specialised tool in order to rivet the chain, or take it to a mechanic who can do it for you. A spring link is available, but a spring link has only 65% of the strength of a rivet link and therefore, a rivet link is always recommended.
It is important to periodically inspect and lubricate the chain to maximise chain life.

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).

motorcycle chain and 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.
