Chain and Sprocket Kit

DID 520 VX3 Heavy Duty X-Ring Gold/Black Chain

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.
