One of RK Chain’s most popular ATV rated chain is the 520EXW. EXW is an XW-Ring sealed chain and is the best high-speed, extreme heat performance ATV chain available today. RK’s XW-Ring seals utilize triple barrier grease protection plus anti-debris technology. Anti-debris protection is vitally important to maximize chain wearlife by eliminating debris friction between internal components. EXW was designed to handle ATV swingarm movement and increased torque stresses and wears 10 times longer when compared to non-sealed chains. EXW chains also feature special thermal crack resistant sideplates to protect against thermal cracking. Thermal cracking can result from debris or components impinging the chain’s movement. The impingement causes the chain to quickly heat up and cool down in rapid succession. Over a period of time this thermal exposure can reduce the strength of the chain and/or cause a chain failure. It is vitally important to check your bike after a crash to make sure no debris or bike components are in contact with the chain.

Rated up to 750cc Applications: Dirt and ATV 520EXW is RK’s premium quality 520 XW-Ring chain. With a maximum tensile strength rated at 7,700 foot pounds and suitable up to 750cc ATV/Quads and Off-Road bikes, 520EXW can handle anything you dish out!
