About the Chain:
RK's EXW is an XW-Ring sealed chain and is the best high-speed, extreme heat performance ATV & Enduro 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 wear life by eliminating debris friction between internal components. EXW was designed to handle increased torque stresses and wears ten times longer when compared to non-sealed chains.
EXW chains also feature special thermal crack-resistant side plates 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.
