RK's ZXW series is ideal for both racing and general use. ZXW features technology derived from the MotoGP and FIM Suzuka 8-hour Endurance and has proven superiority with its 35 first-place finishes out of 39 races at the FIM Suzuki 8-Hour Endurance Race.
RK's XW-Ring seals provide three contact lips and two lubrication pools to protect against dirt and debris, high-speed abrasion, heat build-up and the loss of lubricant under extreme conditions. That's a fancy way of saying XW-Ring seals make your chain last longer. When RK develops a chain with a combined heritage of both drag racing and extreme endurance racing, riders can rest assured that they're getting the best of both racing worlds.
