Upgrade your motorcycle drivetrain with the RK-XW Sealed Chain and premium sprocket kit, engineered for maximum durability, performance, and reliability. The RK ZXW Series is RK’s flagship chain range, developed to meet the demands of modern superbikes and hyperbikes with exceptional tensile strength, rigidity, and instant throttle response.
Featuring advanced XW-Ring seal technology, the chain incorporates two lubrication pools and three contact lips to create a triple-barrier sealing system that locks in lubrication while preventing dirt and debris from entering. Designed for hypersport, road racing, and general street use, the ZXW Series delivers outstanding wear resistance, extended service life, and smooth power transfer.
RK offers five types of sealed-ring chains, each developed for specific riding conditions. The innovative XW seal significantly improves chain longevity and performance, while the ultra-thin U-Ring and UW-Ring designs provide enhanced rotating efficiency for specialised racing applications.
