The RK Excel GB420MXU2-130 is a premium gold 420-pitch drive chain designed for off-road motorcycles, small-displacement motorcycles, and other powersports applications. Built with RK’s U-Seal technology, this chain provides increased durability without adding unnecessary drag. The chain includes a clip-type master link for convenient installation and service.
RK’s UW-Ring sealing system uses triple-barrier grease protection and anti-debris technology to help prevent contaminants from creating friction between internal chain components. The U and UW seals also use reduced contact points to minimize cold-start drag. Their thinner profile compared with conventional O-ring seals supports smooth operation while helping extend chain service life.
With a 4,540-pound tensile strength, the RK Excel GB420MXU2-130 is rated for applications up to 150cc off-road and up to 35 horsepower. The 130-link configuration is suitable for compatible 420-pitch drive systems, provided the motorcycle or equipment manufacturer’s fitment requirements are met. Always confirm chain pitch, required link count, clearance, and master-link style before installation.
