The RK Excel GB420MXU2-CL is a gold clip-type master link designed for RK Excel 420MXU2 sealed motorcycle and off-road chain. Built for 420 pitch applications, this replacement master link supports dependable chain assembly and maintenance while helping preserve the performance characteristics of the matching RK chain.
Featuring RK’s U-Seal design, the compatible 420MXU2 chain provides increased durability without excessive drag. Its UW-Ring sealing technology uses triple-barrier grease protection and anti-debris technology to help reduce friction caused by contaminants between internal chain components. The seal design also uses smaller contact points to help reduce cold-start drag, while the thinner U and UW rings support efficient operation and extended service life compared with conventional O-ring designs.
This RK Excel master link is intended for use with GB420MXU2 chain applications rated for off-road engines up to 150cc and 35 horsepower. The clip-style design allows convenient installation when properly matched to the chain and installed according to the motorcycle or chain manufacturer’s service instructions. Confirm that your chain is an RK Excel 420MXU2 model and that a clip-type master link is specified before installation. Manufacturer part number GB420MXU2-CL and vendor part number GB420MXU2-CL identify this gold replacement master link.
