The RK EXCEL GB520MXU-CL is a gold clip-type master link designed for RK MXU 520 motorcycle chains. It provides a secure replacement connection for chain maintenance, repair, or custom chain assembly applications. This master link is engineered for motorcycles and off-road bikes using a 520-pitch chain, with fitment focused on applications rated up to 500cc off-road and 70 horsepower.
RK’s MXU chain system uses ultra-thin UW seals for motorcycles with narrow chain-clearance requirements. The UW-Ring seal design provides triple-barrier grease protection and anti-debris technology to help reduce friction between internal chain components and extend wear life compared with a non-sealed chain. Reduced seal contact points also help minimize drag during cold starts, while the thinner seal profile supports improved clearance in compact installations.
Fitment: Compatible with RK MXU 520-pitch chain applications when a clip-type master link is specified. Verify chain series, pitch, width, and master-link style before installation. The RK EXCEL GB520MXU-CL is supplied as a clip-type master link and is intended for proper installation with compatible RK chain components.
