The RK Excel 520SO-CL is a clip-type master link designed for RK 520SO O-ring motorcycle chains. Built for low- to mid-range displacement motorcycles, this steel master link supports applications up to 400cc on the street or off-road, including compatible ATVs. It is intended for vehicles originally equipped with sealed chains and provides a practical replacement solution for chain service and maintenance.
The RK Excel 520SO chain uses a nitrile butadiene O-ring design to help retain lubrication between the chain components while reducing seal drag and power loss. The compatible chain is rated for up to 6,900 pounds of tensile strength and up to 60 horsepower, making the 520SO-CL suitable for everyday street riding, recreational off-road use, and other approved applications. The chain is available in a natural finish, and this master link is supplied in a durable steel construction for reliable installation when properly fitted.
Use the RK Excel 520SO-CL only with the corresponding RK 520SO chain and verify chain size, link style, and vehicle compatibility before installation. The clip-style master link is included as the service connection for the chain and should be installed according to the manufacturer’s procedures. Manufacturer part number: 520SO-CL.
