The RK EXCEL 520SO-116 is a traditional round O-ring drive chain designed for low- to mid-range displacement motorcycles and ATVs. Built in the 520 chain size with 116 links, this steel chain is suitable for street and off-road applications up to 400cc when the vehicle was originally equipped with a sealed chain. Its natural finish provides a practical, durable solution for everyday replacement and maintenance needs.
The RK EXCEL 520SO uses O-rings made from nitrile butadiene rubber to help retain factory-applied lubrication between the pins and bushings. This construction supports smooth power delivery while reducing friction, seal drag, and lubricant loss. With a rated tensile strength of 6,900 pounds and support for applications producing up to 60 horsepower, the chain is well suited to compatible motorcycles and ATVs used for commuting, recreational riding, and moderate off-road operation.
Installation is supported by the included clip-style master link. Verify that your motorcycle or ATV requires a 520-size, 116-link sealed chain and confirm the manufacturer's fitment specifications before installation. The RK EXCEL manufacturer part number is 520SO-116, and the vendor part number is also 520SO-116.
