The RK Excel 520SO-130 drive chain is a traditional round O-ring chain designed for low- to mid-range displacement motorcycles equipped with sealed chains from the factory. Its durable steel construction and sealed lubrication system provide dependable power transfer for street riding, off-road use, and ATV applications up to 400 cc. The natural finish offers a practical appearance suited to everyday service and replacement needs.
RK Excel forms each SO-series O-ring from nitrile butadiene rubber to help retain internal lubrication while limiting seal-ring drag and horsepower loss. This design supports smooth operation, reduced maintenance, and consistent performance in demanding riding conditions. The 520SO-130 configuration includes a clip-type master link for convenient installation when properly matched to the motorcycle’s original chain specifications.
Fitment: The RK Excel 520SO-130 is suitable for compatible motorcycles and ATVs using a 520-size sealed drive chain with 130 links. It is rated for applications up to 400 cc and 60 horsepower, with suitability for both street and off-road use. Always confirm the required chain size, link count, clearance, and manufacturer fitment recommendations before installation. Manufacturer: RK Excel. Vendor part number: 520SO-130.
