520 R1 Works Chain

The Renthal 520 R1 Works Chain is built for riders who demand maximum performance from their final drive. This premium non-sealed (non-O-ring) race chain is engineered to be strong, lightweight, and efficient—helping your bike deliver power to the rear wheel with minimal drag. It’s a go-to choice when every detail matters, from starts to sprints and full race motos.

Thanks to extended bushings and precision construction, the chain reduces friction and improves power transmission, while chamfered inner links help lower the risk of derailment under aggressive riding. Chromised bearing pins boost wear resistance—especially valuable in off-road conditions—while gold-colored side plates help reduce corrosion and keep the chain looking sharp.
