Ride faster with less drivetrain loss. The Renthal 520 R1 Works Chain is engineered for riders who demand maximum power transfer, high strength, and low weight in motocross and off-road racing. As a premium non‑O‑ring (non-sealed) chain, it’s designed to reduce friction and keep throttle response sharp—ideal when every horsepower and every second counts.
Built with shot-peened alloy steel side plates and chromised bearing pins, the R1 Works chain is made to handle aggressive riding and challenging conditions while resisting wear. Features like chamfered inner links help reduce the chance of chain derailment, and extended bushings reduce friction for smoother, more efficient power transmission. The gold-colored side plates also help reduce corrosion for a cleaner, longer-lasting finish.
