Renthal – R1 428 Works Chains
When strength, speed, and precision matter most, the Renthal R1 Works Chain is the racer’s choice. Engineered to take the brutal punishment of off-road competition, this premium non-O-ring chain delivers maximum power transfer with minimal weight—perfect for riders chasing every ounce of performance.
Built from shot-peened alloy steel side plates and chromised bearing pins, the R1 chain laughs off impact loads and resists wear even in the harshest conditions. Extended bushings cut down friction for a smoother, faster ride, while chamfered inner links reduce the risk of derailment when the track gets rough. With an ultra-high tensile strength of 4,496 lbs, gold-finished side plates for corrosion resistance, and a clip-type link included for easy installation, this chain is all about uncompromising durability and race-ready performance.
The Renthal R1 Works Chain isn’t just a component—it’s the link between raw engine power and your drive to win.
