Description
For mini racers pushing their machines to the limit, chain failure isn’t an option—it’s a catastrophe. The Renthal 420 R1 Works Chain delivers the tensile strength and wear resistance needed to handle the demands of high-RPM, high-impact riding without sacrificing reliability. Built with shot-peened alloy steel side plates and chromized pins, this chain maintains consistent power delivery lap after lap while resisting the corrosion and wear that shorten chain life on off-road machines.
Whether you’re racing a 2-stroke or 4-stroke mini, this 120-link chain integrates seamlessly with Renthal sprockets and installs in minutes with the included clip-type master link. No special tools, no complications—just bolt-on performance you can trust.
