Renthal R1 420 Works Chain

The Renthal R1 420 Works Chain is built for today’s high-powered mini racing machines, offering premium strength, durability, and smooth power transfer in a compact 420 chain size. Designed as a mini version of Renthal’s trusted 520 R1 chain, this chain is a great match for mini moto and electric mini builds that need reliable drivetrain performance.

Built with shot-peened alloy steel side plates and chromised bearing pins, the R1 420 Works Chain is made to resist wear and handle hard riding. Pre-formed bushings help distribute power loads evenly, improving chain life and consistency under acceleration.

With an ultra-high 4,609 lb. average tensile strength, gold-colored side plates, copper-colored rollers, and an included clip-style master link, this chain delivers both performance and a clean factory look.
