Product Description

The Renthal 420 R1 Works Chain is a scaled mini version of Renthal's 520 R1 chain, specifically engineered for high-powered mini racing machines and off-road motorcycles.

Constructed with shot-peened alloy steel side plates, this chain offers an average tensile strength of 4,601 lbs. Chromised bearing pins resist severe wear in harsh conditions, while pre-formed bushings distribute heavy power loads evenly across the pins.
