Designed for motocross riders seeking a reliable replacement, this kit combines the sealed EK 420SH chain with a front sprocket and a rear sprocket made of PBR steel. The chain, without O-Ring, utilizes CRH-Pin technology: a hardened outer layer for strength and a softer inner layer to minimize wear. The result is a robust solution for the transmission of small displacement bikes and demanding terrains.
