EK/PBR 420SH 12/47 Chain Kit – Standard Sprocket
Replace your worn transmission with a complete kit designed to last on urban small-displacement motorcycles. This kit combines the sealed EK 420SH chain with a front sprocket and a rear sprocket made of PBR steel (configuration 12/47), offering a robust and ready-to-install solution. The EK 420SH chain utilizes CRH-Pin technology: surface wear removal and internal flexibility for increased strength without an O-ring.
Ideal for urban and road use on small-displacement motorcycles, this kit prioritizes longevity and reliability of the transmission without frills. Be sure to check the number of links and the pitch of your motorcycle before installation. For optimal maintenance, regularly check the tension and lubrication compatible with sealed chains.
