Standard Series Transmission Chain RK – Manufacturer Reference: 420SB-130-CL
Designed for urban and off-road use, this RK Standard chain (M420) is aimed at small to medium displacement bikes (90–125 cc). Its construction from medium carbon steel alloy and the heat treatment of its components make it a robust option for replacing a worn chain on roadsters, enduro, motocross, or quads.
This chain fits standard sprockets and crowns; check the length and number of links before installation. As with any transmission, precise tension adjustment, regular lubrication, and monitoring of sprocket wear will extend the lifespan of the entire system. RK product suitable for riders looking for a reliable quality/price ratio replacement part, without claims of unverified performance.
