Features
The RK Series RKM transmission chain (manufacturer's ref: 420SB-138-CL) is a standard non-O-ring chain dedicated to Enduro and Cross practices on small displacement bikes. Designed for sprocket-crown connections on 80 and 125 cc motorcycles, it comes in a natural finish and features 138 links for precise and reliable installation.
Construction: shot-peened links, solid rollers, and two-point axle riveting
Preparation: pre-tensioned and pre-stretched chains for even load distribution
Installation: quick clip attachment included for simplified fitting and maintenance
Usage: oriented for Enduro and Cross terrains, suitable for motorcycles without O-ring chains
The thermal treatment of the components and shot-peening increase the mechanical strength of the links and rollers without claiming unverified performance: it is a robust and simple choice to replace the original chain on small displacement bikes. Ideal for riders looking for a standard chain that is easy to install and maintain, ready to tackle the demands of off-road riding.
