Standard Series Transmission Chain RK - Ref. 420SB-112-CL
Designed for off-road sessions, this RK Standard Series M420 chain is aimed at enduro and motocross riders looking for a robust and easy-to-maintain transmission. Made from medium carbon alloy steel, it incorporates industrial processes of heat treatment and shot peening to enhance the durability of components subjected to the stresses of the terrain.
Ideal for replacing an original chain on lightweight machines, it offers a classic and reliable construction suited to off-road demands. The reinforced riveting and shot peening reflect a commitment to trail durability, while the quick-release feature facilitates interventions on the track or in the workshop.
