Designed for the demands of motocross, this chain kit combines the robustness of a standard steel sprocket with the golden finish of the EK chain. Ideal for riders tackling challenging terrains — dirt, mud, and jumps — it offers a reliable transmission link and controlled wear thanks to a design aimed at minimizing friction without claiming unverifiable gains.
