EK/PBR 520MRD7 13/51-116 Chain Kit - Standard Sprocket by EK CHAIN: a transmission kit designed for motocross, comprising a 520 MRD7 chain and a standard aluminium sprocket. Ideal for riders looking for a set that meets the demands of the terrain while retaining the original equipment.
The aluminium sprocket slightly reduces unsprung mass, useful for maintaining agility and handling on rough terrain. The MRD7 chain, suitable for pitch 520, offers a robust design adapted to the demands of off-road riding. The kit includes 116 links, allowing for cutting and riveting according to the motorcycle's assembly and model.
Compatible notably with Kawasaki KX 250 (2024 to 2026 models), this kit is aimed at motocross riders who wish to renew their transmission with standard and proven components. Before installation, check the alignment, tension, and type of rivet required by your motorcycle.
