EK/PBR 520M3 13/51 chain kit specially designed for motocross: a robust transmission finished in gold to equip your machine for track or off-road riding. This kit includes a chain with 116 links and a sprocket/crown ratio of 13/51 (standard crown), suitable for the demands of motocross where abrasion and load variations are common.

As with any transmission, regular lubrication and proper tension adjustment are recommended to maintain performance and longevity of the kit.
