EK/PBR 520M3 13/50 Chain Kit - Ultra-Light Sprocket: a chain kit designed for motocross bikes, where weight, responsiveness, and longevity are essential criteria. This kit combines a robust 520 M3 chain with an ultra-light aluminum sprocket to minimize rotating mass and maintain the bike's agility on technical sections and jumps.

Designed for motocross/competition use, this kit prioritizes reducing friction and abrasion resistance on demanding terrains.
