EK CHAIN 520MRD7 chain kit with a 13-tooth sprocket and ultra-light 49-tooth rear sprocket, specially developed for the motocross world. Gold chain matched with a lightweight aluminum sprocket: a combo designed to reduce unsprung mass and withstand the rigors of the tracks while minimizing friction between links. Ideal for riders seeking a reliable and lightweight transmission on demanding terrains.
Designed to withstand the traction and abrasion encountered in competition, this chain is aimed at motocross and enduro riders who want a solid transmission without sacrificing weight. Before installation, check compatibility with your motorcycle (e.g., Honda CR 250 R ME03 1992–1993) and ensure proper tension/alignment adjustment to guarantee even wear of the links and sprocket.
