Designed by EK CHAIN for the motocross world, this 520MRD7 kit combines a 520 chain and a 13/50 sprocket/crown set suitable for off-road motorcycles. Its Gold/Gold color gives it a racing look while remaining discreet on the track. Ideal for riders looking for a durable and lightweight setup for their transmission.
