Chaine de transmission EK CHAIN 520 RRS - Joints Nx-Ring - attache rapide type clip

By adopting the NX seal rings, a longer chain life is achieved for off-road and Supermoto racing. Holes are provided in the inner plate for maximum weight reduction. NX seal rings make chain width thinner than other chain to make more clearance between chain and the tire, especially for super moto racing use.
