O-ring chain, perfect for off road and on road motorcycles up to 650 cm³. The ideal choice for combining durability, strength and weight.

• High tensile strength O-ring chain, especially for offroad racing
• 520 Pitch
• Shot-peened alloy steel side plates, high tensile strength
• Extended bushings to reduce friction between outer and inner link plates, maximising power output
• Including clip lock and rivet lock

Not suitable for road bikes, which are converted to a 520 chain but originally are equipped with a larger and heavier chain.
