CZ Chains, Kedja RDO, 118 Länkar, O-Ring, Enduro, 520

CZ 520 RDO:
Motorcycle chain designed for off-road use in difficult conditions. The special inner plate hole removes mud from the contact point between chain and sprocket, ensuring no dirt remains in the chain. Another advantage of the proposed inner plate is the straight shape. That very significantly reduces the friction loss of plate material during abrasion when moving on dirty chain guides.
