Transmission chain CZ 520 RDO (118 links) with O-Ring CZ520RDO-118
- CZ 520 RDO chains are specially designed for off-road difficult conditions (mud).
- This chain model has specially designed holes between the inner plates that remove mud from the point of contact between the chain and the sprockets.
- Another advantage of the inner plate is the straight shape. This significantly reduces the friction loss of the plate material during abrasion when the dirty chain passes through the guides.
