PARTS UNLIMITED 520 O-Ring Series - Drive Chain - 96 Links MPU520POX96L2

A chain is only as strong as its ability to transfer power reliably, and a worn or undersized chain becomes your weakest link on the track or trail. The PARTS UNLIMITED 520 O-Ring Series delivers the durability and longevity you need through quad pin riveting, solid bushings, and factory-sealed O-ring design—engineered to outlast standard chains by a significant margin. If you're running a motorcycle originally equipped with O-ring chains, this Japanese-manufactured option is a direct replacement that demands less frequent maintenance and provides measurable gains in chain life.
