PARTS UNLIMITED 520 O-Ring Series - Drive Chain - 104 Links MPU520POX104L2

A worn or inadequate drive chain is a reliability bottleneck that can leave you stranded or cost you a race. The PARTS UNLIMITED 520 O-Ring Series delivers the durability and consistent power transfer your high-performance build demands, with proven wear resistance that outlasts standard chains by over a decade. If your motorcycle originally came equipped with O-ring seals, this chain is engineered to match that design while pushing longevity further.

Built with quad-pin riveting, solid bushings, and rollers sealed by tough O-ring technology, this chain handles sustained throttle abuse without compromise. Shot-peening and factory pre-stretching eliminate break-in guesswork, so you're ready for immediate duty.
