Renthal O-Ring 520 R3 Heavy Duty Enduro Chain Rieju MR250 MR300 Ranger

This new chain design does away with the "O-ring" and instead incorporates Renthal's SRS (Self-Regulating Seals) ring system to increase chain longevity. Chain has been upgraded to the R4 ranges proven quad riveting manufacturing process. Rivet link has also been changed to a hollow end to facilitate easier installation that does not require a Quad Stake Rivet tool to install. High-carbon alloy steel pins, solid bushings and rollers, and shot peening of plates and rollers for increased fatigue resistance.

Clip type and rivet link included.
