The Regina 525 ZRE is a high-performance gold drive chain designed for demanding motorcycle applications. This 120-link chain uses Regina’s patented Z44 seal Z-ring sections, which flex during assembly to create a spring effect that helps maintain sealing performance over time. The Z-ring design also supports smooth chain articulation and enhanced flexibility, helping the chain operate efficiently through repeated movement and changing loads.
Manufactured by Regina, the 525 ZRE features high-alloy steel plates and pins, solid bushings and rollers, and shot-peened plates, pins, and rollers for improved durability. The chain is pre-stretched to help reduce initial adjustment requirements and enhance performance during service. A clip-type connecting link is included for installation, making this chain suitable for compatible motorcycle final-drive applications requiring a Regina 525-series chain with 120 links.
Finished in gold, the Regina 525 ZRE combines functional performance with a distinctive appearance. Confirm your motorcycle’s chain size, required link count, and manufacturer fitment specifications before installation. This product is identified by Regina manufacturer part number 137ZRE/016 and vendor part number 137ZRE/016.
