The Regina 520 ZRE Z-Ring Drive Chain is a high-performance chain designed for demanding motorcycle and powersports applications. This 112-link chain uses Regina’s patented Z44 seal Z-ring sections to help retain lubrication and protect internal components from contamination. The Z-ring flexes during assembly to create a spring effect that helps the seal maintain its performance over time while also supporting smooth chain articulation.
Constructed from high-alloy steel, the Regina 520 ZRE features durable plates and pins, solid bushings and rollers, and shot-peened plates, pins, and rollers for improved strength and fatigue resistance. The chain is pre-stretched to help reduce initial elongation and support consistent performance during service. Its 520-size configuration is suitable for compatible motorcycle and powersports drive systems requiring a sealed, high-performance chain.
This Regina chain includes both clip-type and rivet-type master links for installation flexibility, allowing fitment according to the application and manufacturer’s service requirements. Confirm that the vehicle uses a 520 chain size and requires 112 links before installation. Regina manufacturer and vendor part number 135ZRE/1004 identifies this specific 520 ZRE chain configuration.
