The Regina 520 ZRE Z-Ring Drive Chain is a high-performance chain designed for demanding motorcycle and powersports applications. This 114-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 maintain sealing performance over time while also supporting smooth chain articulation.
Built with high-alloy steel plates and pins, solid bushings and rollers, and shot-peened plates, pins, and rollers, the Regina 520 ZRE is engineered for durability and dependable power transfer. The chain is pre-stretched to enhance performance and reduce initial adjustment requirements. Its 520-size configuration makes it suitable for compatible motorcycle and powersports drivetrain applications; verify the manufacturer’s fitment specifications before installation.
The Regina 520 ZRE includes both clip-type and rivet-type connecting links, providing installation flexibility for different service requirements. Manufactured by Regina, this chain is identified by manufacturer and vendor part number 135ZRE/1005. Proper installation, lubrication, and tension adjustment are essential for maximizing chain life and maintaining safe operation.
