The Regina 520 ZRE Z-Ring Drive Chain is a high-performance chain designed for dependable power transmission in demanding motorcycle and powersports applications. This 110-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 for consistent operation.
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 resistance to fatigue. The chain is pre-stretched to help improve initial performance and reduce adjustment requirements during break-in. It is supplied with both clip-type and rivet-type connecting links for installation flexibility, subject to the requirements of the specific application.
Use the Regina 520 ZRE as a replacement drive chain when the application requires a 520-size, 110-link chain. Verify motorcycle or vehicle fitment, chain length, sprocket compatibility, and the preferred connecting-link style before installation. This product is manufactured by Regina and identified by manufacturer part number 135ZRE/1003 and vendor part number 135ZRE/1003.
