The Regina 520 ZRE Z-Ring Drive Chain is a high-performance chain designed for demanding motorcycle and powersports applications. This 120-link chain uses Regina’s patented Z44 seal Z-ring sections to help retain lubricant and protect internal components from contamination. When assembled, each Z-ring flexes to create a spring effect that helps maintain sealing performance over time while also supporting smooth chain movement and enhanced flexibility.
Manufactured by Regina and identified by manufacturer and vendor part number 135ZRE/1008, this drive chain features high-alloy steel plates and pins, solid bushings and rollers, and shot-peened plates, pins, and rollers for improved durability under load. The chain is pre-stretched to help reduce initial adjustment requirements and promote consistent performance during installation and service.
The Regina 520 ZRE chain is supplied in a 120-link configuration and includes both clip-type and rivet-type master links for installation flexibility. It is intended to fit applications that specify a Regina 520-size Z-ring chain with a 120-link length; always verify the motorcycle or vehicle manufacturer’s chain size, link count, and master-link requirements before installation. Proper alignment, lubrication, and adjustment are recommended for dependable service life.
