520 ZRE Z-Ring Chain

High-performance final-drive durability for demanding off-road use. The REGINA 520 ZRE Z-Ring chain is built for riders who want consistent power transfer, longer wear life, and dependable sealing in mud, dust, and harsh conditions. Its patented Z44 Z-Ring seal design flexes after assembly to create a spring effect, helping the seal maintain its effectiveness over time while improving chain flexibility.

Thanks to high-alloy steel plates and pins, solid bushings and rollers, plus shot-peened components and factory pre-stretching, this chain is designed to handle repeated heavy loads with reduced elongation—helping you keep gearing consistent and maintenance intervals more predictable.
