REGINA 520 ZRE Z-Ring is a high-performance sealed drive chain built for long wear and consistent power transfer. Its patented Z44 Z-ring design helps maintain sealing performance over time while improving flexibility.
Highlight the main advantage: The REGINA 520 ZRE Z-Ring Chain is designed for riders who want dependable power transfer with extended service life. Thanks to its patented Z44 Z-ring seal, it helps keep lubrication in and dirt out, supporting smoother operation and reduced wear over time.
How it improves your ride: In harsh motocross and enduro conditions, chains are constantly exposed to mud, sand and shock loads. The Z-ring flexes when assembled, creating a spring effect that helps the seal maintain its performance long-term, while also enhancing chain flexibility for more efficient drivetrain movement.
