Regina 520 ZRE Z-Ring Drive Chain, 112 Links (135ZRE/1004)

The REGINA 520 ZRE Z-Ring Drive Chain is engineered for high-performance motorcycle and powersports applications where dependable strength, flexibility, and long-term sealing are essential. Part Number 135ZRE/1004 includes a 112-link chain designed to deliver smooth power transfer and consistent operation under demanding riding conditions.
The patented Z44 seal uses Z-ring sections that flex during assembly, creating a spring effect that helps maintain sealing performance over time. This design also enhances chain flexibility, supporting smooth articulation across the sprockets while helping protect internal components from contamination and lubricant loss. The result is a durable drive chain suited for riders who expect reliable performance and extended service life.
Constructed from high-alloy steel, the chain features strong plates and pins, solid bushings and rollers, and shot-peened plates, pins, and rollers for improved fatigue resistance. The chain is pre-stretched to help reduce initial adjustment requirements and enhance performance during use. Both clip-type and rivet-type connecting links are included, providing installation flexibility for a range of applications.
Choose the REGINA 520 ZRE when you need a robust, sealed drive chain with advanced Z-ring technology and dependable construction. Its 112-link configuration and included connection options make Part Number 135ZRE/1004 a practical replacement for compatible motorcycle and powersports drivetrain systems.
