Regina 520 ZSE Drive Chain, 118 Links (135ZSE/1003)

The REGINA 520 ZSE Drive Chain, Part 135ZSE/1003, is engineered for dependable power transmission in motorcycle and powersports applications. Built from high carbon alloy steel, this chain offers a strong, durable construction designed to withstand demanding operating conditions while supporting consistent performance over extended use. Its 118-link configuration provides a practical replacement solution for compatible drive systems.
The narrow Z-ring design helps reduce the chain’s overall width and minimizes articulation friction as the links move through the drive system. This design can support smoother operation, efficient movement, and reduced resistance compared with conventional sealing configurations. The chain is suited for applications requiring a balance of durability, flexibility, and reliable chain engagement.
Gold-colored outer plates provide a distinctive appearance while complementing the chain’s rugged construction. The REGINA 520 ZSE is a suitable choice for replacing a worn or damaged drive chain when the original equipment specifications call for a compatible 520-size chain with 118 links. Verify fitment, chain size, link count, and application requirements before installation to ensure proper compatibility and performance.
