Regina 520 ZRT Touring Street Series Chain - 120 Links

The Regina 520 ZRT drive chain (135ZRT/1008) is a 120-link, high-performance street/superbike chain featuring patented Z44 Z-rings that cut friction by 50% versus traditional O-rings and deliver superior wear life. It retains constant lubrication via high‑temperature grease at the pin/bushing interface, uses high‑carbon alloy pins and thicker rollers for durability, and thicker outer plates with quad-riveting for higher tensile strength. Ideal for street bikes and superbikes up to 1,300 cc. Supplied in gold with a rivet-type master link; clip-type and hollow rivet links are also available.
