The Regina 525 ZRP drive chain is engineered for street bikes and superbikes with engines up to 1,300cc. This gold-finished chain includes 120 links and a rivet-type master link for secure installation. Manufacturer part number 137ZRP/00F and vendor part number 137ZRP/00F identify this Regina replacement chain for compatible motorcycle applications.
Patented Z44 sealing rings help reduce friction and improve resistance to wear compared with traditional O-ring chain designs. Special high-temperature grease remains concentrated in the critical pin and bushing areas, supporting smooth operation and extended service life. High-carbon alloy pins help minimize wear, while increased roller thickness improves durability during demanding street and performance riding.
Feature: Thicker outer plates and quad-riveting increase tensile strength and help the chain withstand the loads produced by high-performance motorcycles. The 525 chain configuration and 120-link length make it suitable for applications requiring this specific fitment; always verify the motorcycle model, year, original chain specification, and required final-drive length before installation. The included rivet-type link should be installed using the proper chain riveting tool and manufacturer-recommended procedure.
