The Regina 525 ZRT drive chain is engineered for dependable performance, extended wear life, and consistent power transfer in demanding motorcycle applications. This 110-link chain uses Regina’s patented Z44 sealing rings to improve protection and reduce friction compared with conventional O-ring designs. The result is smoother operation, reduced power loss, and enhanced durability for street, touring, and performance-focused fitments that require a 525-size chain.
Special high-temperature grease remains sealed in the critical pin and bushing area to support continuous lubrication throughout the chain’s service life. High-carbon alloy pins help minimize wear, while increased roller thickness strengthens the chain’s contact surfaces. Thicker outer plates and quad-riveted construction provide improved tensile strength and reliable operation under load.
This Regina 525 ZRT model includes a rivet-type connecting link for installation. Verify that your motorcycle requires a 525 chain, uses 110 links, and is compatible with a rivet-style master link before installation. The manufacturer is Regina, the brand is Regina, and the manufacturer and vendor part number is 137ZRT/011. Proper alignment, tension, lubrication, and installation are recommended for maximum chain life and safe performance.
