The REGINA 520 ZRT drive chain is a high-performance chain designed for street motorcycles and superbikes with engines up to 1,300cc. This 120-link chain features REGINA’s patented Z44 sealing rings, engineered to improve sealing, reduce friction, and extend wear life compared with conventional O-ring chains and earlier X-ring or Z-ring designs. The chain is supplied with a rivet-type connecting link for secure installation.
Special high-temperature grease is retained in the critical pin and bushing area to provide continuous lubrication during operation. High-carbon alloy pins help minimize wear, while increased roller thickness supports long-term durability. Thicker outer plates and quad-riveted construction improve tensile strength for demanding street and sport-riding applications.
The REGINA 520 ZRT is an appropriate replacement drive chain for compatible street bikes and superbikes requiring a 520-size, 120-link chain. Confirm the motorcycle manufacturer’s specifications, required chain length, and connecting-link style before installation. Clip-type and hollow-rivet connecting links are also available separately; the hollow-rivet version is compatible with many chain tools. Manufacturer part number: 135ZRT/1008.
