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.\u003c\/p\u003e\u003cp\u003eSpecial 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.\u003c\/p\u003e\u003cp\u003eThe REGINA 520 ZRT is an appropriate replacement drive chain for compatible street bikes and superbikes requiring a 520-size, 120-link chain.
