REGINA 520 ZRT - Chain - 120 Links 135ZRT/1008

A chain is only as strong as its weakest link—and the REGINA 520 ZRT eliminates that weakness. Its patented Z44 sealing rings reduce friction by 50% compared to traditional O-ring designs, translating directly to smoother power delivery, less parasitic loss, and extended chain life. If you're running a street bike or superbike up to 1,300cc, this is the chain that keeps you connected to the pavement.

Built for serious riders who refuse compromises, the 520 ZRT features high-carbon alloy pins, thicker outer plates, and quad-riveting for maximum tensile strength. The sealed design maintains constant lubrication in the critical pin/bushing interface, dramatically reducing wear even under sustained high-RPM conditions. This is precision engineering that pays dividends in longevity and performance.
