Regina 520 ZRP Drive Chain, 120 Links (135ZRP/00E)

The Regina 520 ZRP drive chain is engineered for dependable power transmission, long service life, and reduced friction in demanding motorcycle and powersports applications. Part number 135ZRP/00E features Regina’s patented Z44 sealing rings, designed to improve sealing performance and wear resistance compared with conventional O-ring chains and earlier X-ring and Z-ring designs. The result is smoother operation and enhanced durability over extended use.
Special high-temperature grease provides continuous lubrication in the critical pin and bushing area, helping reduce friction and protect internal components during operation. Compared with traditional O-ring chains, the Regina ZRP design delivers up to 50% lower friction, supporting efficient power transfer while helping minimize heat and wear. High-carbon alloy pins further reduce elongation and wear, while thicker rollers are built to withstand repeated loading.
The chain also uses thicker outer plates and quad-riveted construction to increase tensile strength and improve resistance to demanding riding conditions. This 120-link Regina 520 chain includes a rivet-type connecting link for secure installation when properly assembled with the recommended tools and procedures. It is a practical replacement choice for riders and technicians seeking a durable, low-friction drive chain from Regina.
Designed for applications requiring a 520-size chain, the Regina 135ZRP/00E combines advanced sealing technology, robust materials, and factory-applied lubrication in a service-ready package. Always verify vehicle fitment, chain length, and connecting-link installation requirements before installation.
