SUZUKI GSX R 750 [2006-2021] - Z-ring chain

The Regina 525 HPE Z-Ring Chain with Rivet Link sets new standards in the performance and durability of motorcycle chains. This innovative chain features High Performance Endurance (HPE) technology, which eliminates the need for regular relubrication, which is usually required every 1,000 km. This offers motorcyclists a significant advantage in terms of maintenance and handling.

Extensive tests in the laboratory and on the road have proven that the service life of the HPE chain is at least as long, if not longer, than that of a conventional, regularly lubricated Z-ring chain. A special feature of this chain is the coating with Tetrahedral Amorphous Carbon (ta-C), one of the most advanced forms of DLC (Diamond Like Carbon) coatings. This coating is applied to the surface of the bushings and rollers and reduces energy losses while increasing efficiency in the secondary drive.

The very high hardness of the coated surface combined with a low coefficient of friction results in improved performance. Additionally, eliminating the need for chain cleaning and lubrication during operation minimizes environmental impact. The development of this innovative coating process was carried out through intensive research and development work by Regina engineers in Italy.
