KAWASAKI Z 900 [2017-2021] - Z-ring chain

The Regina 525 HPE Z-Ring Chain with Rivet Link sets new standards in motorcycle chain performance and durability. Thanks to its innovative design, this state-of-the-art chain no longer requires regular relubrication, which was previously required every 1,000 km. This not only saves time but also maintenance costs.

Extensive tests both 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 key advantage of the HPE chain is the coating with Tetrahedral Amorphous Carbon (ta-C), one of the most advanced coatings from the group 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 exceptional hardness of the coated surface combined with a low coefficient of friction results in improved performance and longevity. Additionally, eliminating the need for chain cleaning and lubricant application during operation helps minimize environmental impact. The development of this innovative coating technology is the result of intensive research and development work by Regina engineers in Italy.

The Regina 525 HPE Z-Ring chain is therefore an excellent choice for motorcyclists who value performance, efficiency and sustainability.
