BMW S 1000 [2014-2025] - Z-ring chain

The Regina 525 HPE Z-ring chain with rivet link sets new standards in motorcycle technology. This advanced chain features innovative Z-ring technology that eliminates the need for regular lubrication that would otherwise be required every 1,000 km. This offers motorcyclists a significant advantage in terms of maintenance and handling.

Extensive testing in laboratories and on the road has 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 highlight 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 chain's 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. Additionally, eliminating the need to clean the chain and lubricant contamination during operation minimizes environmental impact. This technological innovation was made possible through intensive research and development work by Regina engineers in Italy.
