DUCATI 797 MONSTER [2017-2020] - Z-ring chain

The Regina 525 HPE Z-Ring chain with Rivet Link sets new standards in motorcycle technology. This chain is characterized by its innovative Z-ring technology and a special High Performance Endurance (HPE) design, which makes regular lubrication unnecessary. Motorcyclists no longer have to lubricate the chain every 1,000 km, which offers 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. Another outstanding feature of this chain is the Tetrahedral Amorphous Carbon (ta-C) coating, one of the most advanced forms 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 very high hardness of the coated surface combined with a low coefficient of friction results in improved performance. Eliminating the need to clean the chain and prevent lubricant splashes during operation also minimizes environmental impact. These technological advances were made possible through intensive research and development work by Regina engineers in Italy.
