APRILIA DORSODURO 1200 [2011-2016] - Z-ring chain with rivet link

The Regina 525 HPE Z-Ring chain with Rivet Link sets new standards in motorcycle technology. 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 laboratory and road tests 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 this 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 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 and longevity. Additionally, eliminating the need for chain cleaning and preventing lubricant splashes during operation minimizes environmental impact. These technological advances were made possible through intensive research and development work by Regina engineers in Italy.
