TRIUMPH BONNEVILLE 865 [2006-2021] - Z-ring chain

The Regina 525 HPE Z-Ring chain with Rivet Link sets new standards in motorcycle technology. This state-of-the-art chain eliminates the need for regular relubrication that motorcyclists typically have to do every 1,000 km. Extensive laboratory and road testing has proven that the lifespan of the HPE chain is at least equivalent to, if not longer than, that of a traditional, regularly lubricated Z-ring chain.

An outstanding feature of this chain is the coating with hydrogen-free 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 extremely high hardness of the coated surface combined with a low coefficient of friction results in improved performance and longevity.

The innovative ta-C coating, developed through intensive research and development work by Regina engineers in Italy, not only minimizes maintenance costs, but also environmental impact, as there is no need to clean the chain or spray lubricants during operation. These technological advances make the Regina 525 HPE Z-Ring Chain an ideal choice for motorcyclists who value performance, efficiency and sustainability.
