This chain is nothing less than a revolution. So far it’s been like this: anyone riding a motorcycle with a chain as secondary drive was forced to clean, grease and re-tension O-ring chains.

This innovative chain puts an end to this. With the new HPE Z-ring chain, all of the advantages of a chain drive are brought to bear for the first time without having to accept any of the negatives.

HPE stands for High Performance Endurance. And it improves the effectiveness of the drive so that more power is directed to the back wheel, or alternatively, consumption can be reduced.

Extensive lab and street testing demonstrate that the HPE chain has a useful life that is at least equivalent, if not greater, than a traditional regularly re-lubricated Z-Ring chain.
The hydrogen-free Tetrahedral Amorphous Carbon (ta-C) coating, currently considered as the most advanced among DLC (Diamond Like Carbon) coatings, is applied on the surface of the bushings and
rollers of the HPE chain. The ta-C coating reduces energy dissipation and increases efficiency in the secondary transmission, combining the very high hardness of the coated surface with a low coefficient of friction.

The elimination of chain cleaning and lubricant spatter during operation minimizes environmental impact.

The innovative ta-C coating process was developed through intense R&D activity of Regina engineers and is entirely carried out in thier Cernusco Lombardone (LC) plant in Italy.

“The elimination of the periodic re-lubrication and the greater efficiency of the transmission raise the HPE chain to an extremely advanced technological level compared to traditional sealed chains, unthinkable until today and unparalleled on the market;” said Paolo Garbagnati, CEO of Regina. “We would like to thank all the women and the men who made the achievement of this important goal possible, including all the passionate riders, who, confidentially and professionally, contributed to the project with many extensive test rides.”
