Regina High Performance Endurance (525) 137 HPE X 120 Links

100% Made in Italy

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 their Cernusco Lombardone (LC) plant in Italy.
