Chain REGINA 525 HPE Z-ring + rivet link

Regina presents the innovative and revolutionary Z-Ring chain
High Performance Endurance (HPE)
which eliminates the periodic re-lubrication that motorcycle riders must perform every 1,000 km.
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 in Italy.
