BMW HP 4 1000 [2013-2021] - 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 lubrication, which was previously required every 1,000 km. Extensive testing in the laboratory and on the road has proven that the service life of the HPE chain is at least as long, if not longer, than that of a conventionally lubricated Z-ring chain.

A standout feature of the HPE chain is the tetrahedral amorphous carbon (ta-C) coating, one of the most advanced forms of DLC (Diamond Like Carbon) coatings. This coating is applied to the surface of the bushings and rollers and leads to a reduction in energy losses and an increase in efficiency in the secondary drive. The extremely high hardness of the coated surface combined with a low coefficient of friction ensures optimal performance.

The innovative ta-C coating technology was developed through intensive research and development work by Regina engineers in Italy. The elimination of chain cleaning and lubricant splashes during operation also minimizes environmental impact. The Regina 525 HPE Z-Ring chain is an excellent choice for environmentally conscious drivers who value performance and durability.
