BMW S 1000 [2021-2025] - Z-ring chain

The Regina 525 HPE Z-Ring Chain with Rivet Link sets new standards in motorcycle chain performance and durability. This highly developed chain does not require regular relubrication, which makes it particularly low-maintenance. Motorcyclists benefit from significant time and cost savings as the usual lubrication every 1,000 km is no longer necessary.

Extensive tests in the laboratory and on the road have 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. The innovative tetrahedral amorphous carbon (ta-C) coating, one of the most advanced DLC (Diamond Like Carbon) coatings, is applied to the bushings and rollers of the chain. This coating reduces energy losses and increases the efficiency of the secondary drive thanks to the extremely high hardness of the coated surface combined with a low coefficient of friction.

Another advantage of the Regina 525 HPE chain is the minimized environmental impact, as the usual cleaning and lubricant splashes are eliminated during operation. This technological innovation was made possible by intensive research and development work by Regina engineers in Italy. The chain is ideal for motorcyclists who value performance, efficiency and environmental protection.
