HONDA XBR 500 [1987-1988] - Z-ring chain

The Regina 525 HPE Z-Ring Chain with Rivet Link sets new standards in motorcycle chain performance and durability. Thanks to its revolutionary technology, this advanced chain no longer requires regular relubrication, which was previously required every 1,000 km. This not only saves time but also maintenance costs.

Extensive testing in laboratories and on the road has proven that the durability of the HPE chain is at least as high, if not greater, than that of a conventional, regularly lubricated Z-ring chain. A special feature of this chain is the coating with Tetrahedral Amorphous Carbon (ta-C), one of the most advanced coatings in the DLC (Diamond Like Carbon) group. 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 makes the Regina 525 HPE Z-Ring chain an optimal choice for motorcyclists who value performance and environmental friendliness. Eliminating the need for chain cleaning and avoiding lubricant splashes during operation also minimizes environmental impact. This innovative chain was developed through intensive research and development work by Regina engineers in Italy and represents a new generation of motorcycle drive technology.
