APRILIA SHIVER 900 [2017-2021] - Z-ring chain

The Regina 525 HPE Z-ring chain with rivet link sets new standards in motorcycle technology. This high-performance chain does not require regular relubrication, which would be every 1,000 km. This represents a significant innovation that significantly reduces both time and effort for motorcyclists.

Extensive tests in the laboratory and on the road have proven that the service life of the HPE chain is at least equal to, if not longer than, that of a conventional, regularly lubricated Z-ring chain. A key advantage of this chain is the coating with tetrahedral amorphous carbon (ta-C), one of the most advanced coatings from the group of DLC (Diamond Like Carbon) coatings. This coating is applied to the surface of the chain's bushings and rollers and reduces energy losses while increasing efficiency in the secondary drive.

The combination of extremely high hardness of the coated surface and a low coefficient of friction leads to improved performance. Additionally, eliminating the need for chain cleaning and preventing lubricant splashes during operation minimizes environmental impact. The innovative ta-C coating technology was developed through intensive research and development work by Regina engineers in Italy.

This advanced chain is an ideal choice for motorcyclists who value durability, performance and environmental friendliness.
