APRILIA SRV 850 [2013-2021] - Z-ring chain

The Regina 525 HPE Z-ring chain with rivet link sets new standards in motorcycle technology. This high-performance chain eliminates the need for regular relubrication that motorcyclists typically have to do every 1,000 km. Thanks to its advanced technology, the innovative Z-ring chain offers a service life that is at least as long as that of a conventionally lubricated Z-ring chain, if not longer.

A special feature of this chain is the coating with tetrahedral amorphous carbon (ta-C), one of the most advanced forms 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 extremely high hardness of the coated surface combined with a low coefficient of friction results in improved performance and longevity.

By eliminating the need for chain cleaning and the elimination of lubricant splashes during operation, environmental impact is also minimized. Developed through intensive research and development work by Regina engineers in Italy, this technological innovation offers motorcyclists an efficient and low-maintenance powertrain solution.
