APRILIA TUONO 1100 [2015-2020] - Z-ring chain

The Regina 525 HPE Z-ring chain with rivet link sets new standards in the performance and durability of motorcycle chains. This sophisticated chain does not require regular relubrication, which would be every 1,000 km. This represents a significant improvement over traditional Z-ring chains that require regular lubrication.

Extensive testing in the laboratory and on the road has proven that the HPE chain lasts at least as long, if not longer, than conventional, regularly lubricated Z-ring chains. A key advantage of the HPE 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 chain's bushings and rollers and reduces energy losses while increasing efficiency in the secondary drive. The extremely hard coating combined with a low coefficient of friction results in improved performance.

Another significant advantage of the Regina 525 HPE chain is the minimization of environmental impact by eliminating the need for chain cleaning and lubricant spraying during operation. Developed through the intensive research and development work of Regina engineers in Italy, this innovative technology offers motorcyclists an efficient and low-maintenance powertrain solution.
