APRILIA DORSODURO 750 [2007-2020] - Z-ring chain

The Regina 525 HPE Z-Ring Chain with Rivet Link sets new standards in performance and durability for motorcycle chains. This highly developed chain does not require regular relubrication, which makes it particularly low-maintenance. Motorcyclists no longer have to lubricate the chain every 1,000 km, which not only saves time but also reduces maintenance costs.

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 conventional, regularly 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 efficiency in the secondary drive through the combination of extremely high hardness of the coated surface and a low coefficient of friction.

Another advantage of the Regina 525 HPE chain is the minimized environmental impact, as there is no need to clean the chain or spray lubricants during operation. The groundbreaking ta-C coating technology was developed through intensive research and development work by Regina engineers in Italy. This chain is an excellent choice for motorcyclists who value performance, durability and low maintenance.
