DUCATI 749 [2003-2006] - Z-ring chain

The Regina 525 HPE Z-Ring chain with Rivet Link sets new standards in motorcycle technology. Thanks to its innovative design, this high-performance chain no longer requires regular relubrication, which was previously required every 1,000 km. Thanks to its advanced technology, Regina's Z-ring chain offers at least the same, if not longer, service life compared to traditional, regularly lubricated Z-ring chains.

A standout feature of this chain is the Tetrahedral Amorphous Carbon (ta-C) coating, 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 ensures a reduction in energy losses and increased 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.

The Regina 525 HPE Z-Ring Chain also minimizes environmental impact by eliminating the need for chain cleaning and eliminating lubricant splashes during operation. This innovative technology was developed through intensive research and development work by Regina engineers in Italy and represents a significant advance in motorcycle technology.
