YAMAHA TRX 850 [1996-2000] - Z-ring chain

The Regina 525 HPE Z-Ring chain sets new standards in performance and durability for motorcyclists. Thanks to the revolutionary Z-ring technology, this innovative chain no longer requires regular relubrication, which was previously required every 1,000 km. The HPE (High Performance Endurance) chain has been proven through extensive laboratory and road testing to offer a service life that is at least as long, if not longer, than traditional, regularly lubricated Z-ring chains.

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 is characterized by a very high hardness and a low coefficient of friction. This reduces energy distribution and increases efficiency in the secondary drive.

The ta-C coating not only helps increase performance, but also minimizes environmental impact by eliminating the need for chain cleaning and lubricant splashing during operation. This technological innovation was driven by intensive research and development work by Regina engineers in Italy, making the HPE chain an excellent choice for environmentally conscious drivers and those who value low maintenance.
