KTM 990 SUPERDUKE [2005-2021] - Z-ring chain

Discover the innovative and revolutionary Z-ring chain from Regina, specially developed for high performance and endurance (HPE). This chain sets new standards in the motorcycle industry by eliminating the need for regular lubrication every 1,000 km. Extensive laboratory and road testing has proven that the lifespan of the HPE chain is at least equivalent to, if not greater than, that of a traditional, regularly lubricated Z-ring chain.

A special feature of this chain is the coating with tetrahedral amorphous carbon (ta-C), one of the most advanced coatings among the DLC (Diamond Like Carbon) coatings. This coating is applied to the surface of the 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.

Eliminating the need to clean the chain and use lubricants not only minimizes maintenance, but also minimizes environmental impact. The innovative ta-C coating technology was developed through intensive research and development work by Regina engineers in Italy. With this chain you are relying on an environmentally friendly and low-maintenance solution that takes your driving experience to a new level.
