YAMAHA DT 250 [1977-1982] - Z-ring chain

The Regina 525 HPE Z-Ring chain with Rivet Link sets new standards in motorcycle technology. This high-performance chain eliminates the need for regular lubrication that motorcyclists typically have to do every 1,000 km. Thanks to its innovative construction and the use of the advanced Tetrahedral Amorphous Carbon (ta-C) coating, it offers a service life that is at least as long as that of a conventionally lubricated Z-ring chain.

The ta-C coating, one of the most advanced DLC (Diamond Like Carbon) coatings, is applied to the surface of the chain's bushings and rollers. This coating reduces energy losses and increases efficiency in the secondary drive by combining extremely high hardness of the coated surface with a low coefficient of friction. These features result in improved chain performance and longevity.

Another advantage of the Regina 525 HPE Z-Ring chain is the reduction of environmental impact. Eliminating the need to clean the chain and use lubricants significantly minimizes environmental impact. The development of this innovative coating technology is the result of intensive research and development work by Regina engineers in Italy. This chain is ideal for motorcyclists who value performance, efficiency and environmental protection.
