Newfren produces a complete range of clutches with regard to applications and materials. The catalogue has products for models ranging from the old 1946 Vespa 98 to the latest competition MXGP and Moto3, including single-disc dry clutches for BMW, from 1969 onward, and special clutch plates for Speedway. It is, between clutch plates and centrifugal clutches, one of the widest ranges on the market. Newfren use an extensive range of organic and sintered friction materials developed for specific applications. The metal plates are made of special steels which are treated to maximize performance

Newfren has been chosen by Ducati as OE on the Panigale V4R with STM clutch system and is a partner of Ducati Corse and SBK team, and is nowadays the widest and most technologically advanced aftermarket range. The range includes organic and sintered plates for both wet and dry clutches. Both the sintered range and the organic range are high-performance products. Newfren clutch plates have also been chosen to supply Ducati production models.

The Newfren range of single-disc dry clutches provides applications for BMW from the 1970s onward, as well as Moto Guzzi and three-wheeled Piaggio, with a high-performance replacement. The original K type, available for all applications, is a high-quality replacement. The more recent KW type incorporates a new friction material composed of a synthetic aramid fiber, of which the main characteristic is its exceptional mechanical resistance to tension and heat. In the event of overheating the material will not suffer glazing and will return to its original characteristics as soon as it cools down. Another important feature of the new type is that its friction material is efficient even if it comes into contact with ”oil”. These are “High Quality Spare Parts”, ”Made in Italy”.
