Four Valves
The first development of the 916 model family can be traced back to the development of the four-valve Ducati engine, the Desmoquattro, through the development and racing of the earlier Pantah models, to the road-going 851 and 888 models.
The chief designer of Ducati motorcycles since the 1970s was the late Fabio Taglioni (1920–2001). He introduced the Pantah in 1979; its engine was updated in the 1990s in the SuperSport (SS) series and all modern Ducati engines are derivatives of the Pantah, which employed a set of revolving cams to actuate the engine's valves (eliminating valve springs), called desmodromic. Taglioni, did not, however, have an interest in four-valve head engines, and so this was left to his successor. The eight-valve V-twin was the work of Taglioni's successor, Massimo Bordi.
