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 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 used its camshafts to both open and close the engine's valves, eliminating the usual valve closing springs, a system 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.
Designed by Massimo Tamburini and Sergio Robbiano and his team at the Cagiva Research Centre in San Marino, the 916's water-cooled engine was a revision of that of its predecessor, the 888, with larger displacement and a new engine management system. The greater displacement was accomplished by increasing the crankshaft stroke from 64 mm to 66 mm, keeping the same 94 mm bore size as the 888, resulting in a capacity of 916 cc. (By the time the 916 was introduced, the final 851/888 Corse engines had also had their bore sizes increased to 96 mm resulting in 'race only' capacities of 926 cc and 955 cc respectively.)
Ducati won 4 Superbike World Championships with the 916, in 1994–1996, and in 1998, with riders Carl Fogarty and Troy Corser.
