The Desmosedici was Ducati's MotoGP racer, a V4 with four valves per cylinder (essentially two V-twins side by side), chosen over a super-twin that would have needed to rev beyond 17,000 rpm. Introduced in 2003 as the GP3, the 2004 GP4 was heavily revised and took much of the season to become competitive, with Loris Capirossi and Troy Bayliss both reaching podiums. It laid the groundwork for the later road-going Desmosedici RR.
