The Ducati Desmosedici MotoGP bike has always been famous for its top speed, a characteristic which is generally put down to two things: the first is the 16-valve V4 desmodromic engine, the brainchild of Ducati Corse director Filippo Preziosi, which has long been the most powerful engine on the grid. The second factor is the Bologna company's focus on aerodynamics, an area that other factories have spent much less time and attention on. The extremely slippery nature of the Ducati Desmosedici is in large part due to Ducati Corse's use of former F1 engineer Alan Jenkins as an aerodynamics consultant.
Jenkins has worked ceaselessly with Ducati over the years to improve the aerodynamics of the Desmosedici, and the German Grand Prix at the Sachsenring saw a new innovation appear on the fairing of the bike. The Ducati had sprouted a pair of "winglets" (shown below) - protruberances sticking both forward and out of the side of the fairing, at about the height of bottom of the fork outer. Naturally, these strange additions aroused the curisoity of the assembled media, who set about trying to fathom their purpose.
