Ducati Desmosedici
Technical rules changed in 2002, giving priority to four-stroke machinery and turning the 500 class of World Road Racing into the MotoGP Championship.A twin would have had to rev at over 17,000 rpm, but this would require a very short stroke and a very large bore, as a result producing possible combustion problems.The basis of the Desmosedici engine design is a V4 configuration; essentially two classic V-twins mounted side-by-side, with two-cylinder stroking at the same time (also called Twin Pulse).Vittoriano Guareschi, the Ducati Corse test-rider, followed every phase of the Desmosedici's development process from early testing to track debut and the project's evolution.In early 2021, Ducati rider Johann Zarco set the highest trap speed record in competition practice on the Desmosedici.[1] While still fully committed to Superbike racing, the Ducati Marlboro Team of Loris Capirossi and Troy Bayliss would compete in all rounds of the 2003 MotoGP championship.The Desmosedici GP3 quickly scored a series of results with Loris Capirossi, who stepped onto the podium in the opening round of the championship in Japan and won the GP Catalunya in Barcelona.Capirossi took two wins in the Grand Prix of Japan at Motegi and in the Malaysian GP at Sepang, while Checa scored a brace of podium finishes.Involving better aerodynamics and a better fuel tank position, most importantly, although more powerful, the engine delivery was smoothened to make the bike more rideable.After encouraging winter tests, the Desmosedici GP6 took its first win of 2006 in the opening GP at Jerez de la Frontera, Spain, followed by a podium in Qatar.Both riders ended up injured and in the hospital, with Gibernau sustaining a broken collar bone, and both missed the Dutch Grand Prix at Assen.With Gibernau sidelined for the final round of the season at Valencia following a collision with Casey Stoner, Ducati recalled Bayliss, who was recently crowned World Superbike champion.These words turned out to be true, as the GP7 enjoyed a top speed advantage throughout the season, although the other manufacturers (Yamaha, Honda, Kawasaki and Suzuki) closed the gap significantly by the end of the year.Stoner and his Bridgestone-shod Ducati proved to be the top combination in MotoGP and he won the world championship at Motegi, Japan, on September 23, 2007, four races before the end of the season.In the 17th round of the season at the newly resurfaced Sepang International Circuit in Malaysia, Dovizioso took his second pole of the year in wet conditions.
