Engine displacement
Engine displacement was reduced to 800 cc for the season. Ducati started development of its 800 cc motorcycle extremely early, and according to Ducati's racing chief Filippo Preziosi, by August 2006, Ducati had already built twenty 800 cc engines with various specifications. Loris Capirossi was joined in the team by Casey Stoner. During the most part of the 2007 season, Stoner dominated the field, obtaining his and the team's first MotoGP World Championship at Twin Ring Motegi on September 23, 2007, four races before the end of the season.
