The 2007 Grand Prix motorcycle racing season is the 59th F.I.M.Road Racing World Championship season. The 2007 season is significant as it introduces a new regulation which specifies that competitors in the MotoGP class can use up to 800 cc motorcycles; between 2002 and 2006, competitors had been allowed to use 990 cc motorcycles. While the 800 cc motorcycles have less power, their ability to brake later and carry more speed through turns has allowed them to break lap records in pre-season testing.
Up to the end of 2006, speculation suggested that Honda would have the advantage, as they could modify their existing engines to 800cc specification easier than other manufactuers. In practice, Honda suffered the most from the stage, with only Dani Pedrosa and Marco Melandri making any impression on the leaders, as Casey Stoner scored a string of wins for Ducati, Suzuki saw Chris Vermeulen's first win and John Hopkins' first podium, and Kawasaki also made progress.
