The Petronas FP1 is a 899.5 cc (54.89 cu in) liquid cooled inline three-cylinder homologation special sport bike that was produced in 2003 by Petronas. Originally developed jointly by Petronas and Sauber Petronas Engineering as the Petronas GP1 989cc prototype to compete in MotoGP, Petronas decided to race the motorcycle in the Superbike World Championship instead. To meet the requirements for the motorcycle's entry into the championship, the engine was reduced to 899.5 cc (54.89 cu in) and Petronas had to produce 150 road version motorcycles for FIM homologation.
