2012 Grand Prix motorcycle racing season
The 2012 Grand Prix motorcycle racing season was the 64th F.I.M. Road Racing World Championship season. Casey Stoner started the season as the defending World Champion, while Honda was the defending Manufacturers' Champion. Moto2 champion Stefan Bradl joined the MotoGP grid with LCR Honda and 125cc champion Nicolás Terol entered Moto2, racing for Aspar.
In the premier MotoGP class, the championship battle revolved around Yamaha rider Jorge Lorenzo and Honda pairing Dani Pedrosa and defending champion Stoner. Lorenzo won four of the first six races to be held in the campaign to open up an advantage over Stoner, before he was taken out of the Dutch TT on the first lap by Álvaro Bautista; Stoner won the race to eradicate the points lead. In the next race, Stoner crashed out of the German Grand Prix on the final lap and allowed Pedrosa to take his first win of the season. Stoner struggled in the next few races – despite a victory at the United States Grand Prix – with his championship challenge ended by a qualifying crash at Indianapolis. After ankle surgery, he returned to the series and won his final race of his career at his home race, the Australian Grand Prix, for the sixth successive season. Pedrosa went on a run of five victories in six races, with the streak being interrupted by a first-lap crash at Misano, where he was taken out by Héctor Barberá. Lorenzo finished second to Pedrosa on each occasion that he had won, and he took advantage of Pedrosa's accident to win at Misano. Lorenzo ultimately won the title with a second-place finish to Stoner in Australia, after Pedrosa had crashed out of the lead early on.
In the other classes, Marc Márquez won the Moto2 championship title after a season-long battle with fellow Spanish rider Pol Espargaró; a third-place finish for Márquez at the Australian Grand Prix – despite a win for Espargaró – was enough to give him his second world title before moving into the premier class for the season. He took his last victory in the class at the Valencian Grand Prix, the last event of the season, despite starting from 33rd on the grid. This performance, which included overtaking 20 bikes on the first lap alone, meant the biggest comeback in the sport's history. Márquez's result was enough to give Suter the constructors' title for the class. The inaugural Moto3 world championship title went to German rider Sandro Cortese, following his fourth victory of the season at the Malaysian Grand Prix, which gave him an unassailable points lead over his two title rivals Luis Salom and Maverick Viñales in the championship race. Cortese also became the first rider to win any Grand Prix title for the Austrian manufacturer KTM. KTM also won the constructors' championship at the Australian Grand Prix, doing so after Cortese won the race.
