MotoGP: 2015 All Races - 720p - MP4 - x265/HEVC - [[OptimusPr1me]]

The 2015 Grand Prix motorcycle racing season was the 67th F.I.M. Road Racing World Championship season. Marc Márquez started the season as the defending riders' champion, having won his second consecutive title in 2014.

Valentino Rossi led the championship for almost the entire season as he chased a tenth world title, but ultimately, the honours went to his Yamaha Motor Racing team-mate Jorge Lorenzo, who took his third MotoGP title and a fifth world title overall. Lorenzo started the season quietly with three finishes off the podium, whereas Rossi took wins in Qatar and Argentina. Thereafter, Lorenzo took four successive wins for the first time in his career to bring himself back into the championship race, before Rossi won at Assen. Lorenzo did not win again until Brno, taking the championship lead on countback, but ceded it back to Rossi, when he won at Silverstone. Lorenzo crashed out at Misano, while Rossi finished fifth – ending a 16-race streak of podium finishes – after both Yamaha riders were caught out by wet weather. In the final five races, Rossi finished ahead of Lorenzo once, as Lorenzo continued to close the points gap; at a maximum of 23 after Misano, Lorenzo pulled it back to 7 going into Valencia. At the final race, Lorenzo took his seventh win of the season, while Rossi could only finish fourth – after a back-of-the-grid start – to give him the title by five points.

Third place in the final riders' championship standings went to Márquez, who won five races during the season, but six retirements during the campaign stopped him from challenging the Yamaha pair in the championship run-in. The only other rider to win a race during the season was Márquez's Repsol Honda team-mate, Dani Pedrosa. Pedrosa missed three races at the start of the season, after electing to undergo surgery to alleviate issues with arm-pump. Upon his return, he did not podium until Catalunya, and ultimately, took two wins in the closing four races at Motegi,and Sepang.
