Recap: MotoGP 2015 celebration to controversy, Lorenzo crowned World Champion in a great season of racing

It wasn't always easy, but the best things in life never are. It's official, your MotoGP 2015 World Champion is Jorge Lorenzo. In a celebration of the greatest season of racing in the premier class in recent years, Lorenzo wins an incredible race to lift his fifth world title with Marquez and Pedrosa on the podium and Rossi fourth after an amazing ride.

Here's everything you need to know.

Movistar Yamaha’s Jorge Lorenzo led from flag to flag to become the 2015 MotoGP™ World Champion in one of the most dramatic races of the year in Valenciana. In the process Lorenzo became only the third rider in the premier class to overturn a points deficit in the last round to become champion and the first since Giacomo Agostini in 1966 to win the final race of the season to clinch the title.

His Yamaha teammate and title rival Valentino Rossi, who started from 25th on the grid after Cal Crutchlow was forced to start from the back of the grid, rode one of the races of his life to cross the line in fourth, but despite his best efforts, the ‘Doctor’ could do nothing to stop Lorenzo becoming champion in the end. Lorenzo eventually took the race win by just 0.263s from Repsol Honda’s Marc Marquez, with his teammate Dani Pedrosa in third after thrilling finish that could have seen a very different outcome to the title battle.

#TheGrandFinale certainly lived up to the hype as 110,000 fans at a sold out Comunitat Valenciana – Ricardo Tormo circuit bore witness to one of the most tense and thrilling conclusions to a MotoGP™ season ever. Read more on MotoGP.com
