Repsol Honda rider Dani Pedrosa has won at Valencia today in tricky conditions which saw riders roll up to the grid on a mix of wet and slick tyres.
With the track drying Pedrosa, Cal Crutchlow, Nicky Hayden and Alvaro Bautista opted to change from wets to slicks and start the race from pit lane.
2012 champion Jorge Lorenzo was the only front runner to start the race on slick tyres, struggling to get away from the line.
Aprilia CRT rider Aleix Espargaro was the surprise leader over the first few laps on wet tyres, but he soon dropped a couple of places before changing to slick tyres.
Lorenzo's gamble paid off as his tyres came up to temperature and the Spaniard soon took to the front. Pedrosa and Crutchlow quickly worked their way through the field, with Pedrosa quickly catching Lorenzo by the half way stage.
With 16 laps to go, Lorenzo caught up to several back markers. He tried to pass James Ellison round the outside and in the process ran on to the wet tarmac, being thrown off the high side of the bike.
This pushed Pedrosa in to the lead ahead of Yamaha test rider Katsuyuki Nakasuga and Crutchlow.
Crutchlow then passed Nakasuga to take second position, but crashed on the brakes going in to the final corner with just seven laps remaining.
At 31-years-old Nakasuga managed to finish in second place.
After switching to slick tyres early in the race, Casey Stoner was starting to move up the order, and with just a couple of laps remaining passed Alvaro Bautista and moved in to third place to finish his final MotoGP race on the podium, one minute behind Pedrosa.
San Carlo rider Michele Pirro was the first CRT rider home in fifth place behind Bautista.
Espargaro finished 11th behind Valentino Rossi to secure the inaugral CRT championshipp.
