Jorge Lorenzo has won a fifth world title after taking the MotoGP championship at the final race in Spain.
The Movistar Yamaha rider won both the final race of the season in Valencia and the world title as main rival and team-mate Valentino Rossi finished fourth.
Rossi had been forced to start from the back of the grid after appearing to aim a kick at Repsol Honda's Marc Marquez in the previous race at Sepang in Malaysia.
Lorenzo was on pole position in Valencia and led the race for every one of the 30 laps to win ahead of Marquez and his Honda team-mate Dani Pedrosa.
If Rossi had finished second he would have held on to the points lead he had going into the Valencia race but it proved beyond the nine-times world champion.
The Moto2 race win went to Spaniard Tito Rabat on a Kalex and in Moto3 Portuguese Miguel Oliveira secured his sixth race win of the season.
Ninth place was enough for British rider Danny Kent to take the world title on a Honda.
