Newly crowned world champion Valentino Rossi eased to victory over Dani Pedrosa in the Malaysian MotoGP at Sepang on Sunday.
The Yamaha rider passed pole-sitter Pedrosa on lap 10 and was never troubled from that point onwards, winning by more than four seconds.
Andrea Dovizioso, Pedrosa's team-mate at Repsol Honda next season, was third.
Casey Stoner's sixth place finish was enough to secure him second place in the championship overall.
606: DEBATE
"This track is very good for Yamaha and the type of corner is good for my riding style," he said.
"I made a good start, I wanted to try and attack Dani before but he was very fast exiting from the slow corner, so it was quite difficult.
"The last five laps alone in front were difficult, but I have more experience than Dani with these tyres, so it's quite normal that I'm a bit faster. This weekend we worked very well."
Pedrosa, who switched to Bridgestone tyres mid-season and crashed last time out in Australia, said he was happy with his day's work.
"When I was in front I felt that Valentino was comfortable behind me all the time," he said.
"I knew that he would push when in front, but I was unable to improve my pace. Valentino always gives more in the race than in practice, and we need to learn this and push harder.
"The weekend had started hard, but we kept improving and finally were able to get second. Second place is very good and we are happy with this."
