Newly-crowned world MotoGP champion Valentino Rossi has admitted his surprise at winning the title in his first year with new team Yamaha.
Rossi, who switched from Honda this year, clinched his fourth successive title at Phillip Island, Australia.
Rossi said: "When we tested the bike the first time, it was a good feeling but it needed more time.
"The team has worked very well. I think this is the best year for me, the way I have ridden and everything."
Rossi only needed to finish second in Australia but put in a daring passing move on rival Sete Gibernau on the last lap to take the chequered flag.
The Italian gave Yamaha their first world crown since 1992 and became only the second rider to win consecutive titles with different manufacturers.
With one race remaining, Valencia's Spanish MotoGP on 31 October, Rossi has 279 points to Gibernau's 244.
"It was a great battle with Gibernau. Today I was very fast. I waited and stayed behind Gibernau, but with less fuel the bike started to feel good.
"In the last lap it was incredible, a lot of fun for everyone. It was unbelievable for me to win the race."
