At the first corner Alex De Angelis and Spaniard Dani Pedrosa crashed out and both were unable to restart. Chris Vermeulen also ran off track at the first corner. Dissolving any hopes he had of a good home race.
Briton James Toseland got an excellent start to make his way up to third place ahead of fellow rookies Andrea Dovizioso and Jorge Lorenzo.

It took several laps and several overtaking attempts for Rossi to get past Toseland and pull away in pursuit of the leaders.
Rossi managed to close the gap on second place Hayden and on the penultimate lap made up over half a second on the American. On the penultimate lap Rossi passed Hayden. Hayden tried to respond but made a mistake which saw Rossi slightly pull away.

At the beginning of the final lap Lorenzo was in fourth place while Nakano was in seventh. But when the group crossed the line Nakano was fifth, pushing Toseland back to sixth and Dovizioso back to seventh. This meant Toseland equalled his best race finishof sixth.
