Back at the sharp end it was Corser from Haga with youngster Max Neukirchner giving chase and Bayliss slotting into fourth place. Neukirchner tried for second place but Haga wasn't having it and the determined Japanese rider soon took the lead from his team-mate.
Biaggi who also got tangled up in the turn one crash had rejoined the action in 13th whilst Toseland was running 17th. Biaggi ran wide in his efforts to get further up the standings and when he came back onto the racing line he was very lucky not to get taken out by Karl Muggeridge.
On lap four Neukirchner set a new lap record of 1min 39.844secs while Michel Fabrizio was hit with a ride through penalty for a jump start. By lap five Biaggi was tenth and Toseland eleventh. Haga had a bit of a moment but managed to hold it. Just three laps later and both Biaggi and Toseland were into the top ten.
Neukirchner was all over the back of Corser and was lining him up to try and take second place. He put a hard move on the tough Aussie forcing him to sit up mid corner. Corser wasn't letting him away with it and took his position back, while these two were dicing Bayliss was gradually closing down on them.
Ruben Xaus got caught up in the Biaggi –Toseland freight train as the pair of them sandwiched him through a corner pushing him back two places. By now Bayliss was getting impatient and shoved his way under Neukirchner physically bumping the German rider out of the way.
Bayliss now had Corser in his sights and it all kicked off on lap 19. the feuding Australians changed place four times, bashing elbows all the way, but it was Bayliss who came out on top.
Toseland came over the line in seventh place and now has 405 points, 17 clear of Haga who is second. Race two will decide the Championship.
