Hayden finished one place - but a massive 14-seconds - behind his team-mate, while Capirossi, Nakano, Elias and Bayliss completed the top ten.
Bayliss was the only Camel Honda to finish after Alex Barros fell heavily from eighth on lap 13; the unlucky Portuguese Grand Prix winner's body language suggesting some form of injury as he lay next to his prone RCV.
Meanwhile, the dry weather prevented home hero Olivier Jacque from the chance to repeat his Shanghai heroics, but OJ did bring his ZX-RR home in eleventh place on what is expected to be his final Kawasaki ride.
Rossi now leads the 2005 MotoGP World Championship by an increased margin of 37-points over Melandri heading to his home grand prix at Mugello, while Gibernau's second place means he has now advanced to third in the standings – just 5-points behind his young team-mate.
