Shinya Nakano took seventh place on his final ride for Kawasaki, ahead of a poor qualifying Kenny Roberts Jr, with Rossi's team-mate Colin Edwards crossing the line one place higher than he had started, in ninth. Carlos Checa, in his final ride for Tech 3 Yamaha, finished tenth with John Hopkins the only Suzuki finisher after Vermeulen fell on 'unlucky' lap 13.
Joining the Australian on the DNF list were Kawasaki's Randy de Puniet, Honda LCR's Casey Stoner - who will ride alongside Capirossi at Ducati next season - plus d'Antin riders Alex Hofmann and Jose Luis Cardoso.
Those retirements helped Garry McCoy and the new Ilmor team to bring its 800cc machine home in fifteenth place, replicating their debut result at Estoril, and claim another world championship point despite again suffering late race technical problems.
From the 2007 season, all teams will field 800cc machines.
