Well it 'ain't over until it's over in my book....
but 'supposedly' Rossi's comments that it is only the bike and not the rider is a little far fetched. If it is only Stoner's bike that is winning, why is Capirossi doing so badly...

In reality, Yamaha were so full of themselves that they thought they could cobble any piece of rubish together and they would win....Presumably Rossi had his imput into this crap bike as well!
Rossi concedes MotoGP title to Stoner
Tuesday September 4, 2007
AP - Valentino Rossi believes he has no chance of catching Australia's MotoGP leader Casey Stoner after being forced to retire during the San Marino Grand Prix.
Rossi's Yamaha broke down on lap five on Sunday at the Misano circuit while he was in fourth position.
Stoner won the race on his Ducati for his eighth victory of the season to extend his lead over Rossi to 85 points with five races to go.
"I really needed a podium finish," Rossi was quoted as saying by Gazzetta dello Sport on Monday.
"By now, the world championship is over."
Chris Vermeulen of Australia was second and John Hopkins took third on their Suzukis.
Rossi, who has been hampered by engine and tyre performances this season, said Stoner deserved to be champion - but that the role of the rider in winning races was diminishing in importance.
"That Stoner and Ducati deserve the title is certain," Rossi told Gazzetta.
"But our sport has changed. We are getting closer to Formula One. There is no longer space for the rider who makes the difference."
Stoner leads the overall standings with 271 points after 13 races.
Rossi is second with 186 points, followed by Dani Pedrosa of Spain with 168.
Despite a seemingly insurmountable lead, Stoner is concentrating on the Portuguese GP in two weeks.
"My tactic hasn't changed," Stoner told Gazzetta. "I continue to take it race by race."
