Those hoping that Stoner will follow in the recent footsteps of F1 world champions Michael Schumacher and Kimi Raikkonen by returning to action a few years down the line are also likely to be disappointed.
“This sport would have to take dramatic changes for me to even consider coming back. I can never say never, but honestly I have no thoughts at this time of ever coming back,” he said.
The Valencia Grand Prix will be held from November 9-11, when Stoner will be chasing a 39th and last MotoGP win. A Valencia victory would also match new double champion Lorenzo and runner-up Pedrosa for six wins this year.
Two days later the likes of Lorenzo and Pedrosa will be back on track testing their 2013 bikes, while Stoner - who made his MotoGP debut in 2006 - will be starting retirement.
