Stoner, who gave up two-wheels last year at the age of just 27, and still at the peak of his career, was considered by many to have 'jumped too soon'.
Maybe he now feels the same. He is now confirmed to be heading to Japan in coming months to complete four tests for the Honda Racing Corporation at the Motegi circuit.
According to 1987 World Champion Wayne Gardner, the tests may lead Stoner to a MotoGP return.
“If the tests go well and if the lap times are there, and if he’s developing the bike with Honda, I think they’ll probably say ‘why don’t you go and do a race or two?’,” Gardner said.
Gardner, who two decades earlier also headed into V8 racing, said that he thinks Stoner "can come back".
“In most cases for people who retire and then come back, it turns into a disaster – the difference is that Casey is obviously an exceptional talent (and) he’s still relatively young," Gardner said on the 'Keeping Track' podcast.
Gardner conceded he was surprised by the news that Stoner would be testing a MotoGP bike so soon.
Certainly, the buzz of winning in V8s has eluded Stoner; the testing in Japan may be an indication he's looking again for the adrenalin rush of a MotoGP bike.
That's something Gardner knows more than a bit about. “When I drove touring cars, it never replaced the thrill of riding a Grand Prix bike. It’s very hard to find anything in the world to replace (that).”
While there may be more to this story, don't go looking for Stoner gridded up at the 2013 Australian Motorcycle Grand Prix at Phillip Island (20th October).
