Two-time MotoGP World Champion Casey Stoner says he is “not interested” in returning to the top-tier of motorcycle racing as he continues to come to grips with a brand-new career in V8 Supercars.

The Australian shocked the sport when he stepped away at the peak of his form, citing frustration with the nature and politics of the paddock as his primary reason.

Stoner was only out of the spotlight for a brief moment, confirming widespread speculation that he would pursue a drive in the V8 Supercars’ development ranks – the Dunlop Series – with Triple Eight Race Engineering.

He said while he misses the thrill of two wheels, he did not regret the decision to move on from MotoGP.

“I miss riding bikes, but that’s the only aspect of it,” Stoner said. “A lot of the reasons that I left are definitely deep enough in there that I’m not getting cold feet and wanting to get back on a bike.

“I’m definitely happy with the decision I’ve made, and to be honest I’m not interested in going back.”

Stoner made his V8 Supercar debut on one of the world’s toughest street circuits in Adelaide in March, impressing many with his performance in his first-ever car race.

A deflating tyre saw him glance a concrete wall in his first outing, resulting in a DNF, though he managed to hold his own in mid-pack for a 14th place finish in his second race.

He will line up for the second round of the Dunlop Series at Perth’s Barbagallo Raceway this weekend, eager to continue scaling a steep learning curve.

A relaxed Stoner said he was enjoying the new direction, and felt like he now had time to enjoy his passion for motorcycles.

“Bikes are where my passion will always be. I love riding them,” said the 27-year-old.

“Now I actually get to enjoy riding them a lot more because before we didn’t have any time to enjoy it and smell the roses. It was all focused and serious the whole time.”

Prior to his departure from MotoGP, Stoner was a strong critic of a raft of technical changes within the category, and also questioned the nature of the sport following the tragic death of Marco Simoncelli in 2011.
