Less than a week before the start of the first official MotoGP track action of 2009, at Sepang in Malaysia, Ducati's 2007 world champion Casey Stoner has been seen testing on four wheels - in a racing kart.

With his healing wrist apparently causing him no problems, and surely buoyed by beating Ferrari's F1 drivers during a kart race on ice at the recent Wrooom press ski meeting in Italy, Australia's Hereld Sun reports that Stoner was present in Adelaide for 'a half-day track test under the guidance of one of Australia's most successful kart bosses, Remo Luciani, and showed plenty of pace'.

"Karting wise I'm planning to maybe do some racing in the future to hone my skills on four wheels and see how we go," Stoner revealed.

"I did a handful of laps in a kart when I was about 10 years old but since then I haven't been in a real racing kart, only some four-stroke hire karts which are a long way from the real deal," added Casey, who drove a 125cc Monaco kart.

"I've been really happy with [the kart]. I've tested it once before and for me it is a heck of a lot of fun."
