... during an official test day for the next round at Queensland Raceway in two weeks.
Crusty Demon Matt Schubring from nearby Boonah helped promote the Ipswich event with a spectacular somersault jump over the Kiwi race driver and his Stone Brothers Racing team truck.
Van Gisbergen, who is third in the championship, watched the stunt from the top of the truck and commented: "That's pretty cool.''
The quietly spoken driver owns a similar KTM bike, but says he rarely uses it despite many V8 Supercar drivers, such as Russell Ingall and Craig Lowndes, augmenting their training with motocross and trail riding.
"I'm too young for that,'' the 22-year-old joked, referring to veteran drivers Lowndes and Ingall. "I'd rather go around the track, anyway.''
Surprisingly, 29-year-old Schubring says he's getting too old for the extreme sport.
"The peak for this sport is about 22,'' he says.
However, yesterday's stunt was a breeze for the extreme games expert who practices similar jumps almost daily on his property.
While the famous American Crusty Demon stunt bike team is taking a year off touring, Schubring is busying himself opening the Wyaralong trail riding facility near his home town.
He is also coaching riders in Perth, travelling Australia to shot a video of his stunts and will show his skills at the Ipswich V8 round from August 19-21 and at the Brisbane Exhibition.
