Dungey is a favourite for Team USA in the MXoN after an incredible rookie 450 Class season.

It’s expected that America’s team for the 2010 Red Bull FIM Motocross of Nations will be announced at next weekend’s Rockstar Energy Unadilla National, round nine of the Lucas Oil AMA Pro Racing Motocross Championships on 14 August.

For 2010, the Red Bull FIM Motocross of Nations returns to U.S. soil at Thunder Valley in Colorado in 25-26 September, with Team USA again entering as the favourites despite their team not being announced as yet.

“We have some exciting plans for this year’s roster for the Motocross of Nations,” said AMA director of racing Joe Bromley.

“The Motocross of Nations represents the pinnacle of international motocross competition, and we’re looking forward to fielding a team of riders that is sharp, prepared and dedicated to keeping the United States on top at this prestigious event.

“Unadilla, one of America’s true classic motocross facilities, is perfectly suited for making this announcement.”

The FIM Motocross of Nations is one of the most high-profile motorsports races in the world. It features teams competing by nationality for a combined score to determine the overall championship-winning team. The event emerged in post-war Europe in 1947 and has run uninterrupted since that time.

The United States is the all-time leader in FIM Motocross of Nations overall victories with 20. Great Britain is second with 16. Team USA took victory over Italy and Belgium in last year’s running of the event in Franciacorta, Italy.

Meanwhile, Team Australia is also believed to be in the closing stages of the selection process, however no official word has come through of when it will be announced at this point.
