Due to an overwhelmingly positive response, the Tour has added the Pro SuperSport "UTV" class to its Pro lineup, which also includes the popular SuperQuad Pro 450 MX and the Pro Stock QuadTerrain Challenge classes.

"When we ran the side-by-side vehicles at our last race of 2006, the excitement from our fans, our teams and our stakeholders was unmistakable, making it an obvious addition to our already thrilling Pro ATV racing show," said PowerSports Entertainment, Inc. CEO Rick Murphy. "This, along with some important changes in our Pro-Am, Amateur and Youth classes, should make 2007 one of our most exciting seasons on record."

In addition to the changes in the Pro classes, the Tour will provide alternative lines for riders wishing to run in the Amateur QuadTerrain Challenge classes, which includes Stock Lites (601-700cc), Stock Unlimited (601+cc), and Modified.

"We are dedicated to our ladder system in the PowerSports ATV Tour," said Scott O'Malley, president of PowerSports Entertainment, Inc. "It's important we allow Amateur riders, who have limited budgets and experience, a place to compete with an eye on stepping up to our top QuadTerrain Challenge Class. Alternative, amateur, lines will give these riders a place to compete without the concern of damaging equipment or racing at a level beyond their experience."

YOUTH CLASSES
