WHITE BEAR LAKE, Minn. (Dec. 28, 2006) — The WPSA PowerSports ATV Tour
will sanction 27 Pro, Pro Am, Youth and Amateur classes during the
2007 ATV racing season. 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.”

The Tour has made several notable changes to its youth classes.
Production Lites 13-15 will remain the same as in years past, while
the 0-50cc Junior and Senior Classes have been modified. The 0-50cc
Limited Class (4-6) will be open to quads with automatic clutch, and
CVT belt drives, while the 0-55cc Production Class (6-8) will be open
to quads with auto clutches.

The balance of the youth classes are: 51-70cc (production, auto clutch
6-11); 70cc (shifter, 6-11); 71-90cc, 2 Stroke, 75-125cc, 4 Stroke
Production (8-11); 71-90cc, 2 Stroke, 75-125cc, 4 Stroke Production
(12-15); 90cc Production (CVT belt drive, 8-15); 75-125cc 4 Stroke
Production (8-15); 90cc 2 Stroke, 125cc 4 Stroke Modified (8-12); and
105cc 2 Stroke, 150cc 4 Stroke SuperMini (12-15).

The Tour has also split the women’s class into two classes: A and B/C.

The 2007 Rulebook, which is in the final stages of completion, will be
distributed soon via www.PowerSportsTour.com.
