TOOELE — Two-wheeled enthusiasts will have the best of two worlds this weekend at Miller Motorsports Park, as both motorcycle road racing and Supermoto competition are on tap. This weekend is the fourth round of the seven-race Honda Presents the Plaza Cycle Masters of the Mountains series.

The series, developed by Miller Motorsports Park, organized by the Utah Sportbike Association (USBA) and sanctioned by the American Motorcyclist Association (AMA), was created to encourage and develop fun and competitive road racing at the club and regional levels.

Riders will be competing on the West Course on Saturday and Sunday in 18 different classes for contingency money (provided by sponsors for using their products in some classes), trophies and points toward the series' class championship.

Also competing will be the western region of the U.S. Grand Prix Racers Union (USGPRU), the officially recognized 125cc and 250cc Grand Prix National Championships. Tickets are priced at $5 per day. Kids 12 and under will be admitted free of charge.

The Miller Kart Track's auxiliary paddock track will be open for concession rentals on Saturday, with the main circuit available on Sunday. Also, the Miller Motorsports Park Club House will be open to the public all weekend and will serve Sunday brunch from 10:30 am - 2:30 pm.
