AM Open of Supercross and AZ Open of Motocross—one legacy, two starting gates
AUGUST 2, 2026 · ARIZONA CYCLE PARK

TWO STARTING GATES.
ONE ARIZONA LEGACY.

The AZ Open of Motocross has spent more than 25 years building a championship tradition at Arizona Cycle Park. In 2026, that experience also launches a new chapter: the AM Open of Supercross.

Race two purpose-built Supercross weekends in October, then return in December for the three-moto AZ Open championship and your chance to earn the cactus. Two disciplines. One home in Buckeye, Arizona.
