The first-ever motocross stadium event took place July 8, 1972 at the Los Angeles Memorial Coliseum in front of a crowd of 29,290.
Many people thought the idea to build a man-made course and tear it down within a week was unreasonable, but the event was a resounding success, and eventually went on to become the largest motocross event series in the United States. California locals had the privilege of watching both European and American racers compete in their backyard, with some of the best contestants as young as sixteen!
It has been said that the 1972 Superbowl of Motocross event set the stage for the most popular form of motorcycle racing, and will be remembered as the night that motocross became a household word.
