1970 Inter-AM Motocross Series
The 1970 Inter-AM motocross series was the 4th edition of the international racing series established by the American distributor for Husqvarna Motorcycles Edison Dye, as a pilot event to help establish motocross in the United States. The motocross series was an invitational based on a combined 250 and 500cc engine displacement formula, run on American tracks featuring some of the top competitors from the Motocross World Championships racing against the top American riders.
Maico factory team rider Åke Jonsson won the series with seven victories to finish ahead of Husqvarna teammates Bengt Åberg and Christer Hammargren in second and third places. Åberg was filmed while competing in the final round of the series at Saddleback Park as part of the 1971 Bruce Brown motorcycle documentary film, On Any Sunday. The film's success was credited with helping to spark an explosive growth in American motorcycle sales numbers as the baby boomer generation came of age.
