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.[1] 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.[2]
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.[3][4] 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.[5] 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.[6]
