In 1991, Mitch and a two-man team of relatively unknown southern California motocross racers (including a kid named Jeremy McGrath) contested the AMA's supercross series under the Peak Antifreeze, ProCircuit and Honda banners. Six months later, that team swept the 125 East and West supercross championships! Although sponsors and rider line-ups on our record-setting motocross team change from year to year, one thing always stays the same: the Pro Circuit reputation for professionalism and winning. In 1997, another pro motocross rookie-this one named Ricky Carmichael-flew Pro Circuit colors to the 125 national motocross championship that Mitch had dreamed about winning for so many years.
