COMPANY HISTORY
One time desert-racing pro and motor-tuning specialist Mitch Payton founded Pro Circuit in 1978 at the age of 18. Early Pro Circuit pipe customers were mostly Husqvarna-mounted desert racers and motocrossers who wanted Mitch to provide the same speed set-ups that he and his father had learned to dial in on Mitch's personal race machines. Word regarding the success of Mitch's motor-building skills traveled quickly around southern California racetracks and in no time the cult of Pro Circuit motorcycle exhaust riders was formed. Mitch closed his family's Husqvarna dealership in 1980 to focus his energy on the shop's aftermarket hop-hop service business full-time.

After perfecting his skills in the black arts of cylinder porting and polishing, Mitch and his small-but-elite team of speed specialists focused their collective energy on other bike parts and other brands. Custom-tuned exhaust pipes were the first Pro Circuit exhaust system high-performance accessory to roll out of Mitch's cluttered speed shop, followed by racing silencers. Pro Circuit pipe business was brisk, and pretty soon every PC-equipped racer was requesting PC performance modifications for other parts of their bike. Pro Circuit obliged by opening a suspension shop and expanding the available line of Pro Circuit motorcycle exhaust systems and motor accessories for different bike brands. With so many Honda-, Kawasaki-, Yamaha- and Suzuki-mounted racers across the nation running Pro Circuit equipment, it didn't take long for the PC brand to start racking up championships. Pro Circuit's phenomenal racing success rekindled Mitch's competitive fires, so in early 1990 he set Pro Circuit's sights on the holy grail in off-road racing: winning a national motocross championship. But doing so would mean challenging the Big Four at their own game and would require a serious financing. To make this goal a reality, Mitch borrowed a strategy from the auto-racing game-securing a corporate sponsor. By doing this, Mitch changed the way motocross teams would be financed and packaged forever.
