Word of Mitch’s motor-building skills spread quickly around the Southern California racetracks and in no time there was a hardcore of Pro Circuit riders in the area. After perfecting the art of cylinder porting and polishing, Mitch and his small but elite team of specialists focused their collective energy on other bike parts and brands. Custom-tuned exhausts were the first to roll out of Mitch’s speed shop, followed by racing silencers.
Today, the brand is one of the most respected in the motocross world and has supplied some of the sports most recognisable names – like Jeremy McGrath and Ricky Carmichael – with race-winning equipment helping them to multiple national motocross titles.
