One-time desert racing pro and motor tuning specialist Mitch Payton, founded Pro Circuit in 1978 at the age of 18. 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 riders was formed. Custom-tuned exhaust pipes were the first Pro Circuit high-performance accessory to roll out and they quickly expanded their product line to include suspension, exhaust systems and motor accessories for different bike brands.
Products like their Works pipe, R-304 silencer, Ti6, engine components, triple clamp sets, clutch covers and more were all painstakingly put together in an effort to ensure customers have the very best to put onto their motorcycle. These products have taken wins in supercross, outdoor nationals, along with amateur and off-road events throughout the years. For close to 45 years, they have been committed to designing and manufacturing the finest performance parts on the market for dirt bike and ATV riders.
