You may not have heard his name or run one of his pipe’s before, but you have undoubtedly felt Bill’s influence on the world of dirt track racing and motocross. Throughout the 2 stroke race bike’s formative years, Bill Cervera was on the razor’s edge of header and exhaust design, working alongside factory teams and eventually launching his own team. He’s left an indelible mark on the sport over a continuing career in performance motorcycle exhausts spanning more than 4 decades, and may have more exhaust experience - 2 stroke or 4 stroke - than anyone else in the biz. Today, Bill’s Pipes are still pouring on big power for off road bikes, available for both 2 and 4 stroke machines and optimized for everything from wrist-wrenching enduros to keyed-up, wrung-out MX.
