Starting back in 1954, the success of yoshimura as one of the world’s largest performance aftermarket sportbike exhaust companies didn’t happen overnight. founded by hideo yoshimura, or “pops”, as he was known by, he started out with a few dedicated employees working in a small race shop. the shop was quick at pumping out fast race car and bike motors, the reputation of “yoshimura-built” motors grew and he soon created a cult-like following among racing enthusiasts. with this momentum pops turned his attention to the u.s.
