Yoshimura is a trailblazing manufacturer of high-quality motorbike sports exhausts, headquartered in Nakatsu, Japan. Founded in 1954 by Hideo "Pops" Yoshimura, a dedicated motorbike enthusiast, the company initially began as a motorbike repair shop before evolving into a world-class producer of premium sports exhausts for passionate riders. With a rich history of success in competitive racing, Yoshimura has become one of the leading names in motorbike sports exhausts, offering an extensive range of products for both road and racing motorcycles.
In 1973, Yoshimura expanded its global presence by establishing its US subsidiary, Yoshimura R&D of America, based in Chino, California. This branch was spearheaded by engineer Gene Romero, who recognized the opportunity to extend Yoshimura's influence in the American market. Over the years, Yoshimura R&D of America has become a key player in the motorbike exhaust industry, supplying top-tier products for competitions like AMA Superbike and AMA Motocross, while also collaborating with leading manufacturers such as Honda, Suzuki, and Yamaha to develop bespoke exhausts.
