Yoshimura Japan is a leading motorbike sports exhaust manufacturer based in Nakatsu, Japan. Founded in 1954 by Hideo "Pops" Yoshimura, a motorbike enthusiast, the company started out as a motorbike repair shop and later evolved into a company that manufactures high quality sports exhausts for motorbike enthusiasts.
Since then, Yoshimura Japan has established itself as one of Japan's leading motorbike sports exhaust companies, and has a long tradition of sporting success.
Today, Yoshimura Japan offers a wide range of products for road and racing motorbikes, including exhausts, headers, air filters and other exhaust components. The company has distinguished itself through the quality of its products, which have been successfully used in many high-level competitions in Japan, including the Japan Superbike Championship and the All Japan Road Race Championship. In addition, many Japanese professional riders have chosen to use Yoshimura Japan's products because of their competitiveness and reliability.
Yoshimura Japan uses only high-quality materials and state-of-the-art technology to ensure that its products are durable, reliable, and able to improve motorbike performance.
In 1973, Yoshimura R&D of America was founded as a subsidiary of the Japanese company Yoshimura Japan and is based in Chino, California.
The history of Yoshimura R&D of America began with an engineer named Gene Romero, who worked as a test rider for the Japanese company and saw an opportunity to expand Yoshimura's presence in the United States. With the help of Yoshimura Japan's founder, Gene opened a subsidiary in the US to produce and sell sports exhausts for American motorbikes.
Over the years, Yoshimura R&D of America has established itself as a leading manufacturer of motorbike sports exhausts in the US, becoming the leading supplier of exhausts for AMA Superbike and AMA Motocross competition. The company also began working with some of the leading American motorbike manufacturers, such as Honda, Suzuki and Yamaha, to develop custom exhausts for their models.
In addition to its racing successes, Yoshimura R&D of America has distinguished itself through the quality and durability of its products, which have been used successfully by motorcyclists of all levels, from beginners to professionals.
