In 1954 Hideo “Pops” Yoshimura started the company Yoshimura in Japan. Pops was trained as an airplane mechanic during the war and afterward made quite a reputation working on the BSA’s and Triumph’s of service men stationed in Japan. Pops had quite a talent at modifying existing parts to make more power. Although Pops worked on planes, cars, and all manner of other combustion engine powered vehicles, motorcycles were his first love.
