1957 YD-1

Collection items

(1957 / Production Model)


This is a model born out of a pursuit of design originality. Taking “a 250cc for the Japanese” as its key words, it was given a compact and easy-to-ride body size that fit the Japanese physique. It also embodied a “dynamic design” that gave the impression of powerful dynamism in any situation. It mounted Yamaha Motor's first 2-cylinder engine. In the world of Japanese motorcycles that was dominated at the time by utility models, the YD-1 brought a new style of sports motorcycling to the market.
