YA-1(1955 / Production Model)
This was Yamaha Motor's first motorcycle. At a time when motorcycle design was dominated by imposing all-black styling, the YA-1 with its simple form and modern chestnut red coloring, quickly became popularly known by the nickname “Aka-tombo” (the Red Dragonfly). What's more, it immediately demonstrated its high performance by winning the 3rd Mt. Fuji Ascent Race in July 1955, and then swept the top three places in the ultra-light class of the 1st Asama Highlands Race (All Japan Motorcycle Endurance Race) in November of that same year. In an era when the national average starting salary of a male college graduate was 10,780 yen, this model, priced at 138,000 yen, was a coveted extravagance beyond the reach of most users. Regardless, in three years, 11,000 YA-1s were sold.
