This was Yamaha Motor's first motorcycle. At a time when motorcycle design was dominated by imposing all-black styling, the YA-1’s simple form and chestnut red coloring quickly made it popularly known as “the Red Dragonfly.” 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 later that year. In an era when the average starting salary of a college graduate was around 10,000 yen, the YA-1’s 138,000 yen price put it well beyond the reach of most users, but in three years, 11,000 YA-1s were sold.
After a 1-year hiatus from factory participation, this new machine was introduced at the opening round of the 1977 season. The engine featured a new bore x stroke spec (54x54 mm changed to 56x50.6 mm). Furthermore, the cylinder pitch was increased (92→115 mm) to allow greater freedom in scavenging port design. The piston valve was changed to a suction type and a power-jet type carburetor adopted to achieve higher revving and increased power output. The aerodynamics of the chassis, including the rider, was re-designed for increased performance. That year Steve Baker mounted the podium in six rounds to end the season ranked 2nd.
