Yamaha was established in 1887 as a piano and reed organ manufacturer. After World War IIthe YA-1 (AKA Akatombo, the "Red Dragonfly"), of which 125 were built in the first year of production (1954), was named in honor of the founder. It was a 125cc, single cylinder, two-stroke, street bike. The 125cc won the 3rd Mount Fuji Ascent Race in its class and also sweeping the podium with first, second and third place in the All Japan Autobike Endurance Road Race that same year.
