Yamaha were a musical instrument manufacturer that had been founded in 1887 but diversified into motor cycle manufacture in 1955. Their first machine, the YA1 was a 125cc two-stroke based closely on the pre-war DKW RT125. It was soon followed by 175 and 250cc models. It was soon followed by 175 and 250cc models. By 1960, Yamaha were exporting to the US and developing specialized racing bikes. By the end of the 1960s, five World Championships had been won by riders using Yamaha machines. This guide celebrates six classic Yamaha models.
