The successor of the YA1, the (you guessed it already!) YA2, appeared in November 1957. Its construction had not much to do with the YA1 anymore. It was a quick transformation from a DKW replica to a Yamaha original. Teh design with a pressed steel frame was easier and cheaper to produce than the old tubular design of the YA1. It also had a bootm link front suspension and a normal rear swinging arm. It was a slim motorcycle with a weight 0f 103.5 kg. Length was 1870 mm with a wheelbase of 1245 mm. The 123 cc engine developed 6.8 hp. The colour was reddish metallic silver with chrome tank panels. It was also the first Yamaha with an electric starter, The second picture from the top left shows the YA3, introduced in December 1959. Colour was now black and the toolboxes were protruding from the frame now. Yamaha received a Government Good Design Award for this motorcycle, which was also Yamaha's first volume model.
