I had a Yamaha RD 250, which I bought new on plate GUV 62J and I loved it, for four years till kids made it impractical and the old man got difficult. Looking up that year, it´s 1970, this site as RD250´s listed from 73. I know it was one of the first in the country. What´s wrong? my memory? was it an import, or are there bits missing from the Yamaha listing?
