Ok, that makes sense ...
Some models just don't make it over to here. There may have been an RD125 in the states but I don't believe so. I know there was never an RX model (in the states) from at least 1973 and up, all RD's..
Your bike appears to be pretty much a half of an RD 250 in excellent condition. I miss my old 1975 RD350, (an old man turned left in front of me in 1977, totaled it and almost took me out indefinitly when I was 19)
It's seemingly in pretty good condition, just a couple of quibbles really. Heck, it's probably in better condition than the similar 80 I had 20 years ago.
Yikes on the crash, lucky it didn't end up worse.
Anyway, hopefully get the wheel back so I can put her thru her paces on the weekend... and sort out any (hopefully) minor issues
