Can someone tell me what this part number suits?

12200-00B22 it's a crank for an RM250 of some description the model eludes me as obviously it isn't from pre'78

(Gloat time) I just won all the items in below pics for $60au shipped to my door so now I just have to look around for a bike to fit them on..err..if I knew what model I'm looking for that is been thinking of buying a late model so this maybe just the incentive I need. thanks

The crank is probably from the 86-88 RM250.

If it helps, 12200-00B20  was added to our computer list at work in October 1997

thanks guys. The number added to your list in '97 is infact the number for the years CG mentioned. I guess somewhere around this era also after looking through some parts lists. Still any '86-'88 model RM is still quite a late thing in my eyes better get looking before the pre90 guys clean it all out and push the prices through the roof
