This is a 91 or 92. Period. Full stop or whatever it is you people say over yonder.
1990 had BATnnn numbers, a few had ATnnn (I've heard about some but never saw one and wondering if the people missed a letter). The 1991 & 1992 models had #'s Axxx and A7F7 is of that format. I don't know if it's a low number or not, I know of bikes that were A3xx is A3 high or low? Who knows. No one can say for sure if it's a 91 or 92 but if Axxx format, it is not a left over 1990.
There were some 1991 models sold with the box crown fork. All of these were sold in Europe except for one that I am aware of. Almost all 91's came with the Uniklein. (I don't know why most went to Europe).
All of what is written above is fact, it's just the way it is and really can't be argued.
Pinguwin isn't mad, I just pity fools.
Thanks. I have already modified my original post to reflect that it is a 1991-1992 bike. I have also changed the information on my online auction. I appreciate your information.
