Opferman, can you give me any idea as to the changes from one "modern" Maico to the next?
Visually they seem to have had a few clear changes from the first in 85, then again in the early 87, then not really till about 92 then again in 94. After that they seemed to be updated visually for the last time, with the 97 looking very similar to the bike Kostler still sells, obviously USD's were added in 2001 and no doubt a lot of other minor mechanical details.
Though the blue 94-96 Maico's seem rare (I am lucky enough to have one), I think the blue bikes from 87 to 93 in seem to be the hardest to come by. I am yet to see anyone who owns one, (online or otherwise) and have never seen one for sale.
86's although by no means common seem to be around a little more.
