Hi, You always learn something new!
My 5084 and 5128 must be two of these german bikes as they both have this theftcover and the VIN on the right side. (I live in Sweden).
I bought both of them in boxes with lots of missing parts so there were no winkers, exhaust etc left. I restored them both to the American style but as I understand of this discussion they should have some other parts regarding light switch, winkers, neiman-lock and so on. For now I think Iīll keep them as they are
I attach a pic of 5084 steering head.
