Hello CooperMan,
I' ve got a Harley. At the bike is an original frontscreen fitted. To legalize it I've got a letter from Harley Germany that the screen is
part of the "Allgemeine Betriebserlaubnis". The words "of the bike" are missing. A long time I had a real terrible discussion with the man from the "TÜV" (it' s the MOT) that he wants a special "Allgemeine Betriebserlaubnis" for the screen in cause these words are missing.
You can be sure, he would realize that the mirror is wrong.
