Nazi Motorcycles

Who knows their motorcycles? I noticed this on the street in Gythion. My first thought knowing how proud the Greeks are of their resistance to the German invasion and occupation is that this is a war trophy. I have seen this before in towns on Crete, BMW motorcycles proudly displayed in front of shops as a monument to their expulsion of the Nazi occupiers. But that was decades ago and I don't remember the details of the models used by Germany during World War II.
