BMW didn't officially export bikes to the US until 1955. There are English language owners manuals for many of the prewar models (because they were exported to Britain), but the parts books are all in German. And most experience with these bikes, and reproduction parts, still resides in Germany.
My current MC projects are Spanish, German & Japanese. I have never found a need to speak 2 of those 3 languages.
