Sometimes there are problems with spelling and/or sound, resulting in the opposite..or otherwise wrong meaning than what was meant. The German "Auf" is such a situation. We usually order by part number or perhaps from a sketch or we describe where it goes/fits/etc. Almost all the time, this works quite well. Not always. There are a few instances where languages have caused some serious confusion (besides politics and personal relationships!). There are situations where something is not described in your language properly, only in German, in literature pertaining to our motorcycles.
