Hey all, first timer here. I've got a 1982 BMW R100 (just the R100, no suffix) that needs new fork seals. My bike shop is trying to order the part but the only part options are listed for the CS, RS, and RT. From my own research, it looks like the two options are 45mm and 43mm. Do any of you know which fork seal the basic R100 uses -- the same as the CS, RS, or RT models?
