    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?

    I have a base '81 R100 as well and I've always wondered the same thing when trying to order parts! The base R100 is never listed and I never know which of the others is the closest! Waiting with you to find out

    I guess that's comforting to know that it's not a unique problem. I'll be sure to post if I find the answer outside the forum.

    what should matter is the year, not the model. the rs and rt are just the basic bike with fairings.

    I think you need a different shop.
