    2011 R1200RT Fork Oil

    So it seems there are 2 different size fork tubes in the R1200RT series. 35 mm and 41 mm. I have seen various threads regarding this issue, but I have yet to see one that defines what the fork oil capacity requirement is for each. Does anyone know out there?

    I suspect that the Camheads got the larger tubes. The parts fiche cross-reference does not help, as it shows both sizes used 2005-2014.

    My repair DVD calls for 460ml per leg for the 2011 Camhead, 450ml per leg for my 2006 Hexhead which has 35mm tubes.

    Thanks. My Clymer manual indicates 620ml, but does not make reference to tube size and is relative to both RT and GS series. I pulled 500ml out of the tube and I know I lost some through the fork seal, which seemed to blow out during a local ride. I also checked the BMW microfiche through Max’s site, but it did not give oil amounts.

    Another demonstration as to why the factory manual is better than aftermarket manuals.
