Does anyone know if the later BMW fairings will fit on the earlier R bikes. I have a 1975 R90/6 and would like to find a fairing that is more aerodynamic (Not a bikini S fairing) but offers the protection of the some of the later BMW fairings. I am looking for a complete fairing with leggings. Currently I have a Windjammer III but it is not aerodynamic at all...but offers very good protection. Thanks for the advice.
