My dealer has a nice F800R for sale. Only problem, being vertically challenged (28" inseam), I would have to lower the seat height a fair bit . I've seen a lot of posts about lowering the GS models and was wondering if anyone has any experience/info if that can be done to the R and if so what would be the lowest seat height I could expect if I did all the lowering I could do with this model; suspension, factory kit, seat, the whole ball of wax?
