Press launches/review seem to have it at 11600 and it's now 11900 on bmw UK's site? So it's gone up 300 which inflation/brexit easily accounts for in the 2yrs. You sure you aren't confusing it with the scrambler which is ~1.5k less? It is quite funny that it's so much more than the R1200R which looks pretty much identical... but I guess demand must be high.
Anyways such bikes are really pretty, but I can't afford to have loads of bikes at home so one will have to do ehehe. I do like the R1200RS a lot, it was too much though compared to the K1300R.
