Dont kidd yourself...I would not waste my time on a 1200...The 1250 might not be a big upgrade on paper but in real life the difference is like weak coffee compared to a rich mocca latte... the additional 84 cc and 2 intake cam-lobes make a huge difference ! ESpecially when you make a side by side roll-on against the weak 2017-18 EU-4 R1200GS !
Sorry but unless you are riding like an utter and complete TW*T on public roads there is very little difference in performance between the later 1200 models and the 1250 .
Anybody who claims that they need the extra couple of horsepower to ride safely and in a responsible manner on a public road is talking out of their arse.
I know riders who on the then current r1100rt police bikes could ride the wheels off some smug cnut on a top of the range sports bike from the same era and unlike the sports bike riders they never made the claim that they were riding gods or needed any more than 90bhp to do so.
