yes I bought 2019 R1250 GS Nov 30 . Have 1300mi on it. Owned a R1200GS 2013 ,15, 17.5 with total 97,000 mi. This 2019 is really a different bike. To start at 5mph you are at idle and parking lot speeds are much easier to navigate. The smooth running engine changes your idea of what your speed is. I always knew when I was approaching 80mph , now I'm at 100 and the feedback from engine is the same. I have a 9mi uphill mountain run that I have compared a lot of bikes on. My 2017.5 would come out of the one tight turn at 58mph. Yesterday I came out at 68 mph without trying, yes it is that much better. The suspension has been " fine tuned " for lack of better words. It just works better with engine rpm, brakes, and suspension settings. It now has no dive on hard braking. The throttle also works better in on and off rotations. I did not run fast on the straights and for 130mi I showed 52mpg. At 80mph 3 days ago I showed 42mpg for 140mi. I really like the TFT display.
The cons: the touring seat is good for 75mi. The cruise control disengages on freeway bridge bump with your hand on throttle. The spokes on wheels are loose, 7 in front 8 on rear.
