That's exactly the problem with the Autobahn. As mentioned, I haven't been on it with the V11 yet, but the Autobahn is the reason I bought the GTR. I wanted a bike with good luggage, a shaft drive, and enough kick to keep up with the pace on the Autobahn on long trips. And I like Kawaski.
The fairing on the GTR is so good that you don't notice how fast you are going. I've used the GTR many times to do trips upwards of 400 km. . Mostly, I was on the way to a job, so it's all about getting there, not tourist trips. My cruising speed is generally around 160 km/h ( 100 m.p.h.). One has to keep reminding oneself that it really does take a while to slow down from that sort of speed, and paying very close attention to what is going on is a very good idea. After more than about half an hour at a constant silly speed, it all starts to just feel normal.
Still, it's really good fun to ride on a very well designed and constructed freeway at a speed at which you have to concentrate for the curves.
