Max, the K1600 has the same basic HP and TQ as our 14's. Beemers have lots of bells and whistles on them for a higher price, compared to ours. The main positive for Beemers is that they handle better/more neutrally than our Kawi's, at speed. This I know, after owning four of them. Extremely flickable in the twisties, and the weight factor disappears above 10mph.
On straights, the R's are left behind a 14. Both K's are pretty equal with acceleration. In the twisties, the R will leave us in their dust, and the K's will run neck n neck. On along straight, we leave the R's way back in our rear view mirrors. Done it many times.
I love riding my R, for the above noted and other qualities, but the 14, is such a muscle machine, it raises my testosterone level 50%, when riding. At my age, that is a God send. . .tp
