I'll add that I rented a R1200RT for a week-long Texas hill country ride a few months ago and came away disappointed. And I really wanted to like the bike since I own a R1100 twin. But the bike was very softly sprung (even with preload cranked up) and had a ponderous feel about it - nothing like the light/tight R1150RT's I've rentedi n the past. While the weather protection and windshield were exceptional, there was just way too much plastic on the bike forward - you felt like you were driving a Winnebago. And the engine, while adequate, was uninsprinng. I like the GT much better.
Truth be told, on this trip, the ST1300 that was rented by one of my buddies was the most impressive of the R1200RT and FJR in our rental group. Exceptional motor and a very buttoned down chassis that had complete control of the not insignificant weight. (The rental FJR had 26K miles on it and was very buzzy, so it didn't compare well. When I got home and started riding my relatively smooth FJR again, I realized that the rental unit was off song.) The ST had only one flaw - the infamous 120+ mph "weave" the various people have commented about over the years. The bike had it in spades and it was extremely disconcerting. If I ever bought an ST, I'd want to convince myself that this problem was solved because it was spooky as hell.
If I were buying today, it would be between the FJR and ST with the GT and RT distant thirds and fourths. I'd probably go with the FJR again because it is such a good value, has more motor than the ST, and is just so well sorted. As someone else has said, it has simple/basic technology, but it is refined and just does everything exceptionally well. My only major complain with today's FJR is the cornering clearance, but this is a problem only if you're pushing the bike pretty hard - which I occasionally do if I'm trying to keep up with my buddies on smaller/lighter bikes.
Then there's the new C14 Concours to think about. It looks like overkill at the moment, but if Kawi has managed to pack more power into a package that doesn't give away any sportiness to the FJR, then how can it not be a player?
