I currently have an '03 K1200RS, which I like very much. However, the later GT's keep rattling around in my thinking. I rode a K1300GT (don't remember the year) yesterday (about 20+ miles of straight and fast and serious twisties up over a ridge and back down) and was, frankly, somewhat disappointed by it. The problem wasn't go power, whoa power, or suspension so much as a general feeling disconnection from the bike. To be fair, the PO had bar backs on the thing (no change to the pegs, though), which, IMHO, are a good way to screw up steering (like touch-typing with chopsticks). Overall, the controls weren't much fun. I kept bumping the high beam every time I tried to fiddle with the ESA. I really, really do like the old turn signal switches. The grips were downright skinny. Finally, the saddle felt like I was sitting on a small (albeit cushy) bar stool seat (the saddle was in the low position).
So the question is, what would I be giving up from the K1300GT to go with a K1200GT?
