Ergonomically and handling-wise, the 1200, like the 1150 before it, is virtually without peer. The RT, to me, is BMW's finest bike, and one of the best of any out there for sport touring. Handles like a superbike, but with wing-like comfort. Now for the downside- you specify an R1200RT. That is an air-cooled bike. We say oil cooled/oilhead, but it's really an air cooled bike. Which can lead to problems in stop and go summer traffic (mine eventually coughed up an exhaust valve). They are, as a brand, rated around the bottom (neck and neck with HD) in reliability. So, as far as handling/performance/comfort/ergonomics, I don't think I'll ever find better sport touring bike. But due to repeated and unrelated mechanical problems, a decided lack of a dealer/repair network, and lack of reasonably priced extended warranties, I traded mine in on an FJR. Maintenance for the BMW isn't any more expensive, but repairs are, and are more frequent. I really like my FJR. I miss the ergos and suspension of the RT, but I got more than I gave up when I went Yamaha. The R1200RT is available in a water cooled version (R1200RTW) if you're willing to buy new or almost new. Ride before you buy.
