I love my K bike for touring! However, I wouldn't recommend it for a lot of city riding. It handles great at speed and has all the comforts of home. It is a bit of a pig when it comes to slow speed maneuvers though. If you buy one make sure you really like it because you won't get much for it on the secondary market. There are a lot of dealers these days that won't even trade for one unless they can steal it from you. In my case, I plan to run the wheels off mine. Sure would like one of those new K bikes though!
I am stationed in Germany and have a K12RS and an 1150GS. For all around riding the GS is the bike for Europe. Now for high speed bahn burning the K12 is truley in it's element. It will however kick your ass throwing it around switch backs in the Alps. The new K12S and K12R are significantly improved. If you can get a smoking deal on an RS pull the trigger.
But does the bottle still have the liquid in it? You probably finished it off and you are going to send it to me with a note telling me how you saw God drinking the stuff. OK, you don't really fleece them out of their cash. We all know they give it to you willingly.
