A couple or 3 weeks ago, I test rode the 6 spd 18 GW. I really wanted to test ride a DCT, but they didn't have one ready at the time. The test rid e I got was a 4- 5 mile around the block ride. Not really enough to feel her out thoroughly. I am only 5'8" so the fit feels fine to me. However, I wasn't overly impressed with the bike enough to buy it. I mean, if I didn't have all the money invested in suspension, audio and other stuff on my 13 F6B, I could see being a little more tempted. But knowing there are complaints about the GPS and some other criticisms I've read, I'm pretty content riding my F6B. They're supposed to call me when they get a DCT for me to test and said they'd arrange a longer test ride.
I did test ride the K1600B. Test rode it for nearly 2 hours and got to take it on some twisties. I liked the performance , at least when you get the tach above 4 grand. Below 4 grand, the GL 1800 has it beat for sure. But you keep the engine with a few more revs and she really moves along. I incidently lifted the front wheel through the first 3 gears, just accelerating hard. On the highway, the K1600B does not feel as planted as the GW/F6B and seems to get buffeted around easier. One thing , by the end of the test ride, my left knee was starting to complain and the handlebars would need some help. The K1600B would need some $$$$ spent to make it an all day rider for me. Getting back on my F6B, which I have already spent $$$$ on comfort, felt like coming home to my recliner after a long day working.
The BMW dealer called and has a GTL for me to try. I've been really busy and haven't had chance to get back yet. I think I'm over the new bike bug for the moment though.
