I was on a ride home one windy day, and experiencing quite a bit of handling difficulty on the CTX. My riding partner that day was on his 1600B and said he noticed my problem, so he offered to swap for a short distance, just to see if it was the bike or me. I don't know whether it was the extra weight, or the larger tires, or whatever, but the 1600 was much smoother in the gusty crosswinds. My riding partner also noticed more sensitivity to the gusts on the CTX. Since then, I've had the opportunity to ride a different 1600, and a new 1250RT. They both handle way better than the CTX.
To help in those gusty crosswinds, I took off the top box, and noticed a difference. I had the Bestem 929 mounted on the rear carrier like most everyone else. Since then I bought another rear carrier, that I'm modifying to fit facing forward, over the pillion. I'm not going to use the top box all the time, but when I do, it will be in the slipstream, directly behind me, instead of hanging off the tail like a big rudder. I can do that since I never ride 2 up. I also took off the Cee Bailey windshield to see what effect that would have, on a windy day, and that too improved the handling in gusty crosswinds. I'll probably run the rest of the summer with the stock windshield in place.
Back to the Beemer...
Love the handling of both the 1600B and the 1250RT. If I was 10 years younger, I'd probably swap tomorrow. One thing would really sway me, would be a DCT on either one. The clutch is OK on the open roads, but anywhere that I'd have to be continuously gripping and releasing would be painful for me. "What a drag it is, getting o-l-d."
