Yes to what the above have said. In addition, the '06 might need the steering head bearings re-tightened, and maybe the front shock oil freshened up. Both can contribute to the feel at speed you reported. But, in general, the new frame is wonderful! Keep in mind the touring frame is not designed to be a Porsche, and will probably never have the trackability of an FJR or an LT over 100 MPH. But for reasonable speeds, it's a wonderfully comfortable motorcycle.
Sounds like you have a BMW, which is a nice motorcycle. So, thank you for your objectivity about HD's.
