Low-frequency vibration doesn't bother me; my second bike was a BSA single, and my third a Ducati single. If you don't keep a death-grip on the bars, your hands won't start to tingle, and good old Loctite keeps the parts from falling off.
My 48 is smoother than my BMW at 70-80. The GS has a strange resonating vibration that after a few hours makes my hand numb. The valves are correct, and the bodies are tuned. It's just always bothered me. A lot of people talk about it and it bothers some more than others.
