Another thing to remember. Skills are fine for handling a bike in gravel, but no amount of skill can prevent all those rocks from damaging the plastic. I had a Wing which I loved and put many, many miles on solo. I hit lots of construction zones during the summer in Colorado, Wyoming, and Montana. The thing that was always on my mind was the damage that was possible with all that plastic. I've got a GSA now and love it because I don't have to worry about going through gravel with nagging thoughts going through my mind.
So, I wouldn't worry about the ability of a K1600 getting through gravel sections or even true dirt roads. It might get expensive, but the bike will make it. Heck, if I could get a Wing through some of the gravel sections where the road crew removed the road to its base anyone could ride a K1600 through the same sections.
