Nice looking HD. Not so much my cup of tea, but it looks great. I wouldn't mind having a longer range bike like a R1200GS or Multistrada some day.
I chatted with a guy in Sturgis for a bit who was on an adventure bike, don't remember what it was, but it had a lot of ground clearance. He had it loaded down with various storage bags and cases. I commented that it looked really top heavy. His replied that is was, "reeeeeally top heavy". I'm gonna guess and say it probably weighed close to my Road King. I would think at some point all that weight on a bike like that would take the fun out of it, especially if you're going to be hitting a lot of dirt roads.
Even with full bags, I doubt the Multistrada weighed close to your Road King.

All good bikes. Just made for different things.
