Sharp looking bike, I'm curious how much of a premium the 800 ADV model will be over the regular 800 GS.
Personally I like dual sports for the riding position primarily (easier on my back), and secondary to that is the ability to take gravel/dirt/fire roads with confidence. Everyone has their own priorities, but it's hilarious reading some of the comments about the buyers remorse for a less-than-year-old bike, or others denigrating it with a sniff "My farkles are better than BMW's OEM stuff... pah, n00bs!".
Drink beer, ride motorcycles, be happy.
