They're fantastic bikes, I've had one for a couple months now. They're extremely light and handle like a dream, they make incredible horsepower for their displacement and emissions restrictions, and they have really nice ergonomics.
But I wouldn't even consider using it for any sort of 'adventuring' though - they're not built to withstand long maintenance intervals, nor would I expect anyone to start manufacturing 'adventure' accessories for it.
There are already reports that the top end doesn't last very long on these bikes. People with the R model are already talking about short ring and piston life.
Of course, everyone's idea of adventure differs, and since you're posting here I would imagine you are interested in it. If your idea of adventure is spending a day or two trailriding, then it would probably do just fine.
