Hi, I have an F650GS, the 800cc twin with a lower spec. I use it is Spain mainly - mostly on road but with with some limited rough surface track use. Contrary to the opinion above I don't find it vibey at all. Quite pleasant and rorty to use in all circumstances and fine whilst standing up too. Plenty of low down torque but not a whole lot of top end - but gets to 100mph plus very rapidly nonetheless. My longest single days run was from Northern France to Moraira in South eastern Spain. 850 miles approx and I can't say that vibes were ever a big problem. I am thinking of the new AT as a replacement as I like the idea of the DCT (I've ridden a friends 1200 DCT and liked it - particularly the inability to stall it at low revs.)
I see the AT as an updated and purpose designed replacement for my current bike with more power - especially for two up with my wife, the DCT box and better off road capabilities - but am not keen on the tubed tyres!
I also have to say that the weight of the AT is a big disappointment. How do Honda manage to add so much of it?
