The 800 IS NOT (IMHO) EASIER TO RIDE OFF-ROAD!
The R1200GS clutch is like a tractor. It requires MUCH less precision off road than, what I felt to be, the more sensitive 800 clutch. The 1200's clutch is absudly easy to modulate, it's CoG is low, it chugs along nicely. I found the the F800GS's clutch to be MUCH more sensitive, as soon as the clutch is in all uphill forward momentum is lost, it feels tall and it is harder to upright when laying in dirt.
But, I have seen the 800 do amazing things in the right hands. I just think that the 1200 is easier for novice/mid-level off-roaders.
