The K1200RS rider must have been really enjoying the ride, since that's the only reason for them to be lumbering behind the lifestyle riders...
I love my K1200RS. I think it's nimble, but you absolutely *must* get the weight distributed evenly or else that big bike pushing back at you all ride long gets rather tedious. Mind you, the only other bike I ever rode was a Ninja 250, so take my experience for what it's worth.
It's great for 2-up but I would definitely recommend a saddle mod. The stock saddle is not so great for 2-up. Really barely sufficient for 1-up. Mine is disintegrating and I'm really looking forward to its replacement :)
