I bought a T800xc cause I thought the 800cc size would win me over...best of both worlds being enough for the road, and not too much for off road. It is a great bike but ultimately a bit underwhelming...it is not enough on road ultimately and is still too heavy off road.
I bought a 1190 adv R and it is nuts on road and off. Totally different league to the T800xc....which is now for sale. The 1190 is too heavy off road, and too powerful, but it is so capable it is ridiculously fun. On road it is simply awesome.
