Was just about to reply but ive an R and never ridden the X, but did have a test ride on both models of the versys, good spread of power and it likes to have a wee race and a rally if you want to.
There should be a few people who have taken them off road as they offer bash plates etc for them, but as for the extent of there off roading i wouldnt say it would be anything great, maybe a wet field with a bit of mud or the odd rough stoney path at walking pace. The suspension is just too stiff for anything more than walking pace, saying that on the road its perfect (i just found it a little too small).
You should be able to fit a set of Avon Diztania thingys to the bike, would give it a start to some off roading feel, i think you can also get TKC80's in that size or something similar but what they would feel like on/off road ive no idea
