In addition to my encouragement to buy my DR-Z400SM, I fully endorse your idea to go off the beaten track.
It's awesome and you'll love it. I know I do! Good times await you! Small front wheels dance a bit in the gravel, but are nice on the road. I suspect the XT is quite a heavy bike for learning how to off road on. But if you are are a strong fella (Unlike me) then you'll be okay,
Motorcycling, as you probably know, mostly your headspace and not the machinery. Having said that, a chunky tyre is good when the road the road isn't dry.
