Unless you stay on the green trails (gravel roads), a big bike and Windrock are not a good mix...IMO. The easiest intermediate trails are Trails 2 and 22 or that's the way it was when I used to go there. I personally wouldn't take any bike bigger or heavier than a DRZ400 there. There's a lot of fun places to ride in the Cherokee National Forest.
Happiness is wanting what you get.
