From what I hear, trails are pretty tight there. 80 might be a little too big for that. I've been to crozet, had few damages, mostly from getting hung up or high centered; not sure how much tight(er) the trails are at Gore compare to crozet. Looks like lotta fun though.
Yes Im taking my 80, but not up those trails in those pics!! I know there are some very moderate trails there that I plan on hitting. Mostly planing on some cold ones and watching others tear there stuff up.
Not to scare you away, this happened a few years ago on a moderate trail at Gore. Left rear tire was on a rock that broke, which tipped me right over. Only real damage was $92 for a new tail light. I was lucky.
The trails are narrow, as the others have pointed out. I have always been impressed with the trail guides at Gore, and good camping.
