I've taken my KLR a few places I shouldn't have, and I can only imagine how much fun a nice small dirtbike like that could be!
I was just out at the ORV area at John Redmond outside Burlington last weekend and took a spin down some of the trails. We saw at least 7 or 8 trailer loads of dirt bikes and quads come in and out while changing a flat! Seems like a popular area.
