350 Freeride is street legal here in Europe - it would surprise me if it isn't in the US..?That KTM 350 looks awesome. I really want a street legal bike though so that I don't have to trailer it to the nearby trails.
A couple of years ago I had the chance to take one for a long test ride in some serious terrain - I've never tried any other off road/enduro bike that made me look so good It was almost like riding a MTB.
