well me and my friend and his dad finally got to go and i finally had a chance to test the xx out on a real mx track. the track is really 3 different tracks 1 is for mini atvs and dirt bike up to 100cc 2 stroke or 150 4 stroke. the second one is the biggest and is what most ppl use the 3rd was for races and has a 70ft table top ( i cleared it:hey. the xx did great with only a sight bottoming out problem on the front. and it was able to keep up with most of the 450s.
