i have never owned one, but i have driven an older and pretty used one before a couple of times. they really arent bad in performance. they have enough power, but the size can get kinda cramped if you are a big guy or something. the one i drove has a FMF exhaust on it but thats it. it has enough power to keep me happy, but its kinda small, and i think that i would enjoy a little more power of like a 450. warriors definately not a bad choice though. IMO (in my opinion)
EDIT: are we talking about the bike warrior, or the quad warrior?? haha i must have gotten confused.. my bad!
