Brand new never used for 525xc (may fit others,check FCI web page). I have attempted to put it on my quad though. I am a novice mechanic and recreational rider and this thing is made for experts. I read as many threads about this thing as I could before I bought it. After playing with it for some time I just didn't feel comfortable putting it on and using it reliably. So I am selling it and asking $250 and I'll ship it free within the U.S.
