A 4 wheeler. LOL. I don't have a clue. It was used, and I traded some used stuff I had for it thinking it was a honda (had honda stickers all over it) took the fairing off to paint it..............no name, nothing to indicate a name, or model number, but if you search ebay for parts for "china 50cc atv" the parts it shows look just like what she's riding. So it's some kind of off brand chinese piece.what is it your daughter is riding???
