I am trying to figure out exactly what I have. The model number is YFM550FWAD which I can find no information about. It has EPS and came stock with skid plates (a arm and full under). I am assuming that it is a special edition of one of the four standard models but which one? I have tried searching the site and found nothing. I've also done a VIN search but that was no help. Hopefully someone here can help. Thanks.
