I honestly can say in the 3 yrs that I worked a parts counter at a dealer, I have never once had someone refer to the banshee as a YFZ-350. Most of the time its "89' banshee" or "95' Banshee" .
Since your in such a infomative mood... actually you forgot a digit in the model number. YFZ-350N or YFZ-350P or YFZ-350L or Ect.....
