The atv isserviced regularly like said above. I ordered Royal Purple ATVDIFFERENTIAL FLUID that is in the front and rear diffs. It is the BESTon the market and will not fail. The atv was broke in on it so it willlast. I have a spare quart of it that I will give to the buyer so thatyou can get more when you service it. The motor always has Yamalube ATVoil used in it nothing else.
Please email me if you have any Question.
