Q: Which is the diameter of the piston for ARTIC CAT 300CC ATV MODEL 2004
Over 5 years ago

A: I am unsure of the stock bore diameter on the 2004 Arctic Cat 300. Unfortunately we are not an Arctic cat dealer so i do not have access to those specifications. What I can say is that I don't show any aftermarket pistons available for your model so more than likely you will have to contact an Arctic Cat dealer to obtain the piston for this model.
