Hi Im looking into buying a 04 crf 450 I was told it is a north american model. I live in New Zealand. I dont want any problem when I go to buy parts for the bike, so does anyone know what the differences are between a north american model and model we get (im assuming its a Asia/Oceania model) . Im really confused. One person told me there is no difference between bikes other countries get. Is this true , or is this just salesman bs.??
