Whoa!!!!..... Have you ever rode a dirt bike before? First of all you don't need any of the bikes that you have suggested. You need to start with a Honda CRF100F that will be plenty of dirt bike for you and you will still be able to hurt yourself because just by the way your talking tells me "You know nothing about dirt bikes".
