i am 14 y/o and i am 5 foot 4 inch and i ride a cr 80 expert. I have been riding ATVs and Dirt bikes for a decent amount of time but want something with a lot of power my dad hates the 2 stroke ring but i love power band on them. So if there is a quieter 2 stroke i need to know. but should i get a 150 4 stroke or a 125 2 stroke but what kind of bike.
