Well, my 9 year old son just graduated from our Motoski Mirage (after he blew the motor) to my Zr700.. But he`s been riding motocross for 4 years now and can outdrive some adults. Dont even waste your time with a 120. Not saying a 700 is safe for ANY kid(other than a straight line on the lake). but atleast get a Z370.
