for who???how tall??? what purpose???and realistically what is the skill level of the rider??? I can recommend a crf 150f for a 16 yo boy with no skill to bang around in a field or put an 11 yo girl on a crf150R and watch her huck it over a 50 foot table top or a 30 foot double...and turn her loose with the likes of Ashley Fiolek and Jackie Ives...
