My wife started on the 250EX but after a couple of years wanted more power. She now rides a 400ex that is piped and she loves it. She is just barely over 5' tall and she is also 52 years young!

 

Find her a good used 300-350 rancher 2wd. Remember, quads are not cars. One of the worst things about gals, is that their **** get beat to death on these things, an thats where a lot of their complaints will stem from, even though they won't mention it always.
