What kind of dirt bike should my friend get ?

[HS]

my friend is 5 5 and she wants to start riding what type and size dirt bike should she get.

[rockbase]

whats her inseam, how much does she weigh, how much riding hs she done, is it woods, mountains or fields.
If shes new, she should start out small. Go to local dealer and sit on all the dirt bikes, it has to fit her before she can even consider other things like style, cc size etc.
