just read the post again and saw the part about sand, the 300 i have doesn't get my daughter up all the hills we ride she comes in at 75 pounds, my son is 90 pounds and the 400 goes anywhere, and he thinks it's the best,

Glamis or Gordons Wells = at least a 400ex.

i suppose if its strictly sand,,,,,,,,the 400 would be a must

90 lbs? If she is a beginner rider then the 250ex would probably be better. If she has been riding a little then the Raptor 350. Does she want to use a clutch? (300ex too)

The bike will be for the dunes and the dirt. I dont want here to feel handicapped in the dunes though. And the clutch is not an issue she can pick the up real quick.

Either the 300ex or Raptor 350 might be good. She should probably take a safety course.

i would get her a z/dvx/kfx 400 if you do other riding rather than a ex because of reverse
