id say start her on a 4 stroke. its a lot more manageable power and if you have an even somewhat built banshee, its more than likely gonna be too much for her. my girl just started riding my 450 here a while back, shes gotten pretty good, but nowhere good enough to be hoppin on my banshee. they are a night and day difference. she has never driven a manual vehicle but understands the concepts. if your girl understands how that works she may be alright. bad thing about a banshee, is when she kills it shes gotta kick start it. its nice when learning to have the push button.
