So, this might actually happen.

advice: train her on a 'disposable' bike. I'm serious, I've been down this road a number of times. 1: not one you like and she knows it. If she drops it, she will feel guilty. 2: if you like it and she drops it, it will suck. 3: if it doesn't stick, no regret selling it.

taught Angie on a gladius I absolutely hated and had almost no money in. she dropped it 2x. no real damage but no one cared. when she was done and passed the msf, she bought herself a super cub. she could have kept the 650 for all i cared but not what she wanted.
I gave the gladius all fixed up back the buddy i got it from. 0.02

+1000. You already know this, but for others who may benefit from a real-world story to be more persuasive than I was.

My wife got the riding bug years ago. I had a Honda 919 at the time. Obviously not new rider friendly. She got her heart set on the 599. I knew a Honda 150 dirt bike would be a much better way for her to learn the fundamentals of a bike. I also knew from past experience what losing half of everything you own is like so...brand new Honda 599 it was. First day riding it in a nearby parking lot and she target-fixated herself right into the curb. Gentle drop, she was fine, bike was scratched just enough to be worth much less when we ultimately sold it because the curb crash freaked her out of wanting to ride.

On a positive note, when she tells the story she usually references that it would have been better for her to learn on the dirt bike, so at least there was learning and acknowledgement
