sounds like an okay deal to me. those retards are gonna be on the street whether she's on a 250 or a bicycle - something we all have to deal with.
and maybe you should pay for her track days.
I'm thinking car vs motorcycle, I've been teaching her how to drive a jetta diesel manual tran for a while now, when she starts to drive that will be her car.
She can do "track work" and get free track days, also part of the reason she has to agree to take on all of the expenses is to learn the true cost of owning something, just because you bought it doesn't mean your done.
Now, with that said there is no rule that mom and dad can't buy things for birthdays and christmas and such, but you gotta make them sweat it out a little otherwise nothing gets learned.
i think you are going about it just fine. its going to be difficult to enforce it because kids can be unpredictable. i think she will have her head on right for this so i wouldnt stress too hard.
Thinking about the shit that I got into as a teenager is part of my hesitation, she is a good kid, straight A's head on straight but at the end of the day, a teenager is a teenager. If I had a motorcycle as a teen I'd be dead, no doubt in my mind, but that's me, I was an extra wild variety.
Thats why I also said, for now, rides with mom and dad only so I can supervise, when she decides to pull a stupid teenager move when she is out of sight, I'd rather have her do that in a cage.
When she gets older with more freedoms, I'll just have to cross that bridge when I come to it. This wouldn't be so bad if I wasn't so damn bad as a teenager, I know what they can get into, cause I was doing it and more, hehe
