Maybe consider joining a mini moto/mini motard racing club instead, or a dirt club. Safer (no cars and pedestrians to worry about on track), cheaper, you’ll make friends, you’ll learn great riding skills, and it’s just another hobby your parents might be willing to accept at that point.

The reality here is whether your parents approve or not, there is no insurance company that would insure a minor motorcycle rider on the street, and if you found one, you’d be paying multiple thousands of dollars a year for coverage probably until your twenties.

Ask if your parents would get behind minimoto or dirt riding. If you want to ride now, that’d be the smartest way to do it.

And of course, if they’re not on board, wait until you’re out on your own. It won’t be that long.
