Glad you are ok. In most states the registered owner is responsible for what that car does. The "Daddy didn't know I had it." is only an out for the insurance agency. Find a good lawyer.
^^^^^ What they said
I would in one way go against the others and say don't rush to get a lawyer.
Have you talked to the dad? Give him a chance to make things right. His daughter, daddies little girl bout killed somebody, you ! If he's any kind of a decent man he'll man up and fix your bike.
leathers all mashed up, first time i wore them too...but they did what they were supposed to....save me serious injury, no road rash.....
big question is.... what to do from this point!!!!
