Given the amount of damage and where is occurred, I would just not even bother... going thru the x-ray exam process worth all that?
Either the car driver's insurance will pay up or you might need to lick your wounds and go shopping...
Rebuild with the remaining good stuff, or part out and get a complete machine...
You have a backup bike? Are you injured to the point of not being able to ride? Do you want to stop riding, for whatever period?
I'd be OK with being off the bike a WHOLE week... any longer and I would have to react...
Buy a bike, and present a bill to the Insurance company (+ med costs) - I'm sure it would be more acceptable for them than going thru litigation.
Ride On
