A car that old would be totaled out too.
You do not have collector insurance on the bike, don't even know if you could have gotten that for it anyway.
Possibly you should have had it appraised and then set the insurance as that for replacement value if you could have even done that?
For classic cars you can do that.
If it's a zero dollar claim, then just tell the insurance you want to keep it as is and be done with it. Fix it yourself.
Sounds like you insurance was only really good for if you hit someone.
