I had this happen to my prior bike. They totaled it so the value given was based on replacement costs. I think it was some $1500 or so. I opted to buy back the bike and that was a mistake.
They charged some $300 or so for the buy back but the DMV charged about 100 for the new title and 100+ for an inspection. So the cost was 500+ just to keep the bike and I started having trouble after that because the alt went out and a number of other problems.
I could have bought a parts bike for less trouble.
Watch out for things you can't see. My engine was never touched because of the crash bars, but the alt went bad. I guess the impact was enough for something to give or bend.
Be careful what you do. What I should have done is strip the bike of anything of value and let them take it. Then go out and buy another one.
Also, the DMV doesn't give you any discount for a salvaged bike, the reg fees are based on value, the value is 1/2 but they don't adjust for that.
I argued with them after the 1st offer. Came up with receipts for jeans, helmet, etc.. You gear devalues, add up the boots, belt, sunglasses... all adds up. They gave me $50 for a tear in a Corbin seat... There's NO CHANCE you'll get that seat fixed for $50. It's a special type of material that I can't seem to find anywhere. Corbin wants nearly as much for a NEW seat as they do for a recover. The suck part is that I had a nice Corbin with NO tears, now it has a tear and I can't get back to where it was for $50.
You can argue this in court. Get an email from companies for replacing things.
The offer you get might be 2/3's of what they'll settle for. Always argue. You can take them to court, the time will costs them more than it's worth.
It's all about how much of their time you want to spend. The court will give you more than they've offered, but how much time are you willing to spend.
