Bummer about the bike, glad to hear that you're OK.
Go after their insurance company for full bike value. Show your purchase paperwork as proof. Include all taxes, delivery & set up fees, etc. Basically, give them the full out-the-door amount that you paid for the bike.
I had a similar incident where my K1300GT was totaled within the first 90 days of picking up the bike. Once I showed the purchase paperwork, they gave me full value for it (good thing they didn't notice that I'd added 20,000 miles on it in that time).
Did any of your gear get damaged or scraped? Gather your receipts and go after those full replacement costs as well.
All my gear was paid out in full, as long as I provided either the original receipts, or else showed new retail prices for the same gear (manufacturer websites worked well enough for that).
I also had a set amount of accessory coverage, which worked as long as I provided receipts or proof of cost. That was easy, as my accessories totaled up to more than that coverage was so they just paid me the maximum. I did increase my accessory coverage for the next time though, as it was a small addition to the premium for thousands more coverage.
Did the dealer charge you to do the damage estimate? Turn in that receipt, and get reimbursement for that cost as well.
Once all that is settled and they come up with a better number that includes all of your out-of-pocket costs, ask them what the salvage value is if you keep the damaged bike. Then you can decide if it's worth your time to fix it properly (and immediately add crash bars), or if you'd rather just let it go and get a shiny new one.
Remember, the insurance adjuster's job (especially if their client is at fault) is to minimize payout. So they always start with a lowball offer. Prove your costs, be polite but firm, and don't settle for anything less.
And if you do decide to let the bike go, then please tell me what the salvage value is, as I'd gladly fly over and take it off your hands for that salvage price...
