(usual disclaimer first)
I've been in risk mgmt. for well over 20 years. That doesn't make me an expert, but suffice it to say that I've been involved in hundreds of insurance claims (if not thousands).
Your insurance's objective is not technically to pay you the least amount possible. Their DUTY is to pay you based on what your policy says. So I'd start with reading your policy - not the declarations page, the ACTUAL policy. Doing so tells your claims adjuster that you are going to hold him/her accountable.
You will probably learn that your policy says it will pay to repair your vehicle (bike) to pre-incident condition up to the Actual Cash Value (ACV) of the vehicle. You will probably also learn that your policy says if the cost of repairs (meets or) exceeds a certain amount (usually 75% of the ACV), then the vehicle will be totaled and you will be paid ACV, less deductible and salvage value if you choose to keep the bike. Your underwriter has a right to salvage what is left of the bike and retain whatever they can get for it. If you choose to keep the bike, your insurance proceeds will be reduced by whatever the going rate is for salvaging that bike. I'm explaining this because if you are so inclined and a little motivated, this may be an excellent way to recoup what it is REALLY going to cost you to replace the bike. You may give $200.00 for the salvage value, but thanks to the marvels of Ebay and the like, you could sell parts that total 10 times (or even more) that amount. Consider that.
How does your underwriter determine ACV? It depends on what the policy says, but in all likelihood, they have discretion in their favor. You cannot always go with KBB or NADA to determine ACV - especially with motorcycles, in which their value varies greatly by geography and even season. Your adjuster will likely look at similar bikes for sale in the area where you live - dealers, craigslist, cycle trader, etc. He/she will hope to get at least two "comparables" and from there, run the analysis to include adjustments (plus or minus - goes both ways) for things like mileage, condition, etc. In that light, be sure to bring up things that your adjuster might not realize. For example, if you just installed $500.00 worth of tires on the bike, make sure that is known.
You may have "accessory" coverage on your policy, which pays (up to a limit) for your riding gear and installed accessories for the bike. In general, these are valued at 50% of their original cost (usually what YOU paid for it, not "msrp"). Having been through this, if the accessory is still in good working order, and can be installed on the bike I am replacing it with, I prefer to retain it for myself - just tell the adjuster that you will be removing "x" and "y" and retaining it. There might be some strings attached to this, but there is enough wiggle in the policy to deal with it.
If you have towing coverage for the bike, and you didn't pay someone to move it from the accident scene (i.e. you handled that yourself), ask the adjuster if he/she would allow some reimbursement to you for this expense. Again, depends on the policy, but it couldn't hurt to ask. Might get you another couple hundred bucks.
Hope this helps.
