Curious about this as well, how to determine a good appraiser for a classic Honda and what a fair price for appraisal is. Some agreed value insurance want an appraisal, others don't care unless you request some absurdly high value that maybe an early sandcast would justify. Last insurance company I talked to wanted an appraisal despite having a fully documented restoration, receipts, hundreds of pictures, etc. I asked if appraisal typically covered replacement cost rather than market price, as I have a spreadsheet itemizing every parts order (with receipts) and not sure how to quantify a winter worth of labor most nights as I didn't track labor hours. They said appraisals are normally for replacement cost of that specific vehicle, but not covering labor. That seems insane that they wouldn't insure for any labor costs, as how else are you going to get a brand new 45 year old bike?
In any event, whether agreed value or not I think it would be hard to dispute the replacement cost of the bike provided an extensive level of documentation specifically with receipts for everything. They wouldn't have much of a case to offer less than the cost of bike+parts.
