Having had a few bikes burnt that were only insured third party, I have now had my bikes valued. In France, that entails seeing an insurance expert who in my case came to my place and spent half a day taking photos and notes and a month later sent me a very complete dossier for each of the 7 motorcycles he looked at. I was pleasantly surprised, he must have spent a lot of time scouring the auction results worldwide. This was then forwarded to my insurer who insures the bikes third party, fire and theft for the value the expert indicated.
The valuation cost me €700 for the 7 bikes, insurance costs me €650 a year. The 7 machines are valued for about € 115 000.
