having gone through claiming my 07, RIP, last year and having a really good friend for my agent I can tell you for certain that it might not be a bad idea to have a list. Most companies, even State Farm, will cover some farkels upto a point. SF covers upto 1.5k unless you get more coverage. This does NOT include helmet. They cover Helmet anyway.
However, What sometimes happens is depending how much you have on the bike and what your bike cost at the moment and what they are planning on giving you. You might be better off stripping your bike and just take it what they give you.
Such was my case. They offered me X amount period. I asked if it included farkles and was told no. If I want to include them they would call dealers and see what my bike could possibly sell for in reality if it was not totaled. At that point, hell I did completed 1st grade and can count to 12, I said hell no, write me a check NOW.
I took as much as I could off the bike. gave them my title and took their check.
I am not aware of any insurance comp that doe NOT cover the helmet. Some, cover ALL of your gear.
So, it might be good to have, but might not need it.
