I have state farm, with 6 sleds runs me about 250.00 a year for the bunch. I am 28 clean slate and no claims. But I have everything from my business to my home insured with them. So I get a pretty good multi policy discount.
Working in the autobody trade I can tell you which companies are decent and which could care less about their customers. State farm good. Farmers, progressive, Esurance not so much...
Biggest Deal with sleds I've found is who will let you put stated value on your machine I have 15,000.00 on my Dragon still because I have all my ducks in a row and cataloged each and every aftermarket part on my machine with a list cost from WPS plus high blue book on my machine = total cost for me to replace her with an exact twin if something catastrophic happened. Costs me a few pennies a year more but its comforting knowing I would not have to be riding a ol wedge by the time the insurance adjuster got done finding excuse's to devalue my machine.....
When you go to get your quote have them tell you what they will pay if your sled was a total loss, then think hard is that amount even half what your mods cost you?
Catalog and List price on a sheet every single Mod or add on your machine has sign it and have your insurance company put it in your file when you get your insurance on your machine so that way they can see you are serious about the value you are placing on your machine.
Hope my rambling helps you out
