Here's a thing I'm considering for my Jeep, which is my daily driver, but heavily modified. The classic car insurance writers, like Hagerty ETC, will do an agreed value on classic cars, or modified vehicles. I know that, American Modern insurance is one of the companies who do, "Agreed Value" policies, and that's who insured my bike at the time of my crash. I'm keeping the policy in effect, and also plan to explore the agreed value thing on my next bike.
