Hmmm, maybe I better check with State Farm, too. My bikes have been super cheap since I've been in Montana, so I can't complain about price. But the way they right up the policies, they treat each one as an individual policy with no multi-bike policy like some have (with the train of thought that you can only ride one at a time). Granted, they don't know WHICH of the ones you are riding at a time (could be the one with the highest insurance rate), but with my vehicles, they have always given higher and higher discounts the more cars I have on the policy. As a matter of fact MANY years ago, I had a thunderbird with full coverage. I found out that adding an old beat up pickup truck to my policy gave me enough of a discount that the car AND truck cost me less per year than only the car. Funny how all that insurance stuff works.
I've lived in states where they gave you a motorcycle policy option where you are not covered, or allowed to ride, for several winter months. I never did it because there were always those few nice days where you got out and enjoyed it where all my buddies were kicking themselves because they couldn't ride.
