So I was getting a quote on a 1993 Fireblade today, and the woman from the insurance company told me that they base the rates off of your
a) level of discount
b) Engine cc
c) declared value
that's it....and she also said that 750cc to 1150cc were the same rate and it didn't matter whether it was a cruiser or a sports bike.
You all probably know all this already, but I have to say, it's much different than insurance in Ontario (I lived there for a few years)
