It all depends on the insurance company. Some base it on CC's regardless of bike type (why the 1600, 1800+ cruiser are expensive). Some base it on the type and could care less about CC. i.e. Sportbike...anything GSXR, CBR, ZX-xR, YZF-R, etc. means big bucks....again, depending on the company.
This is also based on FULL coverage, they are all cheap for liability only...
To give you an idea I paid $206 for full coverage on my BUSA through USAA in Ohio, same coverage in TX is almost $600. Keep in mind USAA doesn't cover new policies so if you call them now you go through Progressive. Progressive quoted me $4,000 for 6-months with the same coverage I have now...:lolguy:
State Farm was the only other company that could get close to my USAA rates and they wanted more for my cars!
