How much does it typically cost for insurance on a 150 CC scooter?

I have State Farm. I pay $6.88 a month for liability on a 180cc Yamaha Riva 180.

Unfortunately that question can't be answered without a number of details, particularly where are you, and what kind of coverage are you looking for. Insurance prices depend on the type of coverage, length of coverage, your age, number of years of driving experience, credit rating, amount of theft in your area, and likely more that I'm forgetting. In a nutshell, insurance companies will charge as much as they can justify.
