How much a motorcycle insurance cost in ga?

You cannot estimate rates on a forum like this. Far too many factors are used by insurance companies to compute rates. Some of these are state, county, zip code, driver age, driving record, prior insurance, experience driving, type of vehicle, type of coverage, and many more factors. I have written motorcycle insurance in Georgia for as little as $30 per year to as much as $4000 per year and my office is in the country not Atlanta. If you haven't bought a bike yet I can tell you that a "crotch rocket" is several times higher for insurance than "cruisers". I have a almost new Kawasaki Vulcan Classic cruiser and my full coverage is $160 per year. I suggest calling an independent insurance agent who can compare several companies. I represent 4 companies that specialize in motorcycle insurance.
