Most all insurance companies today cover motorcycles and offer motorcycle insurance.
I have my motorcycle insurance through Geico Insurance company and have been very happy with them.
You can go to Geico insurance website and get a free motorcycle insurance quote.
I pay $580.00 per year for my motorcycle insurance which is pretty reasonable but your costs may vary so you'll need to get an insurance quote for motorcycles for yourself to get your cost.
A few other insurance companies I know that have motorcycle insurance are nationwide and progressive but many others do as well.
