My 93 Honda ST1100 costs $175 per year for liability through my regular ins Co (Shelter).Shelter Ins wouldn't even cover my 04 Suzuki Katana 600. They don't insure "sport" bikes (even though it's a sport cruiser). I had to go through Progressive for it. It costs me $76 per year for liability. For full coverage, it would cost me approx $790 per year!!!
Both bikes are paid for, hence the liability only and I can afford to pay for a collision if my fault (medical for myself & passenger + the other person(s) if required. If you have a lien on your bike, keep it parked outside or are not "experienced", I would suggest full coverage.
Anyway, go online @ Progressive.com and input your info. It's free and instant quote along with other ins co's rates.
BTW...I'm 47 yo and insure my home + (3) other vehicles with Shelter.
Good luck
