I have to get full coverage as my bike was purchased with a credit union loan, and I pay about $75/month for full coverage.
I don't know about your case, but Geico, Progressive, Esurance, and State Farm all knew exactly what my bike was, and even had the Military model separate in the computer. Which was nice, because for Geico and State Farm the insurance was lowered for the crash bars (Geico also lowered mine because I installed an alarm, and keep it in a garage).
Basic coverage for me would be about $27 a month, which I may switch to when I pay the bike off.
If these rates seem high, remember that I'm a 21 year old male who hasn't completed college, and you can understand why mine's expensive.
