I tried a few:

1) Geico = Not bad, but nearly double Progressive on my '01 F4i. I actually used them for about 1 month before I got my in-person progressive quote. They were at $960/year for my '01 F4i with Comprehensive and Liability

2) State Farm = Crazy High (even though I have my cars and condo through them). They wanted $770 for just liability on an '01 600CC bike (they dont take into account it being an R6 or 600R, just the displacement).

3) Farmers = $1k+ for Comp and Liability on the F4i

Now I am with Progressive. They were $480/year with a $50 deductible for the F4i for Comp and Liability. Now with my '07 600RR they are at $780/year for Comp and Liability with a $250 deductible. I havent shopped around since getting the RR, but I assume they are still going to be the lowest based upon my previous comparisons.

FWIW, I am newly 23 (22 when given the above quotes), unmarried, with a clean record for 3+ years.
