Check out Dairyland. I'm currently insuring my Wing, Strom, KLR, and Scooter together, for only a touch more you were quoted. Since we're both in IL, I'd think your quote on the KLR would be $130 or so, depending on your age and driving record.
I have my bikes with Dairyland, and the rest of my stuff with State Farm. State Farm has always been double or more of what Dairyland has quoted me.
Also, if you're an AMA member, or have taken the ERC course, be sure to mention it for the discounts that comes with them.
If they don't work for you, check around.. There's some deals to be had with some of the companies.
