Try Dairyland. For insurance on my wife's and my Spyder is around $400.00 each per year for full coverage. The first year we had our Spyders it was $1400.00 a year with, let's just say the company spends a lot of money onTV adds.
The Spyder won't arrive until next week, so I haven't checked. I use Dairyland for all my other bikes and will start there. From the above post it looks like they will have a fair rate. I've used them for over 20 years and they have always had good rates. Having a clean driving record doesn't hurt, and the age thing has moved in my favor too.
I got full coverage on mine for under $550 per year with my multi bike discount. Either you are not telling us the whole story or you need to have a couple more bikes. I pay less than half of that amount per year for 4 bikes.
I have State Farm on my home and two cars. I have a policy with what they call "stacking" provisions. Consequently, when I checked to see what the insurance would be on an RTS, I was quoted $600.00 per year.
