Are there any Insurance agencies that will not ask for outrageous sums of money for a 20yo on a sportbike?

I am looking at buying a GSXR 600 and you would think that I am looking into a Ferrari from these quotes. Are there any companies that are reasonable? I have check mostly the big three for bikes- Geico, Allstate, and Progressive.
Also If I put my truck with the same company does the multi-vehicle discount take off much.
