Its got to be the aerodynamics of the bike from front on. I was experimenting by tail gating (with enough room for emergency stops) a semi yesterday, and even my body was being blown around quite markedly. The bike must have a very turbulent frontal aspect. I agree, it's the most unsteady ride Iv'e ever had out of five Harleys and other bikes as well.
Just get use to it is all I can suggest.
Best wishes.
