I think I understand what you mean.
My CB750 K2 with Ikon shocks oversteer at rear when shaking the handlebars. Feels not safe.
I have the shocks at highest setting, need to lower it and damping 1 step harder. (2)
My other CB750 has also Ikon's but model with progressive springs, also highest setting, softest damping (1). Really stable and comfortable.
Both bikes have steering dampers.
