Well I have found that to be the opposite. Johnson quoted me the best rate, something like $500 below the next best rate from TD. Now I got a professional association discount (school association). I ride a cruiser and they had it in their systems, and is well over 750cc's. They did mention they do not insure super sports. Otherwise the service was better then most insurance companies. I tired Riders Plus, I always do, but they always want to put me with Echelon and the rates are much higher.
So how is it not bike friendly? Seem's insurance is just luck of the draw, nothing to do with being friendly. Put the insurer, your area, your bike, and experience together, and call around and see if you come up lucky with a decent rate.
