Lots of bikes have excessive (by most standards) vibrations. I have ridden big British singles that would shake your fillings out. I have ridden parallel twins with out counter balancers of both British and Japanese designs that would shake light bulbs apart and crack metal fenders and license plates, and I've owned American bikes whose front wheels would literally hop off the ground at a stop light while idling. Certain engine designs have issues with primary balance. It's not limited to manufacture but dictated by design.
