I am not trying to make a political comment, but an economic one. If tariffs go up, so will Zero prices, in my view. And no matter what your politics are, that affects all Zero owners and potential future customers in one way or another. (Used Zero prices might go up, as an example.)
I have visited the Zero factory a couple of times. The frames are made in China and I have seen their shipping boxes. The battery cells are made in a Chinese factory and are assembled into the battery case modules at the Zero factory by their employees. My recollection is that the Sevcon controller is also made in a Chinese factory and shipped here to be installed on the chassis. And I wouldn't be surprised to hear that the fairing parts also are sourced from China. The suspension is made by Showa, in Japan or some other Asian country, I assume. The J.J. Juan brakes probably come from Spain. I think the dash display may come from Thailand. If there are any U.S. manufactured and sourced parts on the Zero, I can't think of any. Maybe someone knows more than I do.
