Im just going to put this here. https://www.zeromotorcycles.com The only reason(s) I don't have one. When I first saw them in 07 or 08 at Laguna Seca when Moto GOP came back they had no data on the battery lifecycle or a cost for replacement. Another issues was being street legal. Now the times have changed (charged) and it's been worked out but the price point hasn't worked out for me. I did a calculation and good old fossil fuel still wins but Im in the market for a wheelie machine.
