If Zero provides substantial upgrades, folks like me will trade in or sell and upgrade immediately. Other than the top heavy charge tank, and the incremental upgrade to the 14.4 battery pack, changes have been basically nil for a few years. New colors, mainly. This owner hopes that soon ( but not 2019, alas) Zero offers options that pretty much every major moto manufacturer in the western world offers, even scooter company Vespa for crying out loud!: traction control, for sure. Cruise control, TPM, ambient thermometer, fairing, real windscreen, heated grips, options to place the bars into a truly upright touring position ( they shortened the cables in 2018 making that impossible on my S, WTF?!?). Check out semi active suspension on a BMW or Duc. It will blow your mind. Yo Zero, are you listening? People aren't buying Zeroes to save money, at least in the US. Make a better moto and we WILL buy it.
