You’re paying for very carefully assembled and QA/QC tested batteries that occupy most of the dry weight and volume of the bike.
Zero sells a much cheaper bike with their own powertrain with the remainder.
Does Zero charge no margin on batteries? Anyway the higher cost of the bike makes premium features cost a smaller percentage, so it's more justifiable adding them and expecting them, not to the point where they become a distraction.
The maxxed-out F850GS is $16,600 with LCD display/nav/entertainment, ABS, stability control, traction control, dynamic suspension, keyless fob, heated grips, cruise control, 125mph top speed, TPMS, luggage mounts, ...
Not that all of it is needed, but throw us some carrots please. Zero, you have 1 week left to add them.
