* Color display that you can customise
Smart phone app?
* Regen breaking on throttle close (like in a Tesla)
Um... check your app settings, it's not as strong as it technically can be due to safety regulations
* More power or a different (customisable via app??) way of limiting the power so that you can properly pull a wheelie on a SR
Available if you change the sprocket on 2017+ it will definitely wheelie have seen it with my own eyes
* Optional low drag luggage option (top case and/or side cases) that fit well into the design of the bike
A Givi top case is "low drag" but not the lowest, apparently we need an aerodynamic tail and no bike out there I've ever seen has this from factory
I am sure that with all the above, Zero can really significantly increase sales and strengthen it's position as a leading electric motorcycle company!
Aftermarket sales will develop for all these things. Zero Motorcycles may gradually upgrade the battery, motor, and controller technology, and possibly change some software settings to allow for aftermarket technologies to push their system limits, but they're not in a business of making a thousand different bikes (anymore).
You have to modify your Zero to get the 2-wheeled EV that you want for less than $30,000 cost. If you're willing to pay more then maybe have a look at other EV company bikes like Energica and Lightning, you might be happier with the stock configuration on those?
