Useful for the dealer maybe, if it requires you to visit your dealer to have the updates installed. That gives them some action and while your bike is being updated (or you are waiting for that to happen) the dealer gets to put the screws to you to buy a new and even more updated Zero.I assume only the first update needs to be done at the dealer and after that they are done OTA.
But yeah, I also think the main purpose of these updates is so the dealer can make a little money on maintenance even on EVs. But I will probably have them do it when/if it's convenient for me.
I have both 2017 Zeros here in Auburn. The first step will be getting them both back to Reno, since that house is close to the Reno Zero dealer (Eurocycles).
