I just took a look at the 2017 Zero owner's manual and I am suitably impressed.
It certainly is a lot more informative than any similar document that I have seen from BMW or any Japanese motorcycle company lately. That is an excellent manual, in my opinion.
However (personally) I do think Zero is being a bit conservative with their maintenance schedule. I am not sure all of those service items really need to be accomplished every 4K miles - but I guess it can't hurt. The need for that motor servicing continues to confound me.
I would sure like to know what that is about.
In the back of my mind I wonder if Zero is not trying to toss more work than necessary at the franchised dealer's "backroom" to help support their bottom line the way all other IC vehicle companies do.
While that may seem like a good idea to keep the retail dealer's owner busy and continuing to be interested in selling Zero, around here motorcycle shops are selling motorcycles a lot faster than they can service them. Everyone has "help wanted" signs up and there is a lot more work available than there are technicians to perform it - and that is for IC motorcycles. No doubt things are a lot worse hiring qualified technicians to service and repair the new EV technology. However I will admit that most motorcycle shops just can't pay enough to retain a technician so that they can survive in the SF Bay Area. I think I read that the poverty level around here is something like $70K a year. Having an income any less than that and you can't afford an apartment, food or a new cell phone.
