Hi, I am new here, having my SR MY2018 for a week. First impression - AWESOME ! 
But... during my trip back home I rode the battery to 0% and had 175km with 48Wh/km = 8,44kWh used. Well, the dealer said it will go up after few battery cycles. After 2 more cycles nothing happened, I am able to get 8,5kWh from the battery only. Is that normal? Are they right?
Second problem is a noise comming out of the belt, more precisely from the gear of the motor. They are also telling me it will get better...right?
Third and the most serious problem - the bike makes restart when I stop at the lights. Does not make it every time, but very often. Don´t have to tell you how dangerous it is ! Does anybody know where is the problem?  I went through the log and found this error coming up during the restart again and again:

Thank you for your ideas...

I will say the wh/mile that the bike calculates is always way too low to multiply it out to get your full battery capacity.  Not even the nominal capacity.  Not sure how it's being calculated but it is definitely off.  You can use it with precision to measure one ride carefully to another, just the number itself isn't accurate.

Not sure about the belt noise, just make sure your rear axle is straight at the same marks on both sides to make sure the belt is tracking straight.

And the faults look like there is a problem.  Did it rain the day you rode the 175 km? Or did the dealer wash it with a hose before you bought it?  hopefully that's all it is and it goes away once it dries out.

[Walker]

Thank you Terry. 
So how can I learn the real capacity of my battery?
I´ll try to align the belt, but is seems to be ok.
There was no rain since I got the bike so water is not the issue...

I think the Zero app is fairly accurate regarding total battery kWh capacity when fully charged.  It seems to correlate fairly well when recharging and connected to a Kill-A-Watt meter.  The meter will show about a 5% larger draw from the wall outlet, but I chalk that up to the charger's inefficiency that turns some of the electrical power into heat. Plus, the cheap Kill-A-Watt device is probably not perfectly accurate.

I had serious problems with Zero App version 1.6.71 which gave me bad data.
I reverted to version 1.6.50 which works much better (at least with my bike: FXS 2016 with firmware 47).
Perhaps you could try this version...
You can get it from here: https://downloadapk.net/down_Zero-Motorcycles.html

Of course, it will not solve the problem that you seem to have with your bike (third problem in your list)!

Maybe a bad contact within the keyswitch? due to water ingress or defective build. If it repeats under "dry" condition, it should be replaced by dealer.

[Walker]

So I am in a contact with my dealer and with ZERO Europe HQ and they call me to have it repaired. They say that  the errors are referring to the communication between the MBB and the controller, probably have to change it. How could this pass the factory tests?

[Walker]

So the controller is being changed...

[BamBam]

As for the belt noise, loosen up the belt a little bit. I always keep mine looser than the factory spec calls for without any issues. Adjust the rear wheel so that you have at least 1/16" gap between the belt and the outer lip of the sprocket. Spray some silicone on the belt and on the motor sprocket area. That should quiet it down. The noise will also diminish over time.

[Walker]

Ok, I´ll try. And what is the default "belt frequency" for 2018 model, 42,5 - 73,6Hz or 96,3 - 124Hz ?

[BamBam]

Sorry, but I have no idea what you are referring to by belt frequency.  Maybe someone else reading this thread does.

[Richard230]

Ok, I´ll try. And what is the default "belt frequency" for 2018 model, 42,5 - 73,6Hz or 96,3 - 124Hz ?

42,5 - 73,6Hz , per page 6.20 of my 2018 Zero S manual.

[Walker]

Thank you, I tunned it to 70Hz.  Few day ago I got my bike back from the dealer. They changed the controller unit and made some "calibration". Now the bike does not restart and runs fine. But I am still woriied about the range and usefull capacity of the battery, Richard230 or someone else with MY2018, how much energy can you get from your 14.4kWh battery pack? I am still at some 9,5kWh (last trip 216km at 44Wh/km).  I also got a notice from the dealer about battery-controller learning proces - see attached file.

[BertTrack]

Nice. I have noticed myself that using my bike for long rides will improve the expected range. But if you're on the road and "quick" charging it the expected range will deviate more. On my FX atleast.

Before Zero's latest BMS and MMB version 31 updates, my 2018 "16.6" kWh S was showing 15.183 kWh capacity on the Zero app when fully charged.  However the latest version 31 updates have eliminated that information.    I assume that this was done to keep Zero owners from asking questions like yours.    Now the only way you can check your battery condition via the app is by checking voltage and cell balance (which on my bike varies between 2 and 3 mV right now) - and of course relying on the percentage shown on your instrument display or cell phone app.  Apparently, Zero is slowly reducing the amount of battery condition information available to their customers via the app.  Kind of makes you wonder why. 

My thought is that Zero is slowly reducing the battery high and low voltage parameters in order to extend battery life.  My 2014 S (which showed 13.38 kWh when fully charged and when new - if I recall correctly) originally would show 117 volts when fully charged and 0% represented a completely discharged battery (no reserve).  However, the 2018 model originally was showing 116 volts when fully charged, but with the new firmware update it is now showing 115 volts fully charged. I have no idea what will be going on as the battery pack reaches 0%, since I have not taken my battery below 25%. However others have reported that at 0% on the display, you can still ride another 20 miles, or so.

When my 2014 S first had its "power tank" installed by my dealership, it also showed something like 9.5 kWh, so I complained.  As it turned out, a Zero tech came to the shop to analyze what was going on and determined that the power tank was defective and that its individual BMS was not communicating with the bike's MMB.  He replaced the power tank module and everything has been fine ever since - other than the total battery pack, after three years of working perfectly, started to stop charging the battery to 100% and now stops charging at 92% and 113 volts.
