Zero Motorcycles Forum | 2013+ / Re: Ceramic bearings
« on: July 03, 2018, 07:39:12 PM »
But having the bearings in my motor fail around 10k miles points out a serious flaw in their design for long term use ... at least in a motor with exposed internals and with 10 kN higher tension above stock ;)

So while the bearings were subject to near constant axial forces they didn't experience sudden jolts a wheel would experience. That said ... if they were such a bad idea for wheels then they wouldn't be able to sell them nearly as much as most motorcyclist are cheap bastards who flinch when they have to replace a 0.10$ part :D


I'm in the sad position where my motor bearings seem to have worn out. There are 2 reasons for me to suspect this. Firstly there is a slight noise coming from the motor and secondly I'm able to slightly move the pulley up and down by hand. Plus the motor doesn't feel as punchy as it used to. My local Zero dealer have proven themselves to be a bunch of scamsters, so I'm left to my own devices. Is there anywhere that I can find more motor info? Is it even possible to replace the bearings yourself, or do I need to find electric motor specialists?
This is all I have so far: http://motenergy.com/mepmbrmo.html

Thanks for all the replies. The 100% electric sticker was put on the bike by the dealer effectively making my bike a riding billboard for these bikes. It doesn't look bad so I don't mind. As for the Gates app, I've tightened the belt a bit and as you can see, plucking the belt gives consistent results. So I guess this could be a quick and easy way to check.

Hi, just thought I'd try my luck and ask if anyone has used the Gates tension app to check their belt. I've recently changed my bike to the higher speed gearing option and I see the Gates app only makes suggestions for what the frequency should be for mountain bicycles. Nothing on the unofficial service manual either.

Yes, grmarks, it is sold as for bikes on a bike web site. I've unplugged and re-plugged and the past 3 days riding has been problem free. I think it is probably some glitch with the computer. Does your bike not feel slightly less quick since your xenon light? I like your installation idea.

I've fitted a typical plug and play Xenon light on my bike this past week end and so far the results have not been encouraging. The electric motor on my 2013 S suddenly stops working after 10 to 20 minutes of riding. This is very bad if you are at a traffic light and the bike suddenly can't pull away. I've not had the problem where the light stops working though. The old halogen light was rated as 12V and 55-60 watt, the new HID light is rated 12V and 35W. I've guessed that the bike's computer must pick up some error during the ride and stop the motor, for some or other reason, but the exclamation error icon on the dash isn't flashing as it should if there is an error. The old on/off reboot gets the bike moving again after this problem happens. For my commute today I unplugged the high beam cable and switched the highbeam on, effectively switching the light off. It seems like using HID lights are bad on a Zero.

Yes I did, and I know for a fact that no Zero that hasn't been heavily customized goes any faster than 103MPH, so the criteria that you describe are entirely out of bounds for considering use of any Zero at all let alone having to decide between a 2013 S and a 2014 S.


He said heavily customized  :o

I think a fx with the 98 in the rear can go faster than 103 but what do I know my speedo said 75  ;D

So you thought DynoMutt was suggesting that the dealer would be using a heavily customized bike as a demo? I'm not convinced that he would be that stupid even if he somehow managed to jump to the conclusion that I live in Zimbabwe.

Well then, I've decided to go for the 2013 S. The dealer is asking the equivalent of 7900 USD. Maybe I'll make a quick video then to show DynoMutt that the bike can reach 121mph. Like the next guy I don't like being called a liar.

You will have a problem going more than a few seconds at anything above 130km/h, and the S models will never touch 160km/h unless you're going downhill.

Did you read my first post? The top speed was 195kph or 121mph. And after about 20 minutes of putting the bike through its paces the bar was still indicating that the bike is fully charged. But the weather here is still a bit cool at about 34 deg celsius or 93 deg F, so maybe that helped.

Thanks for the stats Burton, for me that translates to about 100km at 100kph.

Thanks for the good advice guys. The 2015 models will only be available in July next year (this side) and that makes them completely unaffordable since our currency is predicted by most economists to be on the verge of a Zim style free-fall. At least after more than half a decade of stealing public funds our president's more than 800 corruption charges are about to finally catch up with him. Maybe. Always look on the bright side. I'm more worried about our nuclear project with Russia. If Putin manages to get nukes here it would undo all the anti-missile efforts of the US. Way off topic again, sorry.
If the 2013 S is a solid bike that would allow me a commuting range of about 100km / 62 miles, and save me from the robbery at the fuel station then my choice is obvious.

Hi everyone, my first post. Hopefully there will be many more after I've made my mind up. At the moment I have a choice between a brand new 2014 S and a demo 2013 S. The 2014 model has the same price tag as a new BMW F800 (BMW being the benchmark for overpriced bikes this side) while the demo is less than half this price. I've taken the demo for a test ride along with a 2013 DS (also available at half price) and I was very impressed. The bike felt a little soft compared to the DS which was a good thing since the roads I tested the bike on was pitted and potholed with gravel and sand in random places. The acceleration was great and the bike was doing 195km/h in no time. Of course range is the biggest concern and can't be checked with a 20 minute test ride, but speed is also important and can save your life. For me the biggest difference between the 2 models is the power tank. From what I've heard you could in theory upgrade the 2014 model with a 2017 power tank some day, but with the 2013 you don't have any such options. For me this bike only makes sense as a commuter that saves you money in the long term. So I'll need it to be able to do an 80km daily commute at speeds ranging from 60km/h (when the traffic slows to a crawl and I filter through) to 160km/h. When the traffic opens up again the cars in the fast lanes tend to do 160km/h plus and it is good if your bike can match and exceed that speed, unless you want to risk getting rear-ended. The actual speed limit is 120km/h, but unfortunately things have devolved to the point where the law is contemptibly irrelevant I'm afraid. But that is a topic for another time.
Can the 2013 S handle these requirements or should I go for the 2014 S?
