Energica / Re: SS9 seat cover to prevent wet ass
« on: May 03, 2024, 07:06:10 PM »
They wrote me back and said they have something with about the same measurements.  They'll invoice me (so not through the website) and I can buy it.  If I have any issues with the fitment, they'll take it back and give me a full refund.

I just submitted the measurements to Wind Rider for the SS9. Fingers crossed they have something for another bike that will fit it. I've seen that Goldwing riders are still waiting for them to make a seat cover that fits, so I'm not very hopeful that they'll make custom sizes specifically for Energicas any time soon.

Energica / SS9 seat cover to prevent wet ass
« on: April 25, 2024, 06:17:53 PM »
Any recommendations?  The heavy rains in California combined with the seat stitching and and frequent use and parking outside has led to the foam getting saturated and giving me a wet butt whether it's raining or not.  I'm looking for something specific to the seat - not a full motorcycle cover and not a custom seat.  Something better than the Bink seat cover by DS Covers because it looks only a little better than wrapping a trash bag around the seat.

Now $4k to get it sold. I'd keep it, but don't have room for more than one bike. Looking for a good home.

Zero Motorcycles Forum | 2013+ / Re: Help interpreting logs
« on: May 06, 2023, 07:37:20 PM »
Thank you all for the replies.

Some additional detail.  This bike is located very far away from me.  I could not extract the logs myself, and these text files were given to me in response to my request.

  My apologies for the mix of units that I posted. The logs are in SI units (which I prefer)So I posted those where I read them or made simple calculations, but then wrote my requirements is the "bald eagles pre square rifle" ® because I was lazy.

This bike for sale has a relatively new 14.4 kWh battery on it and low use. As I said, I expect it should get a lot better performance than what the logs show unless they were drag racing or something with it (I could only average speed over time due to sample periods).

At steady riding and the warm weather indicated, it doesn't seem to be doing better than my 2016 SR ZF 13, which does fine in the summer, but can't keep up high speed at freezing temperatures. Again, I'd expect a new and larger battery to show more efficiently even in warmer weather.

Zero Motorcycles Forum | 2013+ / Help interpreting logs
« on: May 06, 2023, 12:06:04 AM »
Hi Zero enthusiasts,

  Is anyone willing to help me interpret these logs, or better yet, guide me to resources so I can do this independently and help others?  I'm looking at a used bike logs and trying to anticipate battery health and range expectations plus perhaps any other issues I'm overlooking completely.  Although the trips taken are short and lower speed, I'm extrapolating a 100%-00% range of 100-160 km at 60 kph.  This seems far below expect performance values, but it could easily be that I'm not looking at this right.  I have some experience with looking at MBB logs, mostly for errors, but limited experience is evaluating MBB logs. 

  My real concern is being able to comfortably make a one-way commute at 45 miles and 70 mph in all weather, with the option to charge at work.  Bike is a 2nd gen Zero SR.

I would greatly appreciate anyone's opinion on the health of this bike, or again some pointers on education so I can do this myself.

Thank you,

Zero Motorcycles Forum | 2013+ / Re: Strange SoC behaviour 2017 DS
« on: April 22, 2023, 07:14:00 AM »
I've experienced similar to you.  You can click my name and look at some of the threads I started for more info.

My battery is definitely impacted by cold weather. It's finally getting warm out and the bike ran like a champ today. I expect it to continue to do well until it gets cold again. My bike has 40k miles on it, including about 10k since the SOC wonkiness has showed up significantly last fall. Assuming you're in the northern hemisphere, did you store you bike over winter and just start riding or was it doing fine in colder times?

I hadn't looked at the charging until you mentioned it. I checked my logs and my charger cycles between 9 and 13 amps. I don't have a DeltaQ charger to compare. I'm curious, does using it resolve your issues the the SOC? 

Fellow Zero riders, my DS has strange behavior of which I am curious about your opinion.

Since a few weeks I notice that the SoC is acting weird. Although the consumption on dislay (wh/km) is normal (avg ~50wh/km when driving smoothly on inner roads) the SoC runs down harder than before. For example, today I drove 107km and on my return only 18% SoC left. But when I key it back on after half an hour, the SoC is back to 31%. When I then connect the OBC, the SoC jumps to 45% within another 20/30 minutes. I'm used to an occasional percent or what increase, but not 27% in an hour of which only 20/30 minutes charging. 2 weeks back the exact same thing happened (with different weather conditions btw)

In addition, the charging process (in the app) also shows crazy things. Via the onboard charger (OBC) it charges with between 8A and 13A. That fluctuation doesn't seem normal to me. If I connect the QuiQ charger, it does charge constantly.

My conclusion is that the BMS is a bit confused by the fluctuating (and probably dying OBC, as is the case with many Zeros) and the battery is no longer 100% topped off. Cell balance at 100% SoC is 2mV, so that seems to be decent.

So from now on I'll just charge with the QuiQ chargers, but am curious about the opinions here....

The original SR with a 14.4 kWh pack claims a range of 90 miles at 70 MPH. The new SR with 15.6 kWh pack claims 84 miles at 70 MPH. I know the new platform is bigger/heavier - is that the full reason that the range claim has dropped while the capacity increased, or did Zero decide to be less optimistic? Is the battery chemistry the same between the two battery packs?  Anyone know if the cell voltage at 100% SOC on the 14.4 battery corresponds to 100% of the 15.6, "110%" of the 17.3 or something else?

What else am I missing for an apples to apples comparison of the battery and range?

Thank you.

Thanks for sharing that.  If you ride in cold weather, what's been your experience with how much that impacts range and performance?  It doesn't get too cold where I live - lows don't get more than a couple degrees below freezing.  I'm sure newer batteries do better than my 2016, but am curious how much so.


For what its worth.  If I am doing 70 MPH on my Ribelle, which I believe is the same power train  / battery pack as the SS9, I can easily get 100 miles on the battery.   Extra Urban, I never understood the wording either, just say you are on the gd highway already.  Yah at 70 plus MPH it eats range down.  Ive done way over 70 mph and squeezed 100 miles out of my battery.  When I am in stop and go traffic or more 'city ish' driving like 45 mph or so, I can get about 140 miles out of the battery.  I think the SS9 would do very well for what you need.

If you get a bike that barely makes your trip you will be cycling the battery almost 100% every day. What do you do when you lose 5% of capacity? Or when it is 40 degrees, and your range is reduced? You will have to charge at some point during the day. If you are trying to avoid that why not get a bike that can do 120% of the milage you need? That way you could do the 90 miles a day for many years before the range dropped to 90 miles. You might pay more now but the battery will last allot longer! An Energica SS9 would probably work. I test rode one recently and liked it. Maybe someone with an SS9+ can chime in

I don't plan to ride without charging at work, but would feel better knowing I wasn't dependent on it.

I was considering the SS9, but it's hard to get a straight answer about it's range.  Energica advertises 130 miles of "extra urban" riding, but doesn't say what that is. Just yesterday, someone posted in am Energica group that they get 70 miles at 70 mph with their 21.5 SS9. Even if that' estimate is on the low side, itt doesn't sound like that bike would give more cushion than one of the Zero options.

Do you have any possibility of being able to charge after the first half of your 90 mile round trip?   

Even a 14.4 kWh bike like my 2018 SR with charge tank will do close to that total 90 mile trip.   My wife and I have ridden 2-up 57 miles from our house to a destination and still had about 35% remaining.   To return home, we charged up to about 75% for 30 minutes using a public charger near the destination.   

Point being that a normal 14.4 DSR has a range of close to 80 miles @70 mph.    If you ride 45 miles to work, can plug in to even a 110v outlet for an hour or so, you would easily be able to get back home.   

I would much rather have level 2 charging on my bike as an option versus a power tank.

I have a 2018 S with PT and I would say that traveling 90 miles at a continuous 70 miles an hour would be pushing your luck. Recharging the battery would take 12-15 hours at 120V. If you could stay around an actual 60 mph, that would work, but once the SOC gets down to around 25%, the performance is going to be degraded somewhat.

I pretty much have to charge at work right now, though I do it unofficially.  On the worst of days (cold, wet, headwind), I have to go significantly under the speed limit.  On warm days, I can make it one way easily while going with the flow of traffic.  My employer hasn't committed to an EV charging plan.  Demand for charging far outstrips supply, so it's a free-for-all now.  If all the charging stations are full for a day or I lose the ability to charge at work altogether, I'd like to be able to have the option to go slower like Richard mentioned, and not risk getting stuck.

One thing to note is the extra 10% on an SR is by overcharging the battery (just beyond what Zero chooses to charge it to by default, not over what it's actually specified for) and you have to choose it on the dash every time you put it on charge. Forget to do so and you don't get it, and people have also reported that the last little bit of charging can take a very long time. You're still "only" going to have 15.3kW/h of capacity, versus around 18kW/h with a DSR and PT. Even adding a PT to your 13kW/h SR would up it to 16.6kW/h, any reason why you haven't considered that? Also it would be a bit more hassle but you could even upgrade yours to 14.4kW/h and then add the PT and it would still work out a lot cheaper an option, especially if you sold the old pack.

I've read that it's not recommended to mix old and new batteries.  The battery I have is getting old and tired for doing extended highway runs and will just get older and 'tireder'.  I don't feel like spending $3k on a power tank would give me that much life extension.  I'm not sure the cost of a 14.4 kW/h pack and PT plus install, but I'm guessing around $12k?  That's definitely cheaper than $21k.  Also cheaper for crazy CA tax and insurance.  I haven't paid too much attention to longer term maintenance costs, but have read about wheel bearings and forks going bad.  Do you know anything about other long term costs?  It's something to think about, but would want to get more informed about potential costs of other things failing.

These two are very close in price and claimed range according to specs.  I don't really care about the bells and whistles; I just want to do 90 miles round trip commute at 70 MPH.   

Is the battery chemistry different/better for the "new" SR that I could expect it to perform better in the long run?
I had a hard time finding the range spec for the DSR+PT, but I think it's claimed 97 vs SR+Cyber Store of 93 miles?  Since these are both from Zero, are they both equally accurate or optimistic?
I haven't ridden a power tank model.  I know it will feel more top heavy, but don't think I'll notice much going in a straight line.

I don't like that Zero killed the original SR and prefer that over the DSR. I've read that the Gen 3 bikes are more susceptible to water intrusion than Gen 2.  Are there any other reasons that I'm missing that would swing towards a DSR+PT?

Thank you.
