So I have about 500 miles on my 2015 FX and have been messing around with a windscreen and some basic riding techniques and drive modes. Before I put my windscreen on I was averaging about 75-85 wh/mi at an average of 40mph. Now with my windscreen installed and being tuned it I am getting around 60-70 wh/mi at the same average speeds. This is great as it shows what just a little aerodynamicals can do for efficiency! My problem is that I have no idea if this is a good number or not so great. I would like to see what other people's average watt hours per mile is (with average speed).
One thing I did not expect was that using the same MX style helmet that tried to rip my head off from the wind at 65mph was able to increase my efficiency with the new windscreen due to the visor acting as a second wind deflector! If I tuck a few inches wearing this MX helmet I lose almost all wind noise and my efficiency change to 55 wh/mi. Using a standard round helmet I can only get about 70 wh/mi! Again though, I have no idea if these are good numbers or not....any input is good input. 8)

Those numbers seem pretty good. I assume the energy is as reported by the dash (likely Wh going into the motor controller), not AC energy consumed to recharge. Important to make sure everyone is talking about the same type of energy!

Yes this is driving not charging and I am getting the info from the dash.

I believe my lifetime average on my 2014 SR over 1,500 miles is 166wh/mi. I haven't taken a screenshot from the app recently and I didn't ride to work today so I can't get the exact number for you. My commute is almost entirely all highway and I'm usually going 70+ mph. Plus I didn't buy the SR to see how far I can travel on a kW. I bought it so I can do full throttle launches, while grinning like an idiot, pretty much every time I come to a stop. ;D
-
Mine is 88w per mile in a fx but I couldn't tell you average speed, but 1/4 was done on one wheel
And that was in a big controller bike
-
I'm just a bit over 100Wh/mi at 55mph on my SR with a windscreen. If I tuck it stays a smidge below 100.

My lifetime average (400 miles in) is 118 wh/mi on a 2015 SR. I do a 50 mile roundtrip commute at 70 mph give or take. I don't have a windscreen but I do try to tuck a little. I get about the same amount of miles per charge as reported by Zero at those speeds.
-
I am a bit amazed at the difference in efficiency so far. Obviously we can't compare apples to apples as my bike has a wind screen now and weighs over 100 lbs less than the other models and is geared lower but that is still a big difference. I guess using math and assuming 5000 Wh capacity (not 5700 bc that is MAX and not a real Wh rating) at 65 Wh/mi I should get up to 76 miles per charge. As I have been tweaking the bike I have been getting closer and closer to 60 Wh/mi without changing my average speeds. If I would quit trying to wheelie over ever bump in the road it would probably be even better.
-
I have almost 700 kms on my ODO now, so not a lot, but rode in several circumstances. The consumption depends a lot on the circumstances. We had a strong wind the last few days and riding at 110 km/h with crosswinds increases the consumption strongly.
I just returned from a city ride through Rotterdam in Custom mode with strongest regen and it consumed 34 Wh/km (54 Wh/m).
I see a big difference in consumption between the app and the dash.
-
Rode the SR to work today so I took a screen shot of my consumption. For clarification, I don't have a windscreen on mine yet and I don't typically tuck while riding.

Tater,
What was average speed to work? All highway?
-
My commute is 90% highway and my speed depends on how much of a hurry I am. Typically I'll be doing 65-75 mph on my ride to and from work. Rushed mornings, like today was, between 70-95 until I reach my exit. My commute is only 25 miles each way and I can charge at work so range is not an issue.
-
Dirt riding (slow) on my 2013 FX usually runs around 70 to 90 Wh/Mi depending on terrain unless it's soft sand then it will go over 100 Wh/Mi.

Ok, just did a test with my 2013 SR equivalent with topcase (no shields or plastics [see signature])
27.6 miles into work, it registered as 29 miles in the app (I have the high speed gearing) meaning I needed to multiply my indicated 137w/mile by about 1.048 and got 143.6 w/mile
This traveling about 10% city and 90% highway from 65-80 and no more. Didn't tuck for this test but I have found it does decrease the w/mile by about 10 or 15 in the past.
My average to date is 126w/mile but over winter I largely went 60-65. I have about 8900 miles on the bike now and 1022 whrs used
-
I decided to check what the dash said compared to what the app said and there is a large discrepancy. The app claims 162 wh/mi but my dash claims 134.5 wh/mi. Picture included for verification.

Updated screenshot from the app so it's a fair comparison. (http://images.tapatalk-cdn.com/15/05/08/4638148f21dca0e6d4c5150e8ae00574.jpg)

I have not been using the app much as of yet but that is interesting. It makes me wonder about a few things though. I stated that assuming 5kwh and 65wh/mi I should expect about 76 miles per charge. I however during driving home without charging at work making a round trip of 36 miles was at 33% charge. I am no math guy but I think that given that data I would have only made it to about 50-60 miles. Might need to do do some more research on this.
-
Tater that is when you look at total pack SOC left when you are done and manually divide in your miles traveled ;)
-
Assuming that the app is correct on the amount of total kWH used, then the math for the app checks out. I don't know how many kWH the dash believes I've used so I can't check the math for that. Honestly I'm not overly concerned with it, was just something I noticed and figured I would share the info.
-
My app claims 89 Wh/Mi on my 2013 DS 11.4, after 13.5k miles. I'm surprised it's that low, but traffic does drag a bit around here.
-
I'm just a bit over 100Wh/mi at 55mph on my SR with a windscreen. If I tuck it stays a smidge below 100.
A little over, like 110, 120?

Hi folks, despite recently buying a Honda NC750S DCT and putting my electric motorcycle ambitions on hold for a few years, I obviously can't help keeping an eye on this forum and thought I'd pitch in here.
I am getting approx. 60 mpg at 70 mph. With 1 Imperial gallon being the equivalent of 44.11 kWh it means I'm using 670 Wh of energy per mile, measured, as you are, at the point of being fed to the motor.
In rough terms, your Zeros are 6 times more efficient in pure energy usage. If you then consider the 6 kWh of electricity used to refine that gallon of petrol, you could probably ride your Zero for another 60 miles, maybe even at 70 mph or close to it.
Lots of reasons to be happy about the efficiency of your bikes I'd say!
-
I took my bike off road over the weekend and had a blast. My only prep for the bike was to remove the mirrors and my windscreen. I have yet to put the windscreen back on so I took the chance to compare my numbers and found driving the same route at the same speed I have gone from 50-60 Wh/mi to 65-75 Wh/mi with no windscreen! So yes the wind screen does help with efficiency by a reasonable amount. It makes sense really. Wind hitting your chest vs wind being deflected by a windshield makes a difference. I can't get the small windscreen to get the air over my helmet as of yet though.
-
This is what I am getting on my Zero S so far.

I show 96 wh/mi, but that makes no sense. I have a 14.2 kwh battery, so I should be able to go 142 miles if I consumed 100 wh/mile, right? But after ~2000 miles, I can say that going from 100% to 20-30% is about 70-80 miles of riding. That's ~142 wh/mi. So either a) the percent charge is only a fraction of the true charge (ie, zero percent charge is not zero, or 100% charge is not 14.2 Kwh), or b) the calculated wh/mi number is wrong. I guess there will be charger loss...
Actually, I charge my bike through a kill-o-watt meter, and going from 30% charge to 100% charge is usually only 6-7 kW hours of electricity usage . So... using this as the reference, the watt-hours/mile is roughly correct ( 70 miles/ 7 kw-hour/mi = 0.1 kw-hr/mi = 100).... but that would mean my battery pack (11.4 + 2.8 power pack) only has about 10kwh true capacity (zero charge to 100% charge). So who to trust? I guess the Kill-o-Watt meter is the true outside reference, everything on the bike is just the mfg. claimed energy usage. So that's about 2 cents per mile energy usage... hard to complain.
-
The 14.2 kWh battery has about a little more than 13 kWh of useful charge. Check the Zero app next time you recharge your bike.

My 14.2 S shows 13.22 kWh when fully charged on the Zero app. Also, I once ran the battery completely down to "0" %, after riding 140 miles at an average 40 mph (a guess, my speeds varied from 30 to 55 mph) and it took 15 hours to fully recharge. The Kill-A-Watt meter showed something like 17 kWh after the bike was fully charged and the batteries balanced. I might also add that when fully discharged, the packs showed around 160 mV difference and when fully charged they (still) show 2-3 mV difference.

Hi, I'm thinking about windshielding my FX as well, can you post several pictures of your setup so I'll have a chance to see how you've managed to get these great results?

Yes I can do that sometime this week. Because I have been riding off road a bit I have had the windscreen off for a few weeks with an additional 500 miles or so on the bike. What I can tell everyone from my experience is that as far as the watt hours per mile the wind screen makes a huge difference. Driving the bike exactly the same on the same roads at the same speeds for several weeks with and without a windscreen I have seen low averages of 49wh/mi for with a windscreen to 60wh/mi without a windscreen. I have seen my battery percentage range between 60% without a windscreen to 73% with one on a one way trip to work.

Just over a year on my '14SR; my daily commute is mostly freeway, 70-80MPH or splitting lanes at 35MPH depending on what time I switch from telecommuting mode and go in to the office...
-
I'm at 55Wh/km (89Wh/mile) on my 2013DS. Mostly city commuting with some weekend small roads/highway mix.
-
I have been mostly going for range on my 2013 FX with some spirited riding and a few 20 mile 80 mph runs.
My Present usage is right at 50 ( going between 49 and 51 ) for about 1500 miles. Lifetime is 63. Bike is set up
as a SuperMoto with street tires. and, 28 tooth front sprocket. Speedometer is calibrated and, corresponds with
mileage shown when using Waze, or, Google Maps.

Hi again,
Can you please share a picture of your wind shielding setup to... maybe mimic and reevaluate your data?

Some impressive figures here!
I have averaged about 157 Wh/mi on my 2015 SR. This is over about 4000 miles since the end of January. Mostly commuting with a small amount of errand running. My commute is 25 miles each way, about 20 of which is 65-80mph, 4 are suburban 30-45 mph, and 1 is stop and go downtown.
Oh, and today it left me stranded at work (again!) with a "Contactor Error". So annoyed.
mambo dog face to the banana patch. Grrr.

Hello.
It's been 700 km on my 2015 SR with power tank. I do a 120 km highway commuting plus 10 km in the city. The bike has an average of 70 Wh/km which means ~110 Wh/mile. My trip only has 100 m ramp and I am going at 100-105 kph or 63-65 mph. I usually arrives home with 131 km and around 25% of battery, so the remaining range is approximately 40 km.
If I go at 115-120 kph I get the 150 km range that the dealer says. If I use eco mode or custom with 75% regen and 0% torque at mentioned speeds of 100 kph I can easily reach 180 km of range.

Hey, steven_first, what kind of windscreen do you have?
I'd like to try improve my range at high speeds as well. My experience mounting a Luftmeister (BMW's Vetter Windjammer knockoff) on my 2011 Zero S was that I didn't get any improvement.

Keep in mind, that speed, tires and riding style are huge variables.
So are aerodynamics. Wind screen good. Boxy saddlebags bad.
Another variable is rider size and weight. Big riders with a lot of weight are going to be a significant load for a motorcycle. Cages are heavy and big driver does not increas the aerodynamic drag, so cages don't really notice passengers' spare tire.
