Zero SRSuperbike
Hello everybody
My wife has a zero 2013 s ,so did i.We use them also in winter,so it is nice to have some protection against wind and rain.We had both a three bricks battery thus limited range.There were no full fairings on the market so i decided to make them myself.It had to be aerodynamic, comfortable and beautiful.
Later i bought my 2017 sr and made again a fairing.This one has another top since everything around the handlebar is differend on the post 2013 models.I had the idea of bringing the mirrors inside the fairing.After two prototypes i found the right place to install them.They give a good view except when riding with a passenger.
I tested it on the highway in eco at 113 km/h twice.
First time at 12°C ,i had a range of 155 km
Second time at 25°C i had a range of 180 km
This was even better than i expected.
-
Wow, those fairings look really good and integrate with the tank. I'm impressed!
US unit conversions:
96 miles in 54F weather
112 miles in 77F weather
Those are really good figures for 3-brick batteries! 8-9kWh suggests 80Wh/mi?
Please see if you can provide a better pack estimate for the efficiency calculation, and let us know how fast you were going.
-
Those figures are not from the 2013 s but from the 2017 sr (the red one)
-
Aha. So, taking the 13.0Kwh max-rated battery for 2017 as 11.4kWh nominal:
119Wh/mi in 54F weather
101Wh/mi in 77F weather
Those are good figures and represent a solid performance at highway speeds. Do you have a set speed or speed range you covered that distance within? Just trying to compare it to mixed riding or entirely-70mph (113kph) runs.
-
Those look awesome, nice work. I particular like how you reused the stock headlight and extended the sides out so it would shield the legs, looks like it would be a nice place to put some chargers too. I take it the windshield is fixed to the handlebars and turns as you steer? Interesting design and certainly not the easy route, any particular reason you did it that way?
-
I've cross-posted this over to the FB owners' group: https://www.facebook.com/groups/zmcowners/permalink/2968162839919571/
I also like the flaring of the fairing. Is any air taken in front around the front battery plate? That might help with cooling and some drag relief around the inherently flat front.
-
I want - nay, I NEED these fairings.
I'm throwing money at the monitor but still no fairings :(
Seriously, I want my Black Forest to get a decent range when riding faster than 90 km/h. How do I get my paws on these?
They look at least as good as the SR/S, if not better.
-
I did highway in two directions and looked at 50% soc how many km i had left.
The top turns with the handlebar so there is no big gap to turn the handlebar in,pure aerodynamical reason.
The air that goes passed the front wheel goes up to decrease the underpresser behind the winschield ,and a part of it comes out between my knees and the battery for the same reason. There is a plate that covers the front of the battery witch goes up to the front leggs,it keeps out dirt and water,but there is no coolingair to the battery

The Vetter nosecone/turret design is similar in this respect and really rare among fairing designs, but I like how it works and looks. The Hollywood Electrics fairing (HE) uses setback risers for the handlebars to clear the upper fairing at full swing instead.

Those sound like reasonable choices. Is the updraft through the center of the fairing behind the windscreen weak or strong?
One reason the battery often requires less air behind fairings is because of the reduction in power demand at speed. If you can arrange it, try to test how battery temperature rises at high speeds in hot weather.
Do you have previous experience in fairing design or aerodynamics, or is this your first design?
-
Holy cow, that's so well done!!
-
The updraft behind the windscreen is rather weak,if you don t hold your hand above it you don t notice it.The air intake behind the wheel is very narrow, just 3 cm wider than the front leggs.
I made fairings for my moto guzzi 30 jears ago (yes i m old) and i learned about aerodynamics when i was aircraft engineer.
These fairings fit only on zero s / sr ,sorry MyNamesTaken
-
Well done, then! Updraft should be not so strong that raindrops travel with the air through the fairing (obviously the rider doesn't like to get wet, but also the moisture collection can wear on the equipment).
The integration against the tank looks so seamless that I did not notice it from the side and thought you had fabricated a new tank.
The mirror placement looks "under arm" which might vary per rider. An owner could use bar end mirrors (like I did with the HE fairing) and use those spaces for paneling (12V power or phone mount).
Like the HE fairing, I suspect this might still work with DS/DSR bikes if the owner: (1) removes the DS high front fender and adapts the S low front fender, and (2) either swaps the handlebar or uses setback risers.
-
It actually is a new tank, and it can hold 18 liter. Everything inside stays dry even in heavy rain.
Speaking of heavy rain, have you noticed the rear wheel hugger?
-
Wow. This keeps getting more impressive. Yes, that rear wheel hugger looks quite good.
Okay, so what we all are dying to know is can you produce these? I can't imagine it can be done terribly cheaply, but maybe you have enough plastic fabrication knowhow and access to make this feasible.
-
Awsome work!!!! I sure want one exactly like that. 8) I also have a SR2017 fully quiped but no fairing :-\
I know many in the fast shared their plans or even offered to sell the material or parts to make tghese like the famous Aprila RS125 that was fabulous!
Gain, even if you offer some plans or instructions to help us to ralise a project like yours, it would be apprecaited!

-
Looks freaking great! Any chance you can do some actual Wh/mile testing and freeway speed?
Thanks!
-
I remember seeing that rear hugger on one of the FB posts, dont remember who posted though! But i would love to get that. It certainly looks to make the airflow a bit cleaner on the rear. But man those front fairings are really well made!
I really ran out of luck trying to find a LS front fender that would fit the S platform :'(
Did you replace the rearview mirrors with 2 phone screens (and 2 cameras)?!!
-
That is awesome! Love how you make it look like factory with the way the tank flow seamlessly into the fairing.
After over a year, my fairing is still a work in progress, as I can't decide how I'm going to join it to the tank. Fortunately it is still functional, as I'm getting about a 15-20% range increase on my 17 S 13.0.

I sold wheel huggers here in europe already for 250€ .
A whole fairing is so much more work .I will have to make another one to have an idea of how many hours it takes. What about the painting ? If you want it in the original zero colour i ll need a sample like the front fender or the top of the tail or so. If it needs to be in two colours like mine, that triples the work.
If it has to be shipped to another part of the world how many papers and stamps would i need and wat would it cost?
I ll have to ask around and think about it.

Okay, it sounds like the same issues that Hollywood Electrics faced when pricing its fairing. Thanks for considering the idea, at least.
Hollywood Electrics does have a bracket set for pushing the headlamp and dash forward, and setting up a larger space between the headlamp and head tube for the electrical routing. Does your design have such a solution or need one?
-
In my design the headlight is held by the fairing itself and the dash sits on two small brackets that also hold the top of the fairing.
The whole fairing gives only 200 gr extra weight compaired to the original bike.
It fits like a glove on the zero s /sr but it doesn t fit on a ds unless you replace the handlebar and the front wheel and remove the front fender. Anyway the ds is not made for highway use .
-
I've ridden the DSR 620 miles in a single day via highway, so I disagree about what it's made for. I find it much more manageable at speed than the S/SR just because of the geometry and front wheel.
I'm sure an interested DS/DSR owner will make do with what you've described. Given the presumed expense and benefit of the fairing, the remaining accommodations are relatively minor.
-
Doesn't the DS also have a differently shaped tank? So, with how that fairing integrates with the tank it might not match up with a DS.
-
What i mean is that they didn t give it a longer suspension ,crosstyres ,a big mudguard and a big front wheel to adapt it to hihgway use. I read it was to ride it on rough country roads.
Of course you can ride it on the highway ,but it is made for dirtroads aswell.
So if you do mainly highways you r better off with an s ,pure technicaly .But if you like the ds more, why not? It s a free choise and the more choise there is the better.

So is the exterior of the tank also new? I assumed you just made a larger external tub to get the larger volume.

I made the first fairing in2015 on my 2013 s and it had that handbag with a zipper build in the tank,so i made a complete tank witch looks like the original but it is less wide where it joints to the front parts of the fairing. Those points on the front of the original tank where mutch to wide. It is still the same model on this fairing. Except the top and the colour, everything is the same as 5 jears ago.

It is made of glassfiber and polyesterresin. It can also be made of carbonfiber with epoxi One has to have some kwowledge of the technique to have a good result ,even if he would have the moulds.
It takes a lot of work to create a new shape and make a mould. Ones you have the moulds it is handwork to make new copys ,and it takes a lot of time. I don t have plans wich are detailed enough to be of any use. I just made some sketches and then tryed with cardboard and tape to make in 3D what i had in mind. Than i made a first rough version in thin and soft aluminum sheet,wich i used as a mould for the first glassfiber version. It took weeks of work with sandpaper and polyesterpaste before it was the way i wanted it.
The complete fairing consists of 7 parts +the windschield,they all have to be created like that.
That is how i did it ,some shape it in wax or plaster but in the case of a fairing it is difficult to make it fit around the bike since it s impossible to make these materials thin enough.
Maybe i can send fairings to people in the future,i found some one to help me make them, but it takes about a week to make one conpleet fairing .
-
Those are just mirrors low tech.
-
Agh, the quoted quotes are hard to read.
-Crissa
-
I made a new fairing and painted it the same as mine.
Now I know it costs 1504 € + 500 € to paint it in two colours ( one colour would cost 300 € )
This is without taxes and transport from Belgium.
So if someone is still interrested ,let me know.
-
Do you also plan to make a streamlined front fender? (Say like the LSR fender). That would be perfect and i would certainly be interested in that!!
-
i have plans for a front fender and also for a aerodynamic topcase but the problem is that i have more plans than time.
i have been asked to make a rearwheel hugger for the srf /srs too.
-
For such a one-off arrangement, that’s a good price. I’d be tempted but I’m already invested in a sport fairing and now a streamlined dustbin mount and tail.
I would really like to see someone adopt this and report how it works for them. I’ll contact some people who tour with their Zeros to see whether I can convince them.
-
these are four big advantages to convince people
it protects much better than a windscreen (only the helmet and the hands catch wind)
it has a tankcapacity of 17 liter (thats as much as a standard sidecase)
it gives a better highwayrange than a powertank
last but not least, it s a headturner
-
This fairing is nothing short of spectacular for the Zero! I'll keep a very keen eye on this thread and i'll bump it back up when i'm doing more highway trips/tours on my Zero and thats when this will come the most in handy! But seriously *bows down*

hans2183 made a great video this weekend of us and our bikes.
Thanks hans
