Just saw this one the zero site.

Tried searching here for opinions about it, but didn't find anything. Anyone have it? How does it impact range? Some pictures would be nice too. The small photo on the Zero site doesn't give you much of an idea of what it really looks like.
-
It is still new, but people have good experiences with other screens an gain some range using them.

There are no customer reports yet, and it does not match anything in MRA's range, so I imagine it's been designed well enough for its size to make airflow work well on the Zero specifically.
-
I have the touring screen :) Can't say whether it has an impact (positive or negative) on range as the dealer installed it before I picked up the bike, but I am pleased with the wind distribution with it. Do please note that it is quite big :) Attached is a picture alongside my Shadow :)
-
Nice! How is it attached? Just wondering if it can maybe be removed easily to test the Wh/mi with vs without it.

MRA windscreens for naked bikes all have struts that mount to the handlebars. You can loosen some bolts to remove it.

I've had the touring screen from Zero for my '16 SR for about a week now and it's such a huge improvement. Highway cruising at 70+ is quite comfortable now and my commute seems to use a bit less charge, it's about 12 miles with 5 on the highway. Was using ~10% each way and now its like 8%. My bike is still new so my riding style is aggressive with the custom profile maxed out.
-
I use the touring screen since 4 weeks . My commute consists of 18km at a speed of 90km/h and 2km at a speed of 50km/h . Before using the screen my consumption was 59Wh/km, now it is 53Wh/km . The wind pressure is greatly reduced , but the volume of the wind has not (essentially) become quieter.

Like so:

My experience with the touring screen is minimal, but early results are quite positive. I rode from my house to Richmond, VA in June and had to stop along the way for an hour's charge. In Richmond, the dealership installed the windscreen & the charge tank. I rode back via a slightly different route, but pulled 97.9 miles and still had 10% left. It's anecdata, but it backs up what others have said.

Is anyone with the touring screen taller than 6' and if so, what do you think? I'm 6'4" and currently have a cheap $50 screen that has a similar shape and size like the Zero touring screen, but I'm not quite happy with it. Mainly, it is not tall enough to shield me without ducking. It creates turbulence if at full height and when fairly upright/vertically mounted. So I use it at somewhat lower height than its max height and at a lower angle. It works well this way, directing the wind somewhere in the middle of my helmet, so turbulence is not bad, but now I can't really duck behind it - too close and too low. I can't mount an extension on that screen - too flimsy, I think. I might give the Zero screen a try, though I somehow doubt if will work much better for me, being that tall...
-
I'm 5'10" long and the Zero (MRA) touring screen creates a calm area between the screen and almost the top of my shoulders. You want the parabellum and modify it I think.
-
I think I want the Parabellum too. From several screens that I've used, I've determined they either have to be small, directing the air well below my helmet, leaving it exposed but without new turbulence, or big and directing it above my head, covering me fully and without turbulence. Those mid-size screens that go near my shoulders or helmet create too much buffeting, especially if they are closer to vertical.

Since my dealer has no screens to look at and compare, and all I had to go by was the little pictures on the Zero site. Other than the deflector, the touring screen didn't look much bigger/taller than the commuter screen. Is the deflector really the only difference or is the screen bigger?

I think the answer is yes, the touring screen is bigger. I have a commuter screen on my bike now and have a touring screen on order. I'll do some side by sides once I get it.

I'd like to see them overlayed. PLease post the pics when you can, it will come in handy to future zero owners.
-
Can someone measure from the top of the lens on the headlight to the top of the screen (with and without the extension in the up position). Also, how wide is it at the widest point? Thanks!
-
FYI I contacted zero for the dimensions of the screen and got the following response:
"The new Touring Screen (10--8058) is 17" x 17" with a bottom taper of 4". The spoiler is 12" x 3 1/2". It's smaller than your current screen but the air foil is supposed to push the air up and over you. It's also adjustable."
I'm currently using the screen from China (http://www.ebay.com/itm/231923751389 (http://www.ebay.com/itm/231923751389)) but since I'm 6'3" its not quite tall enough. Its still hard to compare them since one has the spoiler, also they are mounted differently so that could affect the height as well.
Could someone with the touring screen measure from the top of the spoiler to some fixed location? Maybe the headlight, or whatever makes sense?
-
The spoiler doesn't extend up so much as out and away to change angle of deflection, about 16+3/4" from the lowest edge of the touring screen FYI.
-
Thanks! I think I'll stick with the cheap screen that I have for now - doesn't look like the Zero touring screen will be big enough for me (it is an inch or two smaller than the screen I have now, which is too small already). The spoiler might make a difference though. Hopefully my local dealer will get one installed on their demo bikes for me to try. Otherwise, I might need to get something like 25" tall screen to get head protection and wider too for shoulder protection. Right now the bike is just not pleasant on the highway and unfortunately I have a few miles of that on my commute.

FWIW, the main thing about a spoiler is that it softens the boundary layer above and behind the shield. I may downgrade my spoiler for the Parabellum because I chose it for the Zero Commuter Screen where I needed more deflection, and now I just need a slight softening and want to see over the screen again.
-
I got this last night and quickly swapped out my commuter screen This morning I noticed reflections from the headlight, which the instructions stipulated to avoid. What have others done about this - shallower angle? I installed it fairly upright like I did with my commuter screen.
-
I played with angles tonight and came to the conclusion that some reflection is unavoidable. The best I could do was minimize it when I'm in my most frequent riding positions. I left the screen in a shallower angle than I set last night; I'll see how that works for airflow tomorrow. With the steep angle, it was obvious how effective the touring screen is compared to the commuter screen. With the commuter screen, the wind hit my head and arms with about the same force. With the touring screen, my head is in quiet air but my arms are still in turbulent air. I felt more relaxed. Too bad the touring screen didn't come out a few months sooner because I'm sure I would have bought it with my bike instead of the commuter screen.
-
I'm glad you are able to get it working for you, but I'm not sure why it's called a touring screen.
One suggestion is to buy and use longer MRA mounting stalks that attach around the handlebars themselves instead of the risers. This allows much more freedom to position any screen so that it doesn't catch a headlamp reflection, and can place it up higher where it can smoothly push air over your helmet.
E.g. http://www.twistedthrottle.com/mounting-kit-long-kit-for-mra-naked-bike-windscreens-for-suzuki-sv650 (http://www.twistedthrottle.com/mounting-kit-long-kit-for-mra-naked-bike-windscreens-for-suzuki-sv650) which lists compatible windscreens as well.
-
Disappointingly, my average Wh/mi for the week is up after just 1-1/2 days with the touring screen in place of my commuter screen. I hope it's only because I seem to go faster before I roll off the throttle because I no longer have wind on my helmet to cue me to my speed. I'll have to be more careful to make a valid comparison.

If it makes you feel any better, this happens to me even with the Parabellum windscreen I had and the dustbin fairing! With the dustbin, I just had (past tense since my commute just got pretty short) a very difficult time not riding around at 75-80mph at the same Wh/mile because I don't need any more efficiency daily than that to get to and from work!
I also deal with a lot of shifting winds, too, which makes reliable measurements difficult. So I wind up using my throttle lock and seeing what average speed it achieves over a long period.
-
Ultimately, the term "mechanical sympathy" is very useful for understanding how a Zero is different from regular bikes - there's no grunt or strain that is anything you can feel unless it's the belt. So, any drag reduction just makes the bike super-relaxed compared to before and you're compelled to make it work just as much as before.

Yeah, my seat of the pants feeling is that the bike is accelerating with less effort, as if I have a tail wind. So I might be killing any gain in efficiency with more speed before I catch myself.

Well, you can always use Eco mode or set Custom mode to a specific speed limit and just peg the throttle to see where the efficiency figures land.

Wanted to add to everyones observations with the touring screen. I just installed the screen a week ago on my 2017 DSR. I am 6'1" With the spoiler all the way up the wind on the highway goes above my helmet. I don't get as much on my chest. I did notice a lot more wind noise with the screen however especially with the spoiler up. With the spoiler down its quieter. My kWh used is down from 150 to 110 on the highway. Overall in the last week I have noticed I used 3-5% less battery on the highway and about 10% less on the back roads. I usually get home after work with 85 miles remaining for range and last week I was getting about 105.
Like others have noted. It does cut thru the air better especially at speed and you will tend to ride faster. I usually run it in Eco mode commuting and that is where my numbers are based. A few days last week I ran in custom on the highway with 30% torque max speed of 106 and 100% regen. Any speed above 50 and you notice its much nicer with the screen. I would love to try the longer mounts to push the screen out more to get it a little straighter and see if it will quiet the noise down.

I tried two angles on the touring screen; one where the stock bars were pushed forward until the rubber cap touched the mounting clamp and the other where there was about a 1/2" between the rubber cap and the mounting clamp. In both cases the bottom of the screen was nearly touching the headlamp housing. The first configuration left the screen as upright as possible with the supplied hardware and didn't appreciably increase noise over my commuter screen. The second configuration gave the screen more back-sweep but I couldn't leave the airfoil in the top three positions because of the noise.

Third option not mentioned is omit the rubber caps and have the touring screen all the way out.

I pushed mine as far forward as I could with the caps off. The wind noise was still really loud. I had to cut 3/4" off the bottom so I can angle it up more and not hit the plastic around the light. Finally a lot quieter. I also do not get the headlight reflection anymore. This is due to the turndown at the very front not there anymore. This is the area that reflected the light onto the screen.

Best tip of the year, thanks!!!
Was on the verge of buying a larger screen, but is not necessary anymore ;-)
Cut 10mm of my windscreen.
Big different already.
Try this a while and maybe cut off even more.

So great to hear it worked for you also. I cut about 10mm off the first trial but decided on more. I used a cut off disk for my dremel and then the sanding disk. Followed by the polishing disk. Worked real nice.
The turn down looks nice but definitely restricts the movement.
One more tip. I had a hard time getting the screws to get nice and tight on the ball adjusters. So i used some grease on the threads of the screws used to clamp the ball mounts. They tighten down much better. Reduces stress on the threads and they turn easier when tightening.
