How different was the airflow/buffeting after the heat gun treatment?

Between forming it, and angling the screen, the buffeting is no issue. The wind noise is nominal, and mostly caused by the modular helmet I use.

I agree @Hammer_und_Strom it is gawd aful ugly. But thus far it's the best option I've tried. Lucky for me, I have a spare CalSci screen that cracked. I've actually taken the jigsaw to it to make the top half more tapered on the top corners so it looks more like a windscreen and less like a pane window. I'm hoping to mount it tonight and give it a rip to see how the aerodynamics change with the slimmer profile.

I'm 6' 2" (188 cm) with long back, 34" inseam. I've now tried followind screens on my V-Strom 800 DE, with standard height saddle.

Standard 800 DE screen, mounted on lovest or middle holes, is useful. Does not provide almost any wind protection at all, helmet visor is covered by flies just after 50 kms ride. However, for a long rider it allows quite free airflow to helmet, without notable turbulence. Useful screen for off road riding and for hot weather. I also tried PUIG screen extension and MRA Vario adjustable spoiler on the screen, but both cause quite bad turbulence on helmet.

Standard 800 RE touring screen. Provides much more wind protection for the upper body, since it's wider and taller than DE screen. When mounted in the lowest holes does not cause so bad turbulence on helmet for the rider of my height. It is somewhat usable, but the downsize is that it blows most of the airflow direct on my neck, which feels a bit uncomfortable on highway speed. I also tried Puig screen extension and MRA Vario adjustable spoiler on the screen, but both cause quite bad turbulence on helmet.

Puig Touring screen. Wide and quite tall. Gives good wind protection on body, but causes quite bad turbulence on helmet. I also tried PUIG screen extension and MRA Vario adjustable spoiler on the screen. Puig extension does not help, but MRA Vario spoiler helps a bit against the turbulence. Puig Screen can also be bougth with adjustable Puig spoiler (just like the MRA spoiler I tried). I quess it could be quite good touring screen for shorter riders, up to 180 cm tall, offering good wind protection for upper body and not causing so bad turbulence on helmet (for shorter riders).

Tallest National Cycle VStream. VStreams have been great on my previous bikes, R1250GS and CRF1000L, but surpricingly it does not work on V-Strom 800. It's not so wide than Puig Touring or 800 RE screens, so it does not protect upper body so good. Without spoiler causes quite bad turbulence on helmet. Screen is good quality and very expensive here in Finland, and was therefore a huge dissappointment. I also tried PUIG screen extension and MRA Vario adjustable spoiler on the screen, but neither helped so much. Finally I placed about 5 mm spacers under the lower mounting points, also adjusted the screen to the lower angle, which also let a bit more air behind the screen. That helped and with the MRA Vario adjustable spoiler is the best touring screen solution for the rider of my height, from the four options I tried. It's far away from perfect, but is tolerable and the best of the options I tried.

I'll keep the standar DE screen for the off road and hot weather use, RE screen for the cold weather use on local rides and VStream with MRA spoiler for long tours. Its not perfet, but it's least bad. I would still like to try Givi Airflow, but wouldn't like to buy it, since I've allready spent about 500 EUR for screens and spoilers.

For the feel, finnish and quality, both OEM Suzuki screens and VStream are equally good, Puig screen is clearly cheaper made.

I’ve found the same to be true with the buffeting and the Puig extension on the OEM touring screen. I went back to the original small screen for less buzz on my helmet. I never was bounced around but my helmet screen would vibrate.

I have an update on my experience with the Givi Airflow and the CalSci Large on the 800 Touring.

I first installed the Givi with an additional puig deflector on top, and in the lowest position it was suitable for all speeds except 80mph plus.

Out of curiosity I order an installed the large CalSci windscreen. It definitely provided even more protection, but after a week of doing 85mph for 42 miles each way, the screen cracked.

Obviously I was not pleased. I reinstalled the Givi and I'm sticking with it.

Edit: Also, my fuel economy noticeably deteriorated with the CalSci. It's extremely good at blocking wind, but does so with all the finesse of a large brick wall being pushed along.

I installed a Givi Airflow. Even with the front screen at it's lowest position it was too high for me (5'9", 31" inseam). I cut about 1.5" off the front screen. It's perfect for me now in it's lowest position and there's lots of up adjustment if needed for some reason. The Airflow is a keeper for me. Little to no turbulence. Some wind noise but my earplugs take care of that.

Curious - did you call CalSci about the crack? I would think it would be warrantied, unless something smashed into it or the screws were overtightened when it was installed.

CalSci offers free replacement if it’s within a certain short warranty period - maybe 3 months.

Yesterday was nice, calm day so I made a little bit more testing. I now have the tallest VStream screen on, with MRA Vario spoiler on it. It helped a little for buffeting when I put about 10 mm spacers under the lower mounting points.

However, I noticed that most of the turbulence and buffeting to the helmet come beside the dash fairing, under the screen. I think National Cycle has failed miserably on the design of their screens. Screen should be wider and longer on the lower end, just like Suzuki RE touring screen and Puig touring screen. Dash/headlight fairing is so narrow and does not prevent turbulence heading straight to the helmet. Even if the VStream screen is so big, it actually does not give so much protection against the airflow, since there comes so much airflow and turbulence straight to the upper arms and body under the screen, beside the dash fairing.

Even if the VStream + MRA Vario spoiler combination is the best I've found so far, I'm not happy yet. I'm suffering quite bad tinnitus, so for longer tours I would like to find better solution, with less turbulence and more silent. For local rides and off roading the standard DE screen is good enough, allthough it does not give any weather protection at all, also not so good for long touring.

Has anyone tried Powerbronze wind deflectors or their Chines copy? I consider making my own.... price incl. fraight from England, duty and VAT is ridiculously high. Chinese copies are not for me.

There are now also two types of rally fairings available for V-Strom 800.

They are not touring screens, but could give turbulence free airflow on helmet, just like DE standard screen gives for tall riders.

I’ve developed tinnitus as well. It’s driving me crazy. The wind turbulence sucks the joy out of taking long rides. I’m leaving for Maine next week and I’m desperately trying to find a solution.

 

[Due51]

I came across this article which includes test results and graphs. Surprisingly, the best result for wind noise for people riding in the upright position (helmet at 90 degrees) is no windscreen following by a straight screen that's 15cm (5.9") above your ears.

I haven't contacted them yet. I tightened the screws in an x-pattern using very slight pressure, no more than wrist-snug.

Nothing hit the windscreen either.

I actually installed aliexpress copies of the powerbronze deflectors. I actually had little issue with buffeting from the sides of the dash, but after I installed Adventuretech foglights it became unbearable. The deflectors solved that problem.

Mine cracked because there’s so much surface area that it can only take so much wind before something gives.

That's likely what happened: I commute 42 miles each way, 99% of it at freeway speeds.

I just now noticed, that Suzuki offers two different tall screens available for 800 DE.

Part #94600-25820 is 80 mm taller than DE standard screen. It looks like same than RE standard screen. On Suzuki site it says, that it only goes for 800 DE and 800 RE owners are told to get #94600-25850 instead, that is 38 mm taller than RE standard screen.

Mine is the lower of them two, but I don't believe the higher would work any better.

 

[Due51]

I have the 25820 for my 23 DE.
I'd be interested in the 25850 if it's taller than the 25820, and fits the 23 DE.

 

[NVDucati]

Does anyone also have a DL1000 / 1050 2014+ to see if the four mounting bolts use the same pattern?
That would open up a huge selection of windscreens.

 

[Due51]

I called Suzuki customer service in California and they couldn't tell me the size of the 25850 nor the reason why it wouldn't mount up to the 2023 DE other than "that's what it says" lol

 

[Due51]

I may have stumbled onto the most unlikely solution to my wind and buffeting problem lol

In this upright position, the mirrors deflect the wind coming around the screen. It smooths everything out. It looks ridiculous but if does the job, I don’t care.

 

[-mek-]

I made my own side deflectors. I used to have BMW R1250GS and knew it well. I ordered a BMW part #46638556639. GS dash is about 50 mm wider than V-Strom dash, so I cut the BMW deflector in three pieces. And it works. It reduces the wind pressure coming beside the dash to my stomach. Not all, but much less now. And it does not look so bad either.
