Cheap solution for buffeting effects, really works.
I installed the MRA Vario today along with some other goodies. Took the bike for a spin and was very impressed with the reduction in wind noise and buffeting. I was really bothered by the noise with the stock screen, it absolutely did not work for me. I'm glad to report that I'm now a happy camper.
The only problem I've found is that the screen interferes with the bars at full lock. I have the bars tilted forward from the stock position to aid with standing.
I found that adding spacers under the bottom of the tall Honda Touring screen (allowing a 2" gap at the bottom) helps reduce buffeting greatly. I ride with my face-shield open a couple inches . . . I now have a smooth airflow over my helmet. 5' 11", seat in the high position. It lowers the top of the windscreen for full view over the screen.
Looks like the V-stream screens have been released; I'm hesitant to try one out until I hear reviews though.
Think Madstad should build a unit for the AT soon. Tilt function far exceeds height for buffeting problems.
I love the Vstream on my S10, but man the Vstreams for the AT are butt ugly!
I really like this approach. What did you use for the spacers?
I had extra elastomers from a PHDS (stacked 2 each side taped together). You could probably make spacers from a heavy rubber hose. I used neoprene rubber faucet spacers on the middle mount (stacked as needed).

Anyone try the Madstad screen yet ?
Trying to decide between mra vario , balzen brackets/stock screen , or the madstad offering.
6'3" tall with a shoei multitec helmet. Will be installing the seat concepts rally seat before spring which will raise my noggin a little higher.

Update: I've now got almost 10,000 miles on my Africa Twin, including a 4000-mile trip through Labrador and Newfoundland, and thoughts of replacing the windscreen have disappeared. The cut-down one (see post #17) has worked out great for me.

just picked up an AT. second ride and I determined the WS was creating some buffeting and lots of low frequency resonance. I too am the guy always riding with a short windscreen. Get me in clean quiet air and stop jacking around with all this. So it seems the 345mm tall Powerbronze sport is the shortest? I like it. But think something around 320 is best. any others?
the fit and finish is quite nice. i do need my risers now though, my cycras and gps clamp bump it at full lock.
Please keep us updated on your progress.
Thanks in advance.
Even the low powerbronze leaves some noise. Running screenless is the most quiet. But it sort of defeats the purpose of an adventurebike. I recommend that you invest in the mra vario straight away. I tried a lot of different solutions myself but did not get happy in the longer run. If the vario turns out to be too hot on the warmest days I will probably ride screenless. I will try and just loosen the screws and push the screen down (or was it up?) to get it off without loosing or damaging the rubbernuts. Make sure to buy a pack of reserve nuts anyway.
A tacky tip for reducing noise: Suck on your foamy earplugs to wet them before inserting. (But after shaping them a bit with your fingers.) Test for tighness by rubbing your fingertips fast against each other close to the ear. My finding is that whenever the plug works poorly it's because the tip was bent due to too much friction on insertation. Putting them in your mouth is tacky but nobody stops you from washing them as often as you want to. (They need some time to dry and will be very big and fluffy until the water is out.) Carrying several pairs is a good idea since unsuccessful insertation leaves a plug deformed for some time and it's better to just try a fresh one. I lost my own inhibitions after seeing a famous mc journalist suck on his.
Just received the Batzen screen mounts. Nicely made. Sprung for model with the gps mount, that's going to do nicely for one of my units, the other I'll mount to the bar.
I'll follow up when tested.
And with pics of your mounts

I have a madstad on now and I love it. Problem is solved. I tried the MRA Vario touring screen, the touratech screen, and every wind deflector I could find. None of them worked. I wear an adv helmet with a "beak" on it. I also tried sealing out air around the fork tubes and fairing. That did not work either.
