    I also ordered the new handscrews to easily adjust the screen:
    [​IMG]
    My previous screen is the MRA screen (in Santa Cruz called the 2 piece Wunderlich screen). Compared to the MRA it is wider and because the screenmounting thingies are set up differently the screen sits a bit lower but can be raised a lot steeper. With the MRA screen there was still a lot of riding wind hitting my upper arms, pulling them back. I do not notice this anymore with the Wunderlich screen. With the MRA screen the pull would only get worse from steep to low angle setting, with the Wunderlich screen there doesn't seem to be a difference in "arm pulling" factor with these angles. My priority was to decrease this "gorrila arm" effect when riding at high speed (150km/h +) on the Autobahn (elsewhere I always ride the legal limit of course :evil ). The Wuderlich screen does a good job at eliminating that effect, more than the MRA. Noise seems the same compared to the MRA, but I must add that it's always windy in Holland and I always wear earplugs. Compared to stock it's certainly better. When riding the Wunderlich in the lowest setting the airflow is pretty clean, although at my 6'3" / 1.90 meter (34" inseam) it blasts straight in my face. This blast, although clean, is noiser than the tiny bit of turbulent air that hits the side of my helmet when riding the Wunderlich in the steepest setting. Because the screen can be set steeper than the MRA the airflow is just a bit higher. The MRA screen in the lowest setting (angle, slide didn't make any difference for me) made my helmet lift up and created a lot of "gorrila arms effect", the Wunderlich doesn't have this. I think I'll be using the Wunderlich at low angle in the summer on the backroads and the steep angle on the long freeway drones, but I still have to experiment.

    Concluding, so far I'm very satisfied with this new screen. I like it better than the MRA. The bigger width makes the long, high speed freeway runs more comfortable, the mounting setup creates optional settings from "Adventure screen, clean blast in face" up to "Goldwinnabago, fazer torpedo shields up".:smile6 .
    I think this is the nicest looking and best working alternative for that ugly Aeroflow.

    I now have a stock screen, MDI screen, MRA screen and the Wunderlich screen. I have no riding experience with the Givi or Adventure screen.

    The sturdieness is similar to the stock screen. Because it is shaped and curved it can't really flex. The MRA is straight, which makes it flex a bit in strong wind. Still, I found the MRA very decent and sturdy. No wobble at speed, hard to imagine seeing that bullet proof adventure screen do that. The Wunderlich screen is a bit thinner compared to the Adv. screen, but there is no wobbling at any angle, at any speed.
    Could well be.... I'd have to switch back to the stock screen just for fun, the last time I rode with the stock was almost a year ago... but I'm too lazy to switch those mounting things back and forth :nah

    Man, I purchased my Wunderlich tall touring a week ago, and now I'm Jones'n big time while waiting for Fed Ex ground. I can't wait to see how much reduced the buffeting is on my XXXL helmet (aka melon head). If buffeting while "slab" speeding improves as much as I hope, and given the death stats on slab riding could make a slab convert out of me. Currently, I avoid the slab like the plague.

    Fed Ex ground better get here today or I'll have to call BMWscruz.com and ask what the hold up is.

    I guess you're talking about the MRA (2 piece) screen, right ? I don't see the new Wunderlich (1 piece, wide, tall) screen available on the scruz site... You're currently using the stock screen ?

    The scruz site doesn't show the Wunderlich tall touring, but they sell it, and had it in stock (supposedly) when I called. Yes... My name is Patrick, and I used the stock screen for 21K miles. Soon, I'll be getting most of these congo playing monkeys off my helmet, and try to look at the slab with something other then dread.

    Bummer, scruz sells what they call the Wunderlich tall touring, but it's last years Wunderlich tall touring, so it's really a smoked tinted Ermax. So, I have to send it back today and order my Wunderlich tall touring from Germany.

    Hey Flying Dutchman or anyone else who can answer :)

    How much higher and wider than standard is the Wunderlich 1 piece screen...

    I am still not decided between the MRA which sounds good for airflow but doesn't seem much wider than standard and this new Wunderlich screen... I don't have enough money just to buy both and see what works - cos in Europe they won't take it back if you don't like it... :(

    Flying Dutchman - any chance of a photo of the original screen superimposed or sitting behind the new Wunderlich?

    Thanks all

    Just a few quick pics before I rush off to work...
    I'm holding my stock screen in the same mount-angle as the wunderlich in the highest setting (sorry, I tilted it a bit... I'm in a hurry...):

    JimO, you've done an amazing job with this! It's awesome. I put a link to it at the top of The Hall of Wisdom. I'm also happy to host it on ADVrider's server, but it looks to me like a very dynamic document in need of reasonably frequent updates. You wouldn't be able to edit it on my server.

    You might send me email or a private message and we can explore the options.

    For the most part, I'm liking my GS, but the stock windscreen SUCKS! Any speed over about 60mph feels like a mule kicking me in the helmet. The only thing that helped is if I removed the rear screws and laid the screen down. This, of course, produced an enormous amount of windblast to my body.

    So...last night I grabbed the old cordless jigsaw and cut the flip off the stocker. I put the belt sander to it to smooth out the rough spots, and polished it off with a little 220 grit. It looks pretty nice. The buffetting is down, but not gone, and windblast is kept at bay.

    I went by a fellow GS riders house, and showed him my screen. He let me borrow his Givi. I've read that for folks my height (i'm 6'5"), that the Givi isn't very effective. Actually, for me it worked alright. Buffetting was still there, but only at super legal speeds around 90mph. I did notice that the Givi screen actually rubs the plastic above the gages a slight bit. Of course, that's nothing that jigsaw can't handle.

    So, now I'm wondering if I should get the MRA/Wunderluch two piece screen, or give the Givi a shot? Anyone have both and can give an accessment.

    Being a former RT owner, I really got used to that adjustable screen. Now I have to set it and ride. What's the best choice?

    I've put about 6 thousand miles on the Givi and now, just about 1000 on the MRA. I like the MRA better. I don't think the MRA wobbles any more than anything else. Fully extended, the MRA is about as tall as the Givi, but I couldn't adjust the Givi low enough (without a drill) to get clean air to my helmet. With the MRA, I can put it all the way down and push in the top part, and it's nice and smooth. You are right...at high speeds, the Givi feels like Lennox Lewis is smacking you on the sides of the helmet. Over 80, if I don't tuck down, I can't even read freeway signs. Not the case with the MRA, but because it doesn't block as much wind, you get a little more gorilla arm syndrome at high speeds. Anyway, I like the MRA, over the Givi. Besides, you can put all kinds of words behind that acronym, like Mentally Retarded A

    That big barn door that Flying Dutchman has on his bike may be an option too. I've got the same problem you mentioned. I can't read the signs or see what's in my mirrors with the stock screen. 30 minutes of riding yields a horrible headache.

    I wish there was a way to sample all the screens. The Givi is cheap (compared to others), and I'm sure the offerings from Cee Baileys and BMA are going to be top notch (when they hit the market). I am not so much concerned with getting tons of airflow (while it's nice), I just want smooth air. I've had the bike over a week and only have 600 miles on it! I did that in 2 days on the RT!
