My "small" extender for my Versys-X windscreen is a big success. There is just one problem: wobbling fore and aft. When I am on the motorway, there is a lot of turbulence from the cars and trucks ahead of me. As a result, my windscreen and its extension wobble like jelly. Once I am away from the traffic, in "clean" air, the wobbling greatly reduces.

To provide mechanical support to the windscreen, I have ordered a GPS mount. (See below). I will mount a rubber spacer on the top horizontal bar of the mount, to press up against the windscreen to support it. That should reduce the wobbling.

Has anyone else tried this?

No but I feel your pain. After installing a large, aftermarket touring screen and bracket (MadStad) my windscreen and cowling vibrate a lot; it's like a sail up there. The buffering is gone and it's an amazing setup but I don't like the extra shaking. I've been trying to figure out a way to brace my cowling internally, to add strength so it can support the extra pressure from the new bracket/screen. Of course in summer I have a small fly screen and it's not an issue.

Make sure there is nothing metal anywhere near the screen; rubber may work but it wouldn't take much for a screw or the edge of the bracket to push past the rubber and into your screen. I guess the spacer will eliminate that possibility.

I know that I will not be able to eliminate all the wobbling, but I can reduce it to an acceptable level. This will also reduce the flexing of the Versys-X screen and maybe reduce plastic fatigue (is "plastic fatigue" like metal fatigue?).

The "small" windscreen extension significantly reduces air pressure on my upper body, thus reducing rider fatigue on long-distance high-speed touring (getting to and from those unsealed roads).

My screen extender is a different design from your one. It has two attachment points instead of one. I hope it will be up to the task, but if it breaks, I will do what you have done and get the one-piece larger screen that you have. Two of my Versys-X-riding mates have the same screen, so that's what I will get if my extension shits itself and goes south.

I installed the MRA windshield and vario spoiler and have no issues. No turbulance on helmet (until higher speeds 55 plus) and NO wobble. I don't need to ever put the helmet visor down unless to protect from flying objects (mostly bugs). Best part there is no "pushed out or sucked in" when going by semi's on freeway. I believe the secret is installing the windshield with adequate spacers between the dash and shield, that will allow air to flow up the inside mixing with air coming over the front side and equalizes the air flow.

The MRA windshield looks quite small like about the size of the OEM windshield. Does it stop the helmet buffeting? I found the OEM to cause helmet buffeting and noise to be unacceptable. I've just finished a time consuming project on windshield design for the X300 and learned a lot about what it takes to stop the noise and add protection.

Try shifting the "Angle of Attack" of the air flow which might solve your problem. If a wind screen (Angle) is wrong mounted againt the flow of air then you will encounter all sort of problem. To reduce air turbulence from traffic keep a safe distance which might work.

I'll measure the MRA, it's a little taller and wider. You can't use bark busters at least that is what they say because of the width. And yes I played a lot with spacers to get the angle of the screen right for me.

Here's a photo showing the combination of GPS mount and a roughly made (from scrap wood) "spacer" that fits between the horizontal bar of the GPS mount and the stock windscreen. This "spacer" is essential to enable the GPS mount to "brace" the stock windscreen.
Without this bracing, the stock windscreen (with windscreen extended) will wobble significantly on the motorway, with a displacement of 3 cm back and forth. With the bracing, this wobble amplitude is reduced down to about 0.5 cm (with most of the wobble being from the linkages of the windscreen extension itself, which I can't do much about.
This bracing, while crude, is very effective.

The stock windshield with the extender with no other support will fatigue and fail at some point. Your spacer is good idea and can be refined using Polycarbonate perhaps and virtually disappear. With my " winged version " there was a side benefit. The wings as they, for the most part, are leaning at an angle on the stock windshield and I put little peal and stick rubber feet to stop the slapping noise. The wings keep some pressure while the bike is above 15 mph on the stock windshield and there is no wobble. I fell into that one as I didn't exactly have that in the concept while designing and installing the wings. I have another video coming soon showing as addition of a beefed-up camera mount in front of the stock windshield that is utilizing the adapter and 1/2-inch aluminum billet riser. Crazy possibilities.

Good suggestion about using polycarbonate for the spacer.

I will keep the wooden spacer in place while I evaluate the performance of the GPS mount. If all goes well, in the future I will build something a little more refined.
