Does yours flop around much?...

I have the BMW touring windshield and just wondered, from those of you out there similarly equipped, does it wiggle much at highway speeds from wind, bumps, etc?

Thanks...

Mine doesn't flop or wiggle at all. It's pretty much rigid all the time.

Mine moves a little, especially when those big strong truckers go by (not that there's anything wrong with that).

You have to frequently check the bolts that hold the upper brackets to make sure they are tight. I lost one of mine.

I had one brace that kept getting ooose after an hour or two causing my touring screen to wiggle....I carried a number 9 allen/socket wrench to tighten it. Took it to the shop for service and had the dealer really tighten it and replace a brace that I bent when I dropped the bike. It is dead solid now and doesn't vibrate, but there is some buffeting at high speed (over 80 85 mph)..I am 5'10"

if you really tighten the bolts which attach it to the bike it should not vibrate loose.

Not since I changed underwear brands.

In all seriousness, the windshield mounting system on the Roadster is perhaps the weakest part of the bike's design. Other than surging of course with many of these motors.

My touring shield does torque around the center of the moment arm located between the lower and upper mounting brackets at low speeds when I go over bumps. At high speeds, the wind blast pushes the upper part of the shield downward a bit where the resulting tension keeps the windshield steady. So at highway speeds, I don't notice much motion.

I agree with the bolt tightening statements. My "wiggle" became progressively worse so I had to break out the 6mm. Tight fit under there.

The wiggle was more than I could bear on rides of more than one hour. Switched to an Aeroflow Sport shield that does a better job with no extra movement at all.

You guys that had/have wiggle had something wrong with the installation. I had problems with the original installation of my touring screen and it was discovered that the factory installation parts included screws for the upper brackets that were too short. After replacing those with longer screws I've put 30K miles on mine with NO wiggle whatsoever. But I've only tested it up to 130 mph - I don't know what would happen if you were to go really fast...

And, yeah, the upper bracket screws are a b**ch to get to.

I just had new tires put on today and had the mechanic (he only works on BMWs...and he had an R1150R before) throw a quick eyeball on the screen installation. Turns out one of the rear PITA mounting brackets was a smidge loose. Halelujah - NO MORE WIGGLE!

I have the 380mm touring screen and I found that it does loosen up after a bit. Probably the crappy roads here in Alberta. A little locktight fixed the problem

Also put a little locktight on the screws holding the windscreen in place. Don't know if that's a no-no, but voila, no loosening.

Loctite is supposed to be verboten because it is bad for the plastic of the windshield. But if you're careful, it should definitely help to prevent the bolts loosening.
