Windshield landing zone on a ’12 RT, can it be adjusted?

As some have noted before me the windshield lands differently the first time you put it down after turning the bike ignition on from the next up and down actions after that first time. It seems like it is trying to figure out where the bottom is the first time it lands on its down setting and after that it has its bearings and knows where to go, where bottom is.

So when I turn on the key and make the windshield go down the first time it squashes the rubber bumpers and makes an ungraceful plastic on plastic landing as the black shroud under the shield contacts the dashboard. Ugh! My old 07 RT did no such thing. That does not seem right, so in an attempt to understand what was going and maybe correct it I disassembled my front end plastic today, removing the windshield, arms, and front cowling. Lots of interesting stuff up there, like the Sirius receiver antenna, wiring for the radio antenna, and large ground strap. Except for these last couple of things the Haynes manual I just bought was very accurate for the disassembly process, and it was easy to follow the pictures. Also kudos to the BMW engineers who made almost all the bodywork attach with a single screw size, yay!

So, my question after all of this is that I noticed that the windshield motor has a small black screw on the end of it (on the riders left) that looked to me to be a lot like an adjuster screw. It is at the end of the windshield motor before it makes a right turn into a gearbox that operates an axle that makes the windshield up and down arms move. I could not find anything in my Haynes manual about this screw or adjusting the windshield. Yah, I know, I should have taken a picture. But anyway, for those of you who have an official manual or may have encountered this, is this an adjustment screw?

My windshield comes down hard on the bumpers the first time then does not get within ½ inch of them on successive up and down actions. I think it can do better and I would like it to land softly on the bumpers when I put it down first and then do the same on successive actions like my old ’07 windscreen did. Can it be adjusted? May common sense and manufacturing experience tells me this should be so, but maybe some of you know better…

Thanks for your input.

Re: Windshield landing zone on a ’12 RT, can it be adjusted?

My 2012RT does the same thing. I looks like it is hunting for a park position. But it only does it once I guess after initial power up. I am not worried about it. It is probably in the design of the windshield assembly. I do not recommend making any adjustments if there is nothing wrong with it. Manufacturers make changes over the years on similar models either for improvements or design changes. Leave it alone this is normal operation. Do not try to fix or adjust something you think may be wrong and yet is operating perfectly normal as per the manufacturers design. Not everything is in the service or repair manual. Some parts or components are strictly R&R (Remove and Replace).

From the service manual.
Installing windscreen holder
Installing entire top section of fairing
Connecting BMW Motorrad diagnostic system to motorcycle
Initializing/calibrating new parts

Disconnecting BMW Motorrad diagnostic system from motorcycle
Installing holder for windscreen
Installing inboard cover
Installing cover for instrument panel
Installing windscreen
Installing covers for both mirrors
Installing mirrors
Installing right-hand trim panel
Installing left-hand trim panel
Installing seat
Final check of work performed

Look at step 3 and 4. I suggest not to touch it.
This is strictly a R&R part.



Ride the Bike and enjoy it.

My '12 does the same thing, but I haven't noticed the grinding plastic on plastic sound you're describing. If you're close to a dealer, maybe they could take a look at it for you. Ask them about that screw as well to see if it's some sort of adjustment screw for the motor.

I'd say it's just normal operation, but that grinding sound makes me think otherwise?

I think I will follow your advice and ask the dealer. It just does not seem right that plastic should contact plastic on the first down action after power up.

I also noticed that the plastic shroud that sits on the arms under the windshield was changed between the pre-2010 and current RT model. The older shroud has less plastic in the center and sides, so maybe I will hunt around for a used one of them to see how that fits. Might also make it easier to clean it off on the inside as thats just about impossible without taking the windscreen off on my 2012 RT. Annoying!
