 UPDATE:

So I had a chance to try out the modified stock screen on a two day trip last weekend. While the holes that I cut to mimic the holes in the Vario screen did reduce the buffeting they did not illuminate it, and there is still quite a bit of turbulence and wind noise if the screen is raised more than about a half an inch from its lowest position.  I'm still going to try mounting the laminar spoiler from my Vario onto the stock screen to see what difference that might make, but at this point, after the performance of the stock screen over the weekend, I'm skeptical it will be the solution.

Hi,
        Everyone has to make a choice but....

I want something smaller than the OEM screen, but do not like the "Copperdog" even though it looks good!

The MRA Vario, for me in Florida, is "just right" (to me) for a year round screen!

I ride with the screen all the way down and my helmet face shield up (with sunglasses) till I run up to about 60 MPH...

Then the screen goes up, and the face shield goes down! ;D

I really like the Vario in terms of the clean air that it produces. As a matter fact, about an hour into the ride last weekend I was kicking myself for taking it off the bike to try this stock screen modification.  If eliminating the buffeting were the only concern then I wouldn't have looked any further than the Vario. It does an outstanding job in that respect. The only reason I'm messing around with all of this is because when I heard how unbelievably quiet it was behind the Vario if I just scrunched down an inch or two  I could see how much more peaceful and relaxing a long ride would be if I could get into that bubble. That, and the fact that having just spent a bunch money on the Vario i'm not excited about spending more money on other screens are brackets if I can help it. All of this messing with the stock screen is only costing me a little bit of time. If mounting the laminar spoiler from the Vario on the stock screen doesn't work then the next step will be looking at the X-creen.

Next step, after mounting on top of screen,,, remove the upper lip and try again...
Then (if that doesn't work) MRA X-creen...

Ride safe, Ted

The weak link in the windshield system is the flimsy pair of black plastic "holder plates" (to use the terminology in the manual) that secure the windshield on the bike. If you use the vario, I recommend checking the holder plates periodically for cracks. I had a handful of these plates crack around the two screw holes even before installing the vario and got in the habit of carrying spares on trips. After reinforcing the plates with glue and wire in the cavities on the backside of the plates they did not crack anymore. When I installed the vario and they cracked again, rather quickly. This was frustrating because the vario provided my helmet clean air for the first time (I am 6'5"). To allow continued use of the vario I employed large metal washers bent to conform to the plastic plate (along with longer screws since the screws were no longer sitting in the plate's screw recesses). This served to distribute mechanical forces over a larger surface area of the the plates. No plates have cracked since.

Those holder plates are a joke! I ended up getting tapered plumbers washers then used slightly longer screws. The look good and my problem was solved with those holders cracking

So, update on the progress with this experiment.  To recap, I had taken my stock screen and cut in it two holes to match the holes that the Vario has in it, hoping to reduce the back pressure and buffeting.  It did, but not by much. 

So, I then took the laminar spoiler off my Vario and mounted it to the stock screen.  I drilled the stock screen in the flared lip at the top of the screen to maximize the height of the screen/spoiler combo.  I had it out for a highway test run today and it was indeed tall enough to get me into the quiet envelope below the airstream.  I'd say that it pushed the airstream up over my helmet by about 1 inch with the screen raised to its highest position.  There was still a small about of backpressure, however.  Not buffeting, but more of a steady soft push against my back.  Not uncomfortable for short trips, but I could see that it could get to be aggravating over a longer trip.  Additionally, the stock screen was flopping all over the place whenever I passed a truck or other large vehicle.  I'm concerned that over time the extra force being placed on the screen by the spoiler at the top of the flare might cause the screen to break the plastic plates. 

So, I took the spoiler off and then cut the flared lip off of the top of the stock screen and remounted the spoiler as high up as I could reasonably mount it.  That pretty much eliminated the pressure on my back, and the stock screen/spoiler combo produced almost as clean an airflow as the Vario.  That also solved the flopping problem.  However, the two inches that I cut off to get the flare off put the airstream back to hitting me in the helmet again, so I was back to square one. 

At this point, if I'm in the airstream anyway I'm putting the Vario back on.  It seemed to be a little better at smoothing out the airflow than my contraption.  I guess my next step, if I decide to spend more money, will be to try the X-creen.  I'm hesitant to spend the money, though, without having any idea if it will solve the problem. I'm also considering a new helmet.  My Arai was apparently designed for the more aggressive riding position of a sport bike.  In the upright position on the Connie I can hear wind noise in the front air vents.  If I tuck my chin to mimic the riding position of a sport bike it stops.

So, if someone wanted to get almost the performance of the Vario without having to buy a whole new screen, they could buy the spoiler, cut the holes in their stock screen, cut the flare off, and get a pretty good facsimile.  Or, for not that much more, you could just buy a Vario and spend the time you saved riding and enjoying it!

TC14,
You do have all the rubber spacer gaskets in place right? (4 of them total) Also the center bolt with the nylon washer under it? I am really interested in figuring out what is happening here since I use multiple screens in a year and have zero issues with any of them.
Matt


I noticed my windshield seems to slide around a little so I took it apart. I don't see the 4 rubber gaskets and only have one nylon washer that doesn't appear to be doing much. I looked at the parts diagram and the way I read it, bolt (#92172) goes through the cover (#14091) then through the damper (#92161A) then through the windshield and then through the lower damper (#92161) and finally into the bracket. 

I appear to be missing the lower damper which leads me to believe that the rubber spacer gaskets built into it.  Can anyone confirm this?

Thanks,
Berk

Berk,
The lower rubber gaskets have a raised ring that fits around the bolt boss on the windshield bracket assembly. This will keep the screen from moving around. There are 2 nylon washers needed for the center bolts, one on each side.
Matt

I am assuming you have a pre '15 bike as the mounting gaskets are different on the '15 and up.

I have the MRA Vario on my 2016 C14.
The best bang-for-the-buck mod yet.
An impressive improvement over the stock 2016 windshield. My 2008's windshield was better than the 2016.
I'm amazed how a shorter, vented windscreen performs much better aerodynamically than the taller, vented, flimsy stock windshield.
I'm 73", 34" inseam, standard saddle with a Shoei NeoTec and the MRA is a much quieter ride with the screen down. I seldom raise the windshield.
A 2016 needs an additional 6 KAW part numbers (hardware) to fit the MRA.
Any C14 aftermarket windshield will fit 2008 up to 2017 C14, regardless what most website retailers state.
I purchased my KAW parts from Rocky Mountain ATV&MC in Payson, UT. They had all the parts in stock, shipped that day and arrived to me
2-day's later.

Matt,

Thanks for clarifying. I have ordered two of the lower rubber dampers which I am missing. That should keep things from moving. You're right, I have a 2008 which I bought used with an aftermarket windshield. I've tried to attach a pic, can anyone tell me what kind this is? I usually keep it all the way down except for highway riding in cooler temps.

He also gave me the original stock 08 windshield which I have not tried yet, it is shorter than what is currently on the bike so maybe I'll give it a try this summer.

Thanks for the help
Berk

Man, this post really came in super handy for me!!
Great reading all your great inputs as usual, thx guys!

So, I purchased an MRA Vario from Twisted throttle for my '12 connie; I came home from work yesterday, and saw it finally arrived at my place after a full month of waiting (was in back order, had to be ordered from Germany - I'm in Canada).

When I open the box, I realize just how SMALL it is!!  :o
I was hesitant to take it out of the film it comes wrapped in, thinking maybe I should go for the x-touring, or whatever it is called, the larger version (also 100 bucks more expensive).

I'm 5'10" and I have a huge melon, so my helmets are always XL or 2XL, which obviously creates more drag.
I truly hate the buffeting and extreme wind noise (then again, it could be my crap helmet), that I feel when above 40 mph on the connie. I have ASTs risers (2" up and back), so my riding position is more upright.

Mattchewn, Steve, do you think i will find the bubble of peace and quiet behind the Vario? Help me guys! ::)
Best,

JD

Yup.

I have the same windshield - and the same "melon" problem.  None of the 'premium' helmets come in my size, so I'm stuck with helmets, that though safe, are noisy and not nearly as nice as many out there...

I probably sit a little higher than you, I'm 6', but have short legs, so sit as high as if I was 6'3" or whatever...  I found the MRA Vario helped some, but doesn't really fit the " bubble of peace and quiet" you're describing.  I blame the helmet, both size and quality, for the noise and buffeting...  Not much I can do about it.  Still better than not riding...

It works very well for me.  I'm 6 ft with a 32"inseam and love the smooth airstream off the MRA Vario.  I wear XL helmets and don't experience buffeting behind it.

MRA Vario Xcreen + Madstad brackets work great.  Smooth Air and super adjustable.

JD...Hilarious! :rotflmao:

I also have an XL melon, but I am also vertically challenged...at least compared to most the people on this forum.
Are all Concours riders 6ft. +???

I'm 5'8" with 30" inseam, I think that makes me one of the shortest C14 riders on the planet.  The dealer never spoke of a height requirement.

Did you decide to install the MRA Vario shield?
If you did, how do you like it?

I'm considering staring a new windscreen thread for "shorter" riders.

I'm 6'2" with a 32" inseam so I am long in the torso. I ride a 2012 C14 with a Corbin 2 piece seat reworked by Lamm. I have a CB screen with the MRA spoiler added. I don't notice the back pressure as much as I do wind noise. I ride with a Scorpion Modular and also have another brand  modular which was supposed to be the quietest modular but ended up with more wind noise than the Scorpion. I still have to raise the shield higher than I want to get some control over the wind noise. Considering either the MRA Touring or MRA X Screen. Do any of you have an opinion on that issue?

Hey Tim! I'm kinda like you (5'10"), so I belong to the "short" end of the spectrum, when it comes to connie riders.
Hey Mattchewn, how's the air up there at 6'4"?  :)

In terms of the Vario, lately i've been riding with it all the way down, because it's been hot as f**k here in Toronto. Riding it like this obviously gives me a lot of wind, but somewhat 'clean' wind. I mean it isn't buffeting and back pressure, just a nice stream of wind on my chest and helmet. Besides, my stupid Shoei Qwest (the worst bang for the buck in terms of helmets, IMHO), fogs up like crazy if i have no air hitting it.

When I lift it all the way up, I would say i'm almost in the Bubble of Silence ("Get smart" anyone?). You should be pretty ok in it at 5'8". Is it not working well for you?
Best,

JD
