Laminar lip: reduced turbulence?
Does anyone have good results with the laminar lip in significantly reducing wind noise and/or turbulence on the R120GS? I had one on my F650 GS and didn't notice a tremendous difference> I am trying to decide between the lip or going with the Ztechnic Vstream screen.Any thoughts? I am 5'9".
My Laminar Lip saved my GS stock windscreen
I have a 2004 GSA and I'm 6'-3". I was getting so much wind turbulence that I was about to pay $$$ for either a Cee Bailey or Ztechnic. Then I saw a Youtube video about an Englishman who was riding the world with the same bike as mine and had installed a Laminar Lip on the stock windscreen - he was 6'-4" and said that it worked perfectly. I did some research and found a Lip that fit my bike for under $89 (including shipping), bought it and put it on.
I'm VERY HAPPY with the results and I didn't have to fiddle around testing that many Lip heights - I placed the Lip's mid-section parallel to the top of the windscreen and it worked great.
So, unless you have a couple of hundred dollars saved for a rainy day and don't have anything else that needs it, I'd try the Lip and see what you think. If you didn't like it you could always sell it on eBay... :rolleyes
Laminar Lip worked on my R1100S
I was skeptical at first about the Laminar Lip, but decided to try after reading a few posts and not wanting to possibly waste money on an after market windshield.
It definitely worked on my bike.
Recommend bolting to your windshield, but after you test the position a few times.
My Laminar Lip also came off at just over 60 MPH. It hit the top of my helmet and at first I did not know what happened. :dunno Then I looked down, could see that it was gone and thought it will be run over by the truck behind me. Luckily it landed in the other lane. There was not much traffic and was able to turn around and pick it up before it was run over. Amazingly, there were no scratches on the Lip, except some slight scrapes on an edge.
It is now bolted on. There is a lot of pressure at higher speeds and the way the Lip is shaped, the wind causes rotation of the lip. So the lower dual lock fastener is in tension and the upper set is likely in compression (until the lower dual locks start to separate). You can probably get by with just 1 bolt or screw on each side, but mount it low.
I just drilled through the dual lock pad and that is what I use for a soft material between the windshield and the Lip.
The R1100S windshield has a lot of curves in it and I do not think the Laminar Lip that I received was perfectly symmetrical. I was never able to get the open space between the windshield and the Lip to be symmetrical. (Maybe the R1100S windshield is not symmetrical, in keeping with the theme of it's asymetrical headlight design? :scratch )
I am overthinking this, I know. :p
Another Fan of the Laminar Lip
My current K100RS came with a Laminar Lip on the stock little shield and I fully expected to replace it with the fairly tall Aeroscreen shield I saved from my wrecked K75 with an RS fairing. Hasn't happened. That little baby seems to give as much protection as the much taller Aeroscreen. Both provide a turbulence free ride for me - and I get (got) bugs on the faceshield with both.
I would definitely give it a try. If it doesn't give you as much protection as you want, my guess is that you could get the results you want with a considerably lower after market shield and the Laminar Lip than with a shield alone.
As many have noted, getting a turbulence-free ride, especially if you want a bug-free faceshield, isn't easy. I would try the Laminar Lip on your stock shield and, if not happy, try bringing your left hand up to find out where the wind actually hits. I would wager several inches higher than with the stock shield alone. That would give you an idea of how tall a new windscreen needs to be to direct air and bugs to the top of the helmut.
Good luck and keep us posted.
Laminar Lips work, but....
Before I bought an Aeroflow I tried all manner of "cheap" solutions for my '05 R12GS's insane buffeting. One of those was a Laminar Lip. The Lip certainly "works." Most buffeting stopped, and the ride was much quieter. But, while the ride was improved, the shield shook violently at speed.
After a few weeks with the Lip, I noticed a very slight crack on the Lip at one of the Dual Lock contact points. There is no question in my mind that it was a stress fracture. While its rare, I had heard of Laminar Lips exploding off of bikes at speed, and I had no desire to be one of those. So, I bought an Aeroflow which transformed my bike. Four years and over 50,000 miles later its still as solid as a rock. It is, without doubt, the best mod I've put on my bike.
In my opinion you should be wary of cheap solutions to the R12GS's buffeting problems. I've heard of many people buying into cheap solutions such as the Lip, Tobinators, etc..., and etc..., and after spending the money that they would have spent on an Aeroflow in the first place, turn around and finally [I][B]get [/B][/I]an Aeroflow. If you're asking for opinions, I'd suggest that if you have noise and buffeting problems on your R12GS, you should get an Aeroflow and be done with it. Ignore those who say its ugly, after all, the GS is an ugly "form over function" machine anyway. And a Lip ain't the prettiest mod either.
Good luck, and let us know what you do.
