Givi confusion

Please forgive my confusion I have had my givi screen for about 2/3 weeks to stop the wind blowing in face,it works wonderfully well however i now get beaten up from every other angle the wind blows straight down my neck is this the norm??? or am i rideing with a crazy ghost??

That was the major problem with the Givi for me and a lot of others. I changed over to the Clearview Medium, and have had no problems.

John, ... Thomphoto.. I have a Givi.. only wind shield I have ever used, so I may just be ignorant about what both of you have described. I am not aware of any turbulence from any direction unless there is a strong gust when I meet a truck or there is a storm brewing. I usually ride at near 60 mph speed, but have ridden for a short time ( I emphasize SHORT ) at 110 mph. I have placed my hand above my head to see where the air flow seems to pass over me and it is a good 6 - 8". When I have ridden in the rain, I notice the rain dropplets are passing over my head in the same way. My screen was on my scoot when I bought it, so, I don't know if it was modified or not. I don't think so. I am 6' tall and ride all the way back in the seat. I have removed the butt rest temporarily so my wife can ride with me. This places me as far back on the seat as I can possibly sit. I can't imagine where your problem is originating. Does Givi make more than one height wind shield?

I will try removing the butt rest as for when it raining i still get a wet visor im 6'2 thanks for the feedback

thomphoto thanks for the info but looks like im gonna have to get used to the givi

Hi John,

Sometimes the problem is your helmet. I don't get that problem. I have an HGC SIMax II helmet now. Before that, I had a much less expensive one, and had a lot more wind shear.

M-

I am 6'2", have a Givi windshield, and removed the back rest so I would have more leg room.

At speeds less than 45 mph I do not notice turbulence. When I hit the highway (50-75 mph) I can feel the wind eddying back and pushing against the back of my head. At the higher speeds I feel the tension in my neck from resisting this force.

Another bit of evidence: I have my own built-in wind vane, a long ponytail (I may have cut back on riding the Harley but I haven't cut my hair). It tends to blow forward, wrapping around one side of my neck when I reach speeds around 55 mph. (See Mom?? I told you there was a legitimate reason for not cutting my hair!)

To be more accurate: I just rode to church and back. I put my hand up again and the air is barely clearing my helmet. I still wasn't getting anything significant down my back, there may have been a small eddy just past my back. Until you two mentioned this, I was completely unaware of ANY turbulence. I sure don't feel any tension at the speeds I usually ride (60) Tonight I drove 65 mph GPS.
Robin, please refrain from bragging about having hair. Some of us are a little self conscious about that. Same goes for teeth and you know what....

:lol!:

Though that will not stop my from telling my sons that their hair needs to be cut.

I have a Givi and cut it down about 2 inches. I am also 6 feet tall and have removed the buttrest to get maximum legroom. I have noticed that whatever wind turbulance there is it comes at me from a different direction than all the other windshields I've had on other bikes. Like RobinC above when ever I get a blast from a truck coming from the opposite direction it seems to blow from my back to front. On all other bikes I'ved owned a truck blast would have come head on. I rather like this change in direction. I also get almost zero helmet buffeting with the Givi. On all other bikes it was always more of an issue. I don't know if it's the Givi or the Swing(probably a little of both) but this combination has given me the most comfortable ride of any bike I've owned as far as wind turbulance goes.

Yes.

I actually don't agree with dspevack. Best to my knowledge there is only one size Givi windshield is available for SW, D214ST. Clearview offer 4 sizes (S, M, L, XL). They are 22" (+1" over stock windshield), 24" (+2.75"), 25" (+3.5"), 26.5" (+4.75). There is a description on their website of how to determine a size which is correct for you. Also, if you call them and give them your "dimentions" (height, inseam) they'll tell you what they recommend. Give windshield is 26.5" high. I wanted to buy Givi from the day one but I am only 5'6" and according to Clearview I only need 1/2" over the OEM windshield. I also don't like idea of cutting a windshield although it is doable. Givi is also much cheaper than Clearview. I am living with OEM windshield for now. With 90deg temps we have had for the last few days wind in your face actually feels nice.

I installed the Givi and I hated it. I am only 5' 5 and it was way to high. I had it cut down. It was better but it felt like a wind sail instead of a wind shield. The wind was blowing me around from every direction. Each to their own. I took it off and have the stock on and it works just fine. Got the Givi back in the box in the Garage.

I've been wrong before and I'll be wrong again.
This may even be one of those times.

Hi everyone,

I use a laminar lip on my S'wing and this to me offers good weather protetction whilst still being able to see over the top, noise reduction, buffetting reduction and you can adjust it easily.... That last option is quite important since if you have it mounted too high, then you get buffetting / turbulence ....

Anyway to get to point, I made some modifications to the windshield on my bike that significantly reduced turbulance and buffetting. I'm sure this would also work on the S'wing.

The following is an email I sent to a bike forum describing what I did....


Hi Everyone,

Having been considering aerodynamic spoilers etc, (see web sites below)

http://www.saeng.com/subcategory.php?category=51
http://www.r1200gs.info/misc/aeroflow_saeng.html

I decided that it was a bit expensive for something that may or may not prove useful..... Plus I can't find a UK supplier...
Thus firmly in Blue Peter mode, (childrens DIY TV program) I decided to have a go myself by spending the princely sum of £5.89 or something like that in B&Q (DIY store) and bought some self adhesive brown rubber draft excluder which I spray painted black and then stuck to the leading edges of my screen.... I mean what with the cable ties to stop the screen deforming at speed, (the wind shield would dislodge from its mounts at 100mph, and the bike tops out at 130mph so that was no fun, but the cable ties work a treat, and the screen holds up well) the screen not exactly going to look any more naff than it already is



Not only did it stay stuck on, even at high speed, it appeared to work! Wind noise and buffetting a little reduced, but even more strange the wind noise with my visor open was much more reduced than before, and quieter than with the visor down and closed ?!!! Now I am able to ride at 90mph with the visor open as opposed to the 70mph before..... I could even ride at 55-60mph with the front pivoting part of my modular helmet in the fully up position. Before fitting the draught excluder, those speeds would have been much more uncomfortable with the helmet in open mode.....
It works best with the rubber excluder all the way round the screen as in the pictures below. Initially I tried just the top edge first of all, but it didn't seem to make that much difference.





What an irony! who would have thought a bit of draught excluder could make such a difference, on a bike?!! I suppose I'd better add here that I also wear glasses, so they also offer a little eye protection when I ride.

The draught excluder rubber is very soft and light, and who knows who long it will last? But its worth a try, and a lot cheaper than that Saeng edging. However, If my Blue Peter job doesn't work out, then I might well buy myself the real McCoy, even if I have to get it from the USA.
Now its just as fun riding along on my Divvy with the visor open, and instead of needing ear plugs, you hear the engine much clearer above a very reduced wind noise...... And it sounds great! I shall have to try it with my open face helmet which I bought in the Lidl sales to see if they are any good..... I've always been a full face helmet guy, but for commuting in summer when its hot, maybe an open face will be more comfortable?!
In summary I think the main application here is potentially a massive reduction in fatigue due to buffetting and wind noise on longer trips, and the advantage of being able to keep your visor open at relatively high touring speeds. For now anyway, my Divvy seems to offer better top half weather protection than my BMW K100RT that I used to have years ago. I'll report back on the open face helmet in due course.

Happy Riding!

That was a few months ago and the Mod is still going strong, and superb with an open face helmet in the hot weather..... By the way those black wind deflectors on the sides of the fairing, kick out the wind blast a few inches, and offer good protection to my hands.... They are none other than laminar ears for a Silver Wing!!

Ive solved the problem just need another month down the gym or i could slow down its fine under 50

If you have the stock w/s and want a good solution find a w/s off off a m/c that has been discarded because it it cracked in the lower section. Take a band saw and cut it in to a "laminar lip" fasten it to the existing w/s with valcro and use a couple of the larger fold over clips for safety to make sure it stays in place. I fixed my problem and can remove it when I am just cruising around.
Just Old Dave in western Nebraska usa

I have now found that without the back box on its a whole lot better (not perfect)but better

john im 6-2 and im very comfortable with my givi shield and i have been running this shield 3 years and 28,000 miles on both my 05 and my 07.

Took mine off today and put my original back on and have to say I think I prefer the original.... Im so used to riding naked bikes it always felt odd the quiet and the direction of the flow I also think the stock is better at high speeds where as the givi is ok up to 50/60 its a bit too tall after that so it feels like the bike is forcing through the wind ,also because I can hear the wind rush again I cant here all the rattles so bonus


P.s
If any one wants a givi screen I know a man whose selling one lol

I had the same problem with my Givi windscreen...it feels like somebody trying to push me into the handlebars from behind at freeway speeds. If you sit and stare at the windscreen long enough, the reason becomes apparent; the 'hand guard ears' on either side of the main shield are pointing forward INTO the wind. Every other surface on the bike is angling back in some fashion, and then there's those crazy 'ears' angled forward, digging into the slipstream. Its the worst bit of aerodynamics I've ever seen. Shame on you, Givi! As they carve into the wind they create the intense buffeting that you're noticing from behind and from the sides.

I masked the screen and cut them off with a sabre saw and it completely transformed the performance. Now it affords a much smoother and quieter ride than the stock unit. Give it a try before you give up on the Givi!

Any chance you could take a picture of the finished product and post it ?

I've got a photo in my album that shows it fairly well. Check it out.
