I just got my 2008 1200c a month ago and have the standard height detachable windshield on it.

I ride with a 1/2 helmet with face shield.

The only time I have serious buffeting was when the helmet was cocked too far back on my head at 65MPH.

How tall are you?

Not to cause argument but that arai helmet my have been an auto and not a moto... but I am not sure. My arai profile dose not shake like that when it’s in the open air either did my shoie x-eleven. Only when i am behind the wind shield since it’s that which is causing the buffeting

 

Iclement,
We've got exactly the same symptoms. I've come to the conclusion that my buffeting is from air curling over the top of the shield or from behind as it comes in to fill the low pressure area behind the screen. When I put my arm across my chest or block the air coming up beside the tank, I get no change in the buffeting When I lay my hand on the top of my helmet, changing the aerodynamics of the helmet, the buffeting stops.

I tried changing the mounting angle of the shield to make it more upright, but that's made no difference, either. I moved it down so that the arched edge sat right on top of the headlight. That made no difference as well. I think my helmet and this shield are just not going to get along so I've ditched the windscreen for the time being. Will probably sell it on at some point.

Felt like I needed a wind tunnel to see what the heck is really going on!

 

Yeah I have also noticed that there is some air that rolls over the top of the shield and I was praying that it was the air that was coming from underneath because those wind deflectors may help some in that area. For the top I have no idea what to try except maybe a different shield, and/or a lower seat. I just recently sold my sport bike to get a cruiser that I could ride longer distances on and now running into a whole new set of problems. I am now wondering if I should have got a dresser/ bagger, never thought the wind would be this big of a problem!

I think in order for the wind to not roll over the top of the shield it would have to be slanted with the top forward and the bottom inward which would look stupid and that may be worse…

I am about 6 ft and my helmet sticks up about 1.5-2 inches more then with out, when I am not wearing a helmet I can feel the turbulent wind hit the top of my head so you are probably right. I can also feel wind hitting behind my head somewhat so it may be a 3 part problem, air from below, turbulence over the top, and the wind drag from behind. This may be more difficult to correct then the wind defectors are capable of but I will wait until I try them and report back. They should arrive on September 2nd.

I feel like I am trying to break the sound barrier with this aerodynamic lingo, just want a comfortable safe ride I don’t know if it’s just wind drag or a low pressure zone heck maybe its both.

Now were can I find a wind tunnel…

 

I may try and find a seat with a back rest and ditch the windshield, this way I will have something to rest may back against, that and some highway pegs and I should be able to just relax instead of flexing muscles to stay upright.

That mustang seat with a back rest looks like it may do the trick!

Here is a link http://www.jpcycles.com/productgroup...8-A79D4E8CA216

This and a passenger back rest and we may be in business, not giving up on the shield just yet though…

 

There is a "touring" QD shield. I got a big improvement by going to it. I find my 3/4 helmet is good also - and best without any face shield.

 

BWLucky13 mentioned a rubber lip that's claimed to deflect wind up and over the shield. It seems like it would work. I'll try to find a link to it. These attach to the outer edge of the shield like the moulding and rubber seals on car door edges. In fact I have actually seen car door edging used on motorcycle windshields, but have no idea if they really work. It's a fairly cheap experiment, though. The bad thing about a setup like that is that if the top edge of the shield is in your line of sight, that's about 1/4" of wind deflecting edging blocking your line of sight. If the shield is low like mine, the wind might be deflected right at the top of your head which would not only defeat the purpose, but aggravate it. Like I said though...$15 is a cheap experiment, IMO.

lclement and Pitts2112, you both seem to have issues with the wind coming OVER the shield if moving left arm in different positions don't work. That gives me pause to suggest lowers....or even Flapp's Aerovest (sp? I'm gonna have to get one of those). I think one of the main reasons I don't notice any buffeting is my head is fully sticking up from the top of the shield. I truly have the wind in my face (and whatever road debris gets airborne as I'm riding by). Perhaps if I had part of my head in the low pressure area behind the shield and part of it getting pounded by wind coming from either over or under the shield....or even BOTH...maybe I'd have issues too. I don't know.

I've had multiple trips of 200+ miles on interstate in different weather, wind and temps with EACH of Daytona Skull cap (with short sun visor), HJC 3/4, HJC modular and just lidless...10,375 miles on my present scoot, most interstate or interstate-type highway. 9,500 miles have been with a shield.

In retrospect, I DID rent a Sporty with a standard height shield before I bought my current one, and didn't like it at all. Although I would hesitate to actually call it buffeting, there was an awful lot of swirling wind behind that shield where I was sitting, that was annoying. The top edge was also in my line of sight. Was wearing the HJC 3/4 and got the bike up to 100 mph on I-35 between Austin and Waco once (I'm not really a maniac...I've just told you about the ONLY two times I've met or exceeded triple digits on a bike).

So yeah, I do understand about wind and windshield conspiring to create discomfort, but I've just never experienced head buffeting winds like you both have described.

It may have something to do with the shape of my helmet and I've thought about borrowing a mate's helmet to see if that makes a difference. But, other than that, I've ditched the shield in the meantime. The wind on the body is not nearly as bad as the paint-can-shaker treatment I'm getting on the head!

 

taking it off would work
