I also had terrible buffeting. I started with a MS 21" shield and at 70 MPH my head felt like it was in a paint can shaker. I tried angling the shield on all planes and that did not help. I tried lowers and it helped a little but the shaking made long rides miserable. I cut the shield down 3"s and that helped more than anything.

There were several issues I found interesting...

With a full face helmet I had no issues. With no helmet I had no issues. Only my half hat bothered me.

I have since put a fairing on the bike and it is perfect, no issues with or without a helmet at any speed.

I think it would be prudent to ask how tall he is, how tall the windshield is, bike, type of helm.. first. I dont have lowers and Im fine..

Lowers don't always fix the problem, sometimes it just reduces it to tolerable.

Like others have said, more info is needed, drivers height, windshields height & type, helmet, etc....

They say you learn from your mistakes, in that case, I must be a genius.

I have had several bikes, all Hondas except for a Kawaski dirt bike many years ago. I just bought my 1800T Friday and I love the bike. However I have never had anything with as much buffeting as I am getting. The air is coming right off my knees and straigt up. Yesterday I was trying to decide where the main problem was. I discovered if I took my left arm and layed it across my chest, just below breast height, it all but elemintated the issue, Obviously that is not a solution but it did help me determine that the air coming up in front of my knees was the problem.
Now, what lowers do I buy, I have got to have something that will help, I am leaning towards the Hondaline, who has them and do they help.

I think there is something to (to tall a windshield). It seems they create even more turbulence and drag.
With a 12" on the Fairing vs. the 7" it felt like more turbulence and drag. Switched back to the 7" and even though there is a little buffeting on the top of my helmet (in a no helmet state I don't feel it on the top of my head) the ride is or feels more solid at speed. So much so I will probably leave the 7" in place and let the little buffeting be a compromise.
Someone posted (it's all very touchy) and it is just that.

Yes Lowers will help. Here are mine.



That said, its all about position of the windshield to create the proper windflow.

If your getting buffeting really bad, try first lowering the angle (towards your bike) of the windshield a bit. Then try increasing its angle (away from rider) to make it taller and more flat. See if that helps.

If its a smaller windshield, you might have to lower the angle so the wind will rise over it and flow into your head. If you angle a smaller shield (and bigger one as well) more upright, to cover a broader area, the wind eddys around creating lots of turbulence circling behind the shield (IE your back, and head), ever wonder why sometimes you can get bugs stuck on the back of your jacket? This is why.

Remember, the shield wants to lay flat for the least resistance.


Its easier to see than to explain.

Look at this crudely drawn example I just quickly drew up.

Black = Sheild Position
Yellow = Air Flow



Shield too 'high', lots of buffeting immediatley behind sheild.

Sheild too low, less resistance and buffeting, but also less wind protection (defeating the point of the shield)

You have to find a good medium that will not create too much turbulence immediately behind the shield (on you), and giving the air a more efficient (less turbulent) route to travel over/past you. In the middle pic, the rider has good protection, and, the air flows at least PAST his head before starting to eddy around. This is what you are looking to achieve. However, variables such as Rider Height, Seating position, Windshield height, and bike type (or placement on forks) make that perfect combination different for everyone.

Also note, if you are riding two up, your 'perfect position' may put excess buffeting on the passenger behind you. You very well might have to adjust it for the passenger as well.

The wind that was kicking my head around was coming from the sides of my tank. It was running up my chest and hitting the lip on my half hat. Angling the shield did nothing and for some reason the lowers did very little for me.

Cutting the screen down helped more than anything else, well, except the fairing.

I have the NC Switchblade 2up and NC lowers, they pretty much stop the buffeting but the lowers push air directly at the grips making for cold hands
