Helment Buffeting behind Windscreen

    I have my new bike with windshield.

    I find that at any speed over about 40 - 45 the turbulence created by the
    wind flowing over the screen moves my helmet so much that my vision blurs.
    Aside from tiring one out much more quickly if is simply uncomfortable.

    I have heard of something called a Laminar Lip and someone claims some other
    product which attached to the upper edge of the windscreen resolves the
    problem.

    Anyone have any experience with these products?

    From what I've read, adding lowers helps. I'm planning to try it soon.

    Part of the problem is air that comes from down low and rushes upward near
    the rear of the tank, at least on my Aero. I rode a friends Sabre last
    weekend and had no problem, I think because I was closer to the windshield.

    Using my hands to determine where the airstream is, I do feel the current
    above the windshield dropping just low enough to get the top of my helmet. I
    would think that adding lowers would lower the air pressure where I'm
    sitting and cause the airstream from above the windshield to dip a little
    lower, making the problem worse. I hate to have to spend money on
    experiments! People who have added lowers claim that it works (based on
    Cruiser Customizing product reviews), but then they may just be unwilling to
    admit that the money they spent was for naught.

    I would really like to cut my windshield down enough to see over it, but I
    know there will be aerodynamic consequenses.

    Usually helmet buffeting is caused by wind going over the windshield to
    the top of the helmet and below the windshield and up your body.

    Lowers will help the buffeting from the windshield if the wind is being
    re-directed underneath the windshield and up. You can test to see if
    your wind is blowing around your windshield by taking your arm and
    having it hover horizontally in front of you while you're riding.

    Use your discresion when letting go of your handlebar. Only let go of
    the left grip when you feel comfortable. This works best when you use
    your left hand (non-throttle hand) and hold it about 2-3 inches away
    from your body. Your elbow and hand should be even so that your arm
    makes a kind of shelf. Just like if you were trying to cover up your
    nipples with one arm, except your arm is 2-3 inches away from your
    chest. If placing your arm in front of your chest stops the buffeting,
    then the lowers will help. If the buffeting continues with your arm
    held in front of your chest, lowers will not help.

    Please feel free to let us know if you have any other questions.
