    Hi all -

    I'm looking for someone who installed the air deflectors (see pic attached) from Guzzi on his (hers) bike... Do they work? I'm curious to know more about their effectiveness before paying 100+ USD for a pair.

    Thanks!

    I would say yes. In my case (6.1/32" inseam) they have reduced buffeting significantly. To reduce buffeting, I first allowed more air flow on the inside of the wind shield by inserting spacers at the lower mounting points of the wind shield. Worked pretty well but not perfect. I then added the lowers and they changed the flow but it was not really an improvement together with the spacers. I then removed the spacers and kept the lowers, and it works well.

    I first added a Laminar Lip, which reduced the head rattling turbulence I experienced significantly, but had the effect of pulling me towards the screen, into a lower pressure area. I added the lowers and this effect disappeared. The combined effect is quite comfortable. I have no experience of the lowers only.

    They absolutely work. Most people don't realize that the buffeting they get with a windshield is caused by air coming up under the windshield. The lowers help to prevent that airflow.

    That said, your results may vary. But, I don't think you will be disappointed.

    I'm the second owner and the p/o had them installed. He said he had the head buffeting and the lowers completely cured that. With the snow here I haven't ridden in a while, and have yet to be on the open highway to see how I feel, but I think I'll be pleased.

    I have to admit that I'd be one of those guys that didn't realize to solve the buffeting issue I'd have to address the air flow that was coming UP from UNDER the windshield.

    I have to admit that I always thought it was the opposite. That is, it is the lack of air behind the windshield that produces a vortex that can be minimised by encouraging air to come up from below the windshield. Tilting the windshield back allowing air to flow under actually improves the situation.

    Personally, I think all windshields are evil, and the MG flyscreen is the largest screen I ever want to use.

    What Clayton said...
    in point of fact they are so effective that I remove them to ride in the summer. Yes, the buffeting increases but so does the flow of cooling air to the rider....

    They certainly do work. Big difference is they block out the airflow onto the chest area during cold weather riding but also should be off for hot weather riding. I made my own set, as I was reluctant to pay $250.00 (au dollars) for some thing that may not work. They do stop the head buffeting.

    Total agreement, they do make a significant difference in the head buffeting.
    I also noticed in your photo that the brackets for your deflectors appear to be chrome. Mine are painted black. Was that an option that I overlooked when I ordered mine?

    Thanks,

    Dave

    CaliVic made is out of stainless. I think this guy could make anything, I'm so jealous. You ought to see the trailer hitch he made.

    I just installed these and they solved the buffeting problem (which was really bad) by 80%. Big win for $120...........

    Also send a nice stream of air around the chest and shoulders from underneath, a welcome relief in the summer. very high value upgrade.

    Have just fitted the Guzzi screen lowers.
    They have made a big difference.
    I am 5' 9" with inside leg of 31"

    Initially I fitted the lower deflectors and found a significant improvement. I have since fitted a Laminar Lip, parallel with the top of the Touring screen and would say for me (5' 10" and inside leg 31") the buffeting has all but been eliminated although there has been an increase in wind noise since fitting the Laminar Lip.

    I put them on recently and am the same size as Robert. They did decrease buffeting, no doubt. I think they are worth the $$ even if they are a little pricey. It is quite noticable at much higher speeds where the buffet was tending to move the handle bars a little back and forth. (105 mph).
