I have a Yamaha Majesty with a Givi windshield that I had gotten used to. Since I bought it used with the Givi I had no way to compare it with a stock Majesty windshield. Then I bought my Burgman. It too was used, but came with a stock windshield and I soon hated it. Compared to riding my Majesty with the Givi riding the Burgman was terrible. The wind noise was deafening and the buffeting to my head and my shoulders was terrible. The windshield flexed from side to side which only increased those effects. In a crosswind the windshield acted as a sail and tried to drag the bike all over. Even with the hand guards the wind tried to go up my sleeves. Did I mention the buffeting? At 30 MPH I couldn't hear the engine; at 60 MPH I could barely think the wind was howling so much.
Thanks to Daboo (Chris) and his sacrifice
in testing the Givi Airflow (AF266 for the AN400), along with the others who also took a chance and posted the results, I though that maybe the Airflow would be my solution, too. So, I did some more research away from this board and found some BMW riders who also liked the Airflow along with some other information. Then I took the plunge and ordered one for myself. Some more research followed that included finding three You Tube videos on installing it. Last Thursday I removed the hand guards and the stock windshield and got everything ready. Here are the You Tube videos:

On Friday I installed the Airflow with the usual problems, for me, including dropping a bolt on the floor and not being able to find it until I moved the bike and needing at least one more hand at various times. Note that the instructions are a little vague. For tools I used a 3mm and a 4mm hex wrench, a 10mm box end wrench and a Philips #2 screwdriver. As per the videos I installed the brackets via the upper windshield holes first using a spring clamp to hold everything together. A little soap and water mix on the rubber gasket makes it easier to insert. Tighten snugly; do not apply great force.
There are three holes on each side for mounting windshields. Each hole has a rubber plug in it. Those plugs have a nut inside at the end that the bolts screw into. When the bolts are tightened the rubber is compressed and expands out to hold everything in place. They also help to absorb vibration. On the bottom hole on each side the rubber plug goes through the Givi windshield just like it did on the stock windshield. The stock bolts and washers are also used on these. For the upper two holes on each side the rubber plugs go in first with the bracket on top. The metal spacers fit into the holes of the brackets with the windshield on top of the bracket. Then the washer is put on top and bolt inserted through and tightened snugly, but not too tight. Again, a little soap and water mix on the rubber plugs makes them easier to insert and it soon dries out leaving everything good to go. However, be very, very careful putting the rubber plugs in as they have a tendency to suddenly shoot through all the holes and wind up somewhere inside the front of your Burgman, lost until you can dig them out.
After I got done installing the Airflow, and the body panels were back on, I naturally had to take the Burgman for a test spin. On Saturday I did some more testing. The results were that I could have been on a different bike! With the upper screen in its lowest position I could hear my engine at 30 MPH. When I found my personal upper screen sweet spot, about an inch below the maximum height, I could hear the engine at 60 MPH, the fastest I've gone so far since the install! The wind noise and the buffeting were all but gone, too; just some gentle reminders on mu shoulders that I was pushing air around. I found some light crosswinds, but they did nothing to the bike. I could feel them hit my body, but there was no longer the sail effect the stock windshield created and the bike remained stable. Wind deflection around my hands was better than with the hand guards; the air stream was both higher and further out to the sides, no longer tried to get up my sleeves. The Burgman grin is back!
Oh, don't try to move the upper screen to its top position while going down the road at 40 MPH; unpleasant things can happen.
