One of the biggest issues I've had with my new motorcycling experience has been the wind noise.  It's been really really loud - even at moderate speeds like 30mph.  The wind just whips off the windscreen and straight to my head.  Here is a photo of the windscreen.

You can see it just barely extends higher than the handlebars.  It does deflect some of the wind but a lot of it is deflected into my face.  Not so good.  Thus, yesterday I installed a new Givi D260ST Windscreen.   Here is it from the same profile view:

As you can see this one is much much taller. I got to ride with it for the first time this morning and the ride was much quieter.

I was a little concerned about putting such a tall shield on though - in the warmer months I like having some wind hit my torso - it's precisely why I wear a mesh jacket - yet I didn't want to have to switch between the screens based on season if I could help it.  My concerns were unfounded though.  I still get plenty of air( but not too much) passing through the jacket while I'm moving.

So far I'm happy with the upgrade. Plus it was the easiest thing I have ever installed.  Remove six total screws to take off the old screen, add the six screws back to put on the new one.  If you have a bike and are concerned with buffeting and wind noise adding an improved shield is a no-brainer.
