I purchased the 15" windscreen for my '05 Concours. Installation was a snap ... it took me longer to get the stock windscreen off than it did to install the new one.
For reference, I'm 5'8" with a 30" inseam. With the Rifle windscreen installed, I was still able to see over the top. However, I noticed a HUGE improvement in wind buffeting. Before, with the stock screen, the wind hit me right across the top of the helmet, pushing my head slightly back ... sore neck at the end of the day. With the Rifle screen, NO buffeting on the helmet. I can also hear the audio in my headset much better now.
The only remaining issue to see is how things are once the temperature goes up. As stated, there is much less airflow going up over the windscreen, although I do still notice a little sneaking around the sides. Hopefully that will be enough ventilation once summer gets here.
