Three years ago I installed a Givi A172 windscreen to the 2013 Suzuki SFV650. It deflected a little bit of air, but was more cosmetic than functional. I have continued to look at options for more wind protection and decided to try the windscreen from Powerbronze called the Light Screen.
The two products have very different mounting techniques. The Givi uses the two existing bolts that hold the instrument cluster. These are in a very tight spot and make it a pain to add or remove the screen quickly. The Powerbronze adds brackets that utilizing the existing bolts at the top of each fork leg and the side of the headlight. The screen can then be added or removed easily while keeping the brackets in place. The Powerbronze also offers some vertical adjustability to the position of the screen.

The screen than has some rubber grommets and metal spacers added to the screen before it is bolted to the brackets.
And bolted to the brackets which is not easiest to see since the screen selected is Light Tint. It is shown in the lowest position. After a couple of rides I did end up sliding it to the higher position.
Here are some comparison shots of the two windscreens.
Overall, the Powerbronze windscreen does a better job of deflecting the wind while the light tint does not make the screen stand out from the appearance of the bike.
