OK, after everything I said, I went out an bought a GIVI Windshield.
First impression is that the quality of the shield seems nice, and it is very clear.
But I do have a few gripes:
Why does it have weatherstriping around the edges? Couldn't they have just polished the edges like the other manufacturers? It looks nice, but I think the Sun will eventually separate this material from the windshield. It is also somewhat distracting while riding (as you see the rubber edge vibrating in the wind), but I'm assuming this is something you will get used to over time.
Instructions say not to leave the shield in the direct sunlight, as it will cause the shield to have a "lens effect" after awhile. I'm assuming this means that if you are looking through the shield, objects will appear closer than they really are? OK, so I'm wondering if GIVI understands that this windshield will be used on a motorcycle. As a result of being mounted to a motorcycle, it WILL often be in the sun.
Another warning sticker stating to only use warm water and a soft rag to clean. So Windex or any other window cleaning solution can't be used? Sheeze!
Set on high - Mild buffeting on the back of my helmet at 45mph, but that was the only test I performed before moving the suzuki windshield bracket back to the low setting. The problem I had was that the edge of the shield (rubber strip, and all) went right across my line of site. Too distracting to be safe.
Set on low - I could hear windnoise and felt the wind rushing across the top of my helmet, but it was signifcantly quieter than with the stock shield. Buffeting would occur occasionally, but nothing that would be annoying. This is the setting I will leave the shield at, as it is the only one that will work for me.
Improvements? - Overall this shield is an improvement over the stock screen. I hope it holds up for long hauls as I plan to attend the 125th anniversary of the OK Corral shootout at Tombstone in a few weeks. This will be around 550 to 600mi trip one way. I'm wondering if that Madstad bracket would be worth purchasing prior to going on this trip? Hmmm.
