Most of us agree, and complain that the windscreen on the GT, wether high or low model, gives a lot of turbulence and noise. My experience was very strange. I wear glasses under my helmet. When it rains, the Pinlock visor on my Shoei XR 1000 remains clear, but my spectacles fog up badly. I found that out on my Croatia trip, while riding with my high shield in the uppermost position under incredible rains.
However, when I put the shield in the lowest position, I had air around my helmet and my glasses were clearing up. So, the high shield DOES function aerodynamically, but it still gives turbulence and noise. Can any of you confirm my experience ? Can someone give an explanation ?
