This windshield is great, I am 6'2" and I can see over the top of the windshield and it pushes the wind off my chest and over my helmet. This makes a huge difference on longer rides as you don't feel so beat up by the wind.
Very good quality and fairly easy installation on my 2002 Honda VT1100C. I am 5' 8'' and there is some slight wind buffetting around my helmet. I put my hand above my head and the wind is going over my head. I wear a full face helmet and when I open my visor, I don't hear the buffetting. I originally tried the 15" shield and then swapped it for the 17" shield. The 17" shield did have less wind buffetting. Overall, I think I will enjoy this purchase. I installed it with the trigger lock mounting hardware, so it is just a 30 second or less mount or dismount of the windshield.
I own a 2011 harley iron and this was the perfect finishing touch. I am 6' 2"; speeds up to 55 had little to no wind noise. above 55 you will start to get alot of wind noise. overall i am pleased with the product and with the quick connect matched up with it makes for alot of windscreen adjustment angles. Highly recommend.
