For me a windshield can make or break a bike.
I have had a lot of different bikes over the years.
I have hard bikes that have had
1.front head buffeting, and Lots of wind noise, that can tire you out fairly quick into a ride.
2. Rear buffeting, front was somewhat clear of buffeting, but you would get a weird rear buffeting that would push/punch you in the back of the head/helmet and upper shoulders. that would be very tiring quick.
When you ride a bike that the shield Provides positive pressure and is adjustable in height and Tilt
you can dial out all the negatives.
Set the angle at somewhere near 55 to 60 degrees of tilt, (there is a angle guage that comes in the instructions to get you close for starters) then adjust the height, so that the blast of air goes just over the top of your helmet and is smooth.
You can see it on their site.
No more swirling dirty air right in front of the face shield on your helmet breathing in all that dirty air, you get clean, smooth, quiet air.
It is a different riding experience.
Smooth out the air and make the ride very quiet, it lets you be able to ride much more comfortable for a much longer ride and you end up feeling energetic when you reach you destination, instead of completely beat up and tired cause you have been beat to pieces, during the ride.
They even have the Madstad shield for the F6B, and all the Goldwings, and many other bikes.
I have one on my NC700X and My Burgman 650, currently, but i had a Madstad shield system on my Vstrom 1000, and a 86' goldwing also, it made both of those bikes very nice to ride.
Like I say I have several of their shield i wont buy anything else, they are that good.
For me like the benefit of being able to look over the shield as i always watch for gravel, nails, and debree in the road while I ride.
