Aerodynamic Screen [D1146ST]

Wind Cutting sound was very loud at Normal screen of 16 year NC 750X, so the price is reasonably cheap and it gets longer than NORMAL, so buy here we were able to expect windbreak performance.

As a result even if you exchange for GIVILong Screen "Wind Cutting Sound" There was no change at all.
The problem is that 50 ~ 60 km / H Highway 80-100 km / It is a thunder sound as if it is running with h, and on strong wind days this becomes even more severe. (Normal screen as well)
The reason is that the rectified wind from Screen becomes turbulent and hits Helmet. Since the width of Screen is almost Large in head suffering Helmet, we can not respond to turbulence especially from SIDE. When I stood on the test and ran, the person who stood quite quiet and laughed. so "Wind Cutting Sound" There is a problem with NC 750X concerning.

By the way, I think that the difference in Helmet is not big difference.
OGK I felt noisy with KAMUI I brought new to SHOEI GT - Air but it was somewhat quiet. Rather, because airtightness is too good, together with the way of turbulence hits, the change in air pressure in Helmet gets intensified, and Demerit comes out that it becomes easier to need the ear removal.
I think that I am 175 cm tall and very noisy, so it seems that people with the same height tend to think the same, but it is strange that I do not see such writings so much.
As I ride this way Stress will also accumulate and it may be hard of hearing if I go down, so I added my own Screen to both Screens SIDE at the expense of sacrifice of appearance. It is very bad Parenthesis, but I feel better than always feeling Stress.

Creating GIVIScreen is not particularly bad, but since turbulence occurs so far, I wanted you to expand the width. I also want a little more Length.
If I cut the Handlebar to a full extent it will definitely interfere, but it's not like I can not handle Handlebar Lock. However, I will apply it if I completely cut my eyes. I coped with Screen and dealt with it, but it was better that you cut more here. And from there I wanted the top to be wide.

"Windproof performance" As for NORMAL it will be much better.
The wind that was hitting around the chest and neck with NORMAL disappears and it will be around the forehead so I think that it will be much easier as the wind hits the body less. You can feel the benefit here.

Finally. "Windproof performance" Who wants to see it is better to be chosen as Length and looks.
"Wind Cutting Sound" Whatever you want to do, whatever Manufacturer's Screen you use "Wind Cutting Sound" I think that there is no big difference, so it seems better to do it by somehow widening the width or discarding the windproof performance and take the drastic cut off Screen or make it a pole Short Screen. (Maybe the latter may be better for midsummer)

NC750X attached to 16 years
After mounting I tested it but everyone says it "Wind noise" It is certainly annoying!
However, the wind that hit Helmet drastically decreased. It does not hurt when lightly lying down.
One problem.
Large type Universal Knuckle Guard hits Screen and can not fully lock.
Currently removing Knuckle guard and being processed
