I've researched a bunch of threads here and can't seem to find a definitive answer for a tall windshield on the K75s. I'm 6'1 and I get bashed in the face by the wind, but can't get down low enough to really mitigate it. I won't be selling this and getting an RT, as it belonged to an Uncle and is sentimental.
I want to get the Gustafsson 19in windshield in stock width. What's the general consensus on them?

After a bunch of experimentation what I found to be the best solution was to get an old stock windshield and cut it down about 4 inches. That put the turbulence down on my chest greatly reducing the noise and buffeting on my helmet because it was now in a clean airstream. I also had a K75RT with the same problem, and I did the same thing cutting it's shield down which not only reduced the buffeting but also made the bike a little bit cooler to ride in hot weather.

I would try a strap-ons laminar lip first, on the existing screen.
K75 mounting plastic expanding plugs are wear items that'll fling a tall windscreen into your lap.

Gryphon, I have two stock windshields so I can cut one down and try that out. Side note - which auxiliary lights did you install on the front of your bike?
In the meantime, I’ll look into those nylon license plate nuts recommended.
Thanks for the help so far everyone!

Aeroflow is the way to go if you want the best wind protection on a K75S. (I'm 6-2 and still prefer the stock windscreen.

Some readers might get the impression it's as simple as using a guillotine.

What’s occupying their space is an Orkin pest control
There’s no Aeroflow signage anywhere on the building nor any we moved to another location sign
I think it’s safe to assume that at this time there’s no more Aeroflow.

I won't be selling this and getting an RT, as it belonged to an Uncle and is sentimental.
Another option is to buy just the top part of an RT fairing. I've seen an RT converted to a naked but the front piece was kept. Your brick could be easily converted back to original. The dotted part was cut out. I took a photo of it but probably won't be able to find it back.
In my avatar is another option, I wanted a higher screen than you can buy so I used heat to bend a piece of polycarb and cut it to shape with a jigsaw, then filed it for a neater finish.

Looks like there is a 20W version now with a little bit different housing.

As far as cutting the windshield, I covered it with blue masking tape, front and back and marked where I wanted to cut it. I cut it with a jig saw using a plastic cutting blade. Hold the windshield securely and go slow.
After the cut, I cleaned up the edge with a file followed by wet sanding with finer grades of sandpaper on wood blocks starting with 100 grit going down to180, 220, 320, and 400. Keep going with finer grades until you get the finish you like. Avoid sanding on the front or back surfaces. Just work at rounding the cut edge to avoid scratching the windshield. Taping where you don't want scratches to protect the surface is a good idea. Take your time.

I hooked up with a guy in VA who recently bought an S screen from Gustafson. It didn't fit well on the S fairing. He's into 3-D printing so he scanned the S nose, 3-D printed one and then sent it to Gustafson so they would make him an S screen that actually fit.

However, I think the tall windshield will definitely do what I'm looking for - looks-wise and wind-wise. Can someone recommend the license plate fasteners recommended before to lock in the taller windscreen? Or should I just use arms to support?
Thanks y'all!

If you get it right, it will actually look better than the original screen, more like the classic bikini fairing/shields of the 60's. Get you that cafe look without hacking off the rear loop.

I used my dremel to trim a little more off, and sand the edges best I could. It looks decent! Let me know how you would recommend sanding the edges to make them a bit cleaner :)
Post by: The Mighty Gryphon on March 27, 2025, 02:50:53 PM
Start with a coarse file if you have one. Use it to do a rough rounding of the edge.
Then 80 or 100 grit sand paper wrapped around a small block of wood to shape and smooth a little more. Then 120 to smooth it some more followed by 180 and finally 220 to put a bit of a polish on the edge. Keep going finer until you like the way it looks.
