No replies to my message about cutting down the windshield. I'd recommend trying the B windshield first. The Valkyrie windshield was more vertical than the B or T's windshields and thus it seemed easier to determine a satisfactory cut. Good luck.

Absolutely... Go with the stock Model B windshield, or perhaps the wind deflector windshield; I'm 5' 9" and have zero wind issues, I also keep in mind that I'm on a motorcycle and not in an enclosed vehicle...

Wind is a thing that comes with riding... I have found different comfort levels with the use of the fairing wind deflectors in the OPEN vs CLOSED position, as well as the recent addition of the lower Leg wind protection - especially in the colder Fall season.

All of these things allow me some degree of adjustability based on ride speed and ambient temperature.

I think the idea of cutting down the stock windshield is a bad move; in the end, the windshield will look ghetto...

These things are really tough to optimize, unless you have a wind tunnel simulator and the experience to try different shapes and observe the affects of those changes...
 
I have a 'B' also, and have tried many screens.
The stock screen sucked.
I then bought a 7Jurock 20" screen. It was HUGE. You could roll a cigarette behind this thing....
I then bought a 7Jurock 18" screen. Obviously it was smaller, but not small enough. the top of the screen was right in the centre of my vision. Annoying.
I then tried a TC screen made from Chinesium. No good, as I had to look through the screen, not over it. I didn't like that.
Lastly I bought the Klockwerks screen. It is the best of the rest for me. It cut down 80% of the buffeting, along with the winglets.

I had the full height windshield on my HD Fatboy cut down and it worked brilliantly, can take off an inch at a time and test. Mine ended up half the original height and was brilliant yet low. The stock screen on my current R8B though is hopeless and that's why I'm trawling these posts

What's the wind deflector windshield? I'm a tiny bit taller than you and get hammered right in the face with the stock screen.
 
The Wind Deflector is pictured below on the new 2025 Model B; it's much shorter or almost non-existent when compared to the stock Windshield. The idea is that it provides "clean" air flow, vs turbulent air flow:

In my 6 BMW bike experience I've never struck a dud in terms of their wind handling skills - until this one. The wind noise is deafening from hitting me right smack in the face and in conjunction with the front tyre roar an aural disaster, even though the Shoei is a hinged open face type its very late model and normally quite quiet. On the GS I could ride most of the time with my visor open.

The two best wind protection bikes available today are the BMW Transcontinental and the Harley Davidson Road Glide.
I’ve owned both.
I did not look over the windshield on the TR, but with winglets in the out position and those lowers in place, I had nearly zero wind riding.

I just ordered a set from Japan, not BMW ones, and will see how they perform. Cheap enough for me to toss in the bin if they are crap. I have the standard B windshield and I use a Roof Boxer 8 helmet, which is always on the open position unless I get caught in the rain. To be honest, it works for me. Yes, there is air turbulence but not too bad or at least I got used to it. The wingless should address the turbulence coming from the gap between the lower part of the fairing and the upper part of the fuel tank.
This is my first bike with some sort of wind protection, hence I am probably used to being hit in the face and chest from air rushing towards me.
 
My Model B certainly has adopted the TC Wind Management attributes; where I installed the Fairing Winglets and the Lower Leg Wind Protection pieces.

I absolutely use the adjustability of the Fairing Winglets; at slow speed (< 50 mph) and Summer weather, I keep them OPEN in order to provide wind flow..

I wear a 2/3 helmet... I'll wear a full face helmet from my GS Adventure days during these crazy Winter rides that we do, once or twice a year...

I keep thinking about the TC lowers for my B, but the cost is likely more than I care to swallow right now.

Yeah.. I bought the Model B already knowing that I was going to slightly adopt the TC attributes; I bought the Model B vs the TC, knowing I didn't need or want the thicker seat, rear luggage case (wife doesn't ride) and I didn't like the TC gray color (Wheels, front shocks, dashboard, handlebars, Engine Covers, etc.) - so I went with the black gloss color Model B.

Finished Product: a chunky Model B

You could mount the $95 lowers on your bike like some of us have on our R18’s. Make a world of difference stopping updraft.

I’ve got the bmw winglets on. I shaved them down to clear the signals. Honestly, not a huge difference maker for me. I wonder if it’s because I’m super tall and the wind isn’t really at my face.

What’s the $95 thing? Got a link?
 
Here you go BigJim.

Memphis shades lowers.
The part number for the deflectors is MEM5804
The part number for the mounting brackets is MEK1980

The mounting brackets very with bike so here is the URL for it:
https://memphisshades.com/products/fork-deflectors-yamaha-xv1900-roadliner
This particular one is for the Yamaha Roadliner but it fits my R18 perfectly. Best mod I ever did. Zero updraft now.

As an experiment on what it would take I found if I slip four fingers one knuckle high above the screen the buffeting stops instantly and would be totally satisfactory. Then I could really hear the roar of the front tyre when riding on chipseal surface which is nearly all roads in New Zealand. I thought the original tyre on the R1250GS was bad but its nothing compared to this Michelin.

I've noticed that most people that have buffing issues seem to be like 5'6"ish. I am 6'4" end it is absolutely horrible driving with a short windshield. I just bought a used OE wind deflector off of eBay so we'll give that a try. I do have the winglets by the turn signals and really didn't notice much of the difference but I haven't had a chance to ride it very much since November since it's been winter time here in Indiana.

I'm 5' 9" and didn't have any real complaints"buffeting" wise on my Model B; however, I did sort-of convert my Model B to take on the TC attributes from a Lower Leg Wind Protection and Fairing Winglets.(I knew this would happen while looking at the bike on the showroom floor). I also added the Auxiliary Lights and Directionals in the same manner as the TC; however, wind buffeting wasn't the driving force - I wanted comfort options when riding long distances.

I do adjust the Fairing Winglets depending on weather temperature and riding speed in order to manage the effects of the apparent wind; for instance, Winglets are OPEN at speeds below 50 - 55 mph and CLOSED at higher speeds... I absolutely feel a difference between the two states, and that is exactly what I wanted - choice to make me comfortable...

I sometimes think that folks are comparing the effects of the wind on their motorcycle vs driving in their car...

Agreed.. some bikes management it better than others.. but it comes with the hobby of riding...
