So what is the right amount of wind to have on the rider?

Too quiet may make you feel like you're in a cage.

Too much and it causes noise and neck fatigue.

What say you???

It turns out that the solution was to separate the windshield from the bike allowing air to flow under it, thereby relieving the vacuum that is created behind it which dumps turbulence on your head. We patented an adjustable bracket system which does this and simultaneously allows you to control the angle and height of the shield so you can dial in the smoothest possible airflow. Now you can look over the shield, not through it, and keep your visor open even at highway speeds with quiet calm comfort and a great view of the road. Now THAT's what motorcycle riding is all about!

So using one of these, how quiet do you want your ride?

One consideration is that as wind noise decreases, engine noise increases.

However, the absence of any buffeting with some wind noise and the right amount of engine roar might do the trick.

So how much of each, if any, do riders need to be comfortable yet still feel like they are riding?

I added this for $20 and very happy with it.
So do you need ear plugs with the addition on and properly adjusted?

And is wind noise and buffeting reduced enough to prevent fatigue for a series of 8 hour days?

On my K12RS with a customized, high windscreen, I don't need ear plugs up to 40 mph. At 40 mph and below you can ride all day, no problem.

Above 40 mph, engine noise comes up and is reflected off the back of the shield such that it is too loud for riding more than 30 minutes at speed without earplugs.

Also, would you use a screen that totally eliminated wind and noise???

Alright, I'll bite.

I grew up riding bikes with no windscreen at all, and I like it like that. I live in Southern California where you can do that all year round. The K1200GT is my first bike with a windscreen.

In the summer, I use the stock BMW windscreen, most often in its lowest position. I have a spare new one still in the box, and think about cutting my old one short, like a "sport windscreen."

In the winter and for long trips in unpredictable weather, I have a tall Aeroflow AeroScreen windscreen. I also have their side wings, called AeroGards. Highly recommended!

The K12RS without any windscreen is pretty quiet.

Just looks odd.

And you get a lot of air on you at speed.

My current screen is higher than the BMW comfort screen and I can look over it.

With my helmet shield partially lowered, I get plenty of ventilation but no gnats crawling around my ears.

And no bees or stones in the face.

Also a double windscreen like Madstad. The leading shield is open at the bottom allowing air to come up above the shorter trailing shield and prevent the development of negative air pressure behind the trailing shield and resultant buffeting.

Some OEM bikes are using the same principle with the instrument cluster cowling acting as the trailing/shorter shield.

Well, it depends on all kinds of factors, such as size of rider, size of windshield, seating position, height, handlebar position, custom seat, tail or head wind speed, etc.

MY experience has been on a couple of unfaired bikes, then a Kawasaki 900 with Windjammer fairing, then an R90s, then two R100RS's, then two K100RS's, and now a K1300s.

What I've found is in each case except the Windjammer, there is a certain wind speed that balances the rider's lean forward such that there is a minimum blast of air against the rider, but most/all of the weight on the hands is eliminated. Faster and you're hanging on against the wind, or hunkering down a bit to raise the 'balance speed'.

On an unfaired bike, that seems to be around 65mph. On my R90s, with minimal fairing, it was about the same -65-70mph was the most comfortable.

On the RS models, all of them (and the K1300s) have wind hitting me just around the armpit level so my shoulders and head are in the wind. I like a windflow that puts the turbulence below my helmet, so it is getting smooth air hitting it. I've got a fairly long torso at 6'2" (only 33" inseam), so if I have good posture, my head is in the smoother, quieter air. With the lean angle of the R100RS, the balance speed was up around 75mph, and there was a nice smooth engine RPM in that range as well.

With the K100RS, the balance speed was about around 75-80. With the K1300s and it's smaller windscreen, the most comfortable speed is definitely 85mph with no wind.

What really kills me in the K1300s is riding at 45mph in traffic. Especially ater a few hundred miles have turned my wrists into sore points.

Been riding my '02 K12RS the past few weeks with the windscreen removed (no windscreen at all).

Very smooth airflow when leaning forward at the optimal angle at 60 mph or above.

Other than the front end looking bonky, this works well for me.

I'm 5' 10" and wear a full face Shoei helmet.

There is significant turbulence above 40 mph with either the sport or tall OEM screens and a laminar lip only make it worse.
