Any tricks for more rider/passenger air flow?

Early in my LT adventures I was trying to protect us from excessive air flow and was very happy when I came up with a second-hand screen from a member here. It became my go-to cold weather screen.

But, now that it is getting hot, I changed back to my low/Euro cut screen for the summer. At 92 degrees we still don't get much air flow. We use the cooling layers, vented gear, etc., but without good flow it doesn't do a lot and that same shelter we love in cold weather we now don't appreciate in the hot.

I tried searching, but three-letter terms don't get handled by the search function. Was just wondering if there were little tricks to get controlled air flow to rider and passenger on the K1200LT.

Thanks in advance!

Don't forget that the winglets below the mirrors will pivot and provide more airflow on the legs/knees...

I "close" them when cold, "open" when hot. If you go in-between does it generate more turbulence or is it more binary (on / off)? Might have to play with this some today after work (sounds like a good excuse for a ride.)

Re: Any tricks for more rider/passenger air flow?

I now have a cut down to 14 inch windshield and I get a lot more air plus all the way up I can see over it like stock all the way down, now I use the electrical adjustment feature to put it where ever suits the moment, will probably put the VStream back on in the fall when it gets cold

That is why I say bring back the bell bottom jeans, great for funneling air to the naughty parts.

Re: Any tricks for more rider/passenger air flow?

A couple of years ago I changed out the scratched up OEM windshield to a Cee Bailey -2 reverse curve one that I love, as I look over it in the down position (99% of the time). But this got me thinking to take out the old shield and cut it down about 6" to use as a summer shield.

Re: Any tricks for more rider/passenger air flow?

I actually did go looking for little vents that could be applied. Kinda similar to what I had on my Goldwing twenty-some years ago.

My summer shield is as mentioned is the actual BMW short shield with the Euro cut. Much more flow than my Cee Baileys (which I put a Euro cut into) or my stock full size. When I lift it up to the right height, it does seem to allow a little flow to come in below too.

I know on some bikes there are little things to add here and there to bring more air in. Was hoping there was something figured out like that for the LT.

Re: Any tricks for more rider/passenger air flow?

I did fit a vent from Honda Goldwing.
It looks good but does not make a big difference when the weather is very hot.
I think the best solution is to fit the smallest widscreen and use light vented gear.
I ride in tee shirt and jeans (I know I should not)

Actually, I just did a little forestry road riding on my R1100GS for my lunch hour. *Much* more air flow, much more butt hurt

Re: Any tricks for more rider/passenger air flow?

Good on you!

Wish I could have gotten out today, but weeds in the garden had my attention.

Maybe chop the W/S down an inch or two?

I've got a New OEM BMW standard w/s for sale as of today, never had a bug hit it. Send me a PM for details and pics.

As Esso used say, "Happy Motoring"!

Re: Any tricks for more rider/passenger air flow?

well you could remove the screen and winglets all together that's what I would do.

Well not really, it is a difficult balance, shortest screen fitted and winglets in, I also use a beadrider in summer great for keeping bum and crotch cooler this alone helps me keep cooler all over.

Re: Any tricks for more rider/passenger air flow?

Cutting down an old shield got me thinking. Has anyone cut slots or drilled holes in the lower part of a cut down shield? I recall the old GW I had had a flow through vent in the screen. This would allow the flow without adding too much buffeting to the passenger.

Yesterday it was 96 on the way home from work.

The problem is the opening at the bottom of the screen which send air up the inside of the screen to meet with the air from the outside to provide smoother flow over helmet, believe that is purpose, on my K100 I modified the screen to be like the LT for that reason. Air from any opening above that opening will just get added to the upward flow of air on the inside.

Last time I did that pair of bootcut jeans had a hornet make it all the way to the naughty parts. Needless to say the motorcycle was off and the kickstand was down before I stopped glad it did not fall over. I wonder what the people riding by thought as i dropped my jeans on the side of I64

The LT windshield does not seal tight at the bottom like the Wing, but rather has a built-in air gap to allow air to flow through to help with pressure management behind the shield. I suspect that gap flows more air than the Wing vent ever could.

Probably the only solution is something like the Baker-Built air wings made for the GW. I don't know if something like that can be adapted to the LT. The 1600 has something like this built right in and they work fairly nicely.
