National Cycle Street Shield EX Disconnect

[deltamark]

Thanks everyone for the input. Lowering and changing the alignment of the fork clamps and minimizing the angles of the connecting bars seemed to do the trick. The windscreen now sits closer to the headlight, looks perfectly symmetrical and was completely stable at 70 - 75 mph.

After my 30-mile commute home, I'm really not sure this is the right windscreen for me, though. I'm just over 5' 10" and the wind is minimized on my torso, but substantially noisier at helmet level. I have to bend forward and down to get into calm air and that isn't something I want to do for any length of time. I notice that when I stand on the pegs the clean air is much quieter than when I am in my normal upright sitting position.

I've read a lot of the windscreen threads on this forum and get the impression that it is tough finding an ideal solution. I may try something else as I'd like to have something to help reduce wind fatigue on longer trips and am open to any suggestions. Thanks!

I had the same problem with my attempt touse the Street Shield. I wound up just going naked, but others had luck with adding a deflector shield to the top. Good luck.

Back in 2013 when there was a lot of experimenting going on with this new bike, we discovered the the best height for a windshield that protected the body but didn't cause turbulence or buffeting was either 10 1/2" or 22" above the ignition.

Forum member CIP was the first one to cut down a NC Street Shield EX and I followed his lead. You may want to try cutting yours down a bit before buying something else.

The Dart and Dart Marlins basically do the same thing which is why they are so popular.

Here's mine NC Street Shield EX cut down 5 1/2" iirc

Thanks EmptySea. I thought about a deflector. I'd be curious to find out which one other riders have had success with.

Thanks again Ferret. I would definitely try the cut-down, but am not exactly confident about being able to do that cleanly. If I don't hear from anyone about a deflector that's worked for them, I may give it a go since the screen doesn't really work for me as is anyway.

IMHO there is no perfect shield that makes all bikers happy.
But I am happy with my NC Street Shield EX.
For noise, I always use ear plugs. There is some turbulence or buffeting around my head at higher speed but for me is acceptable.
I am also considering adding Wunderlich Vario-Ergo extension . These are available in clear and smoke:

Good luck with your choice or modification Mark..any shield for Rudi???

[deltamark]

Hey Peter,

Thanks for the recommendation! I always use ear plugs, but they don't help enough at speed with the EX shield. I am finding that a few other riders have had success with the MRA extension and am considering that too. If you add the Wunderlich, let me know how it goes.

I added a sidecar windscreen for Rudi, but he hasn't yet said anything about its effectiveness. ; )

Judging by his behavior, I'm suspecting that Rudi may be experiencing turbulence issues, though. He seems to lie down more quickly now, possibly to escape increased wind blast. I may either have to remove it and see if he behaves differently, or get someone to drive the rig with me in the hack so I can experience it.

My DLX came with a National Cycle screen and an MRA deflector. Not only did they create unnecessary buffeting, they looked dorky. They both ended up in the trash after my first ride.

Your results will be different, but in my experience, if you want a quiet ride, either eliminate the screen altogether and go naked, or find a bike with a touring-length windscreen (Gold Wing, RT, etc.), ideally electronically adjustable. Anything halfway will only cause buffeting. Again, my experience and opinion only. I sincerely hope your results are different.

Hey LongRanger,

I appreciate your input on the NC screen and MRA deflector. Yeah, I think that combo doesn't quite match the cool aesthetics of the CB, but I'd be willing to sacrifice that if it worked, at least while on road trips.

I realize that windscreens are a crap shoot. I think I went through 4 screens on my Tiger 800 XC before finally finding one (with a deflector) that I could tolerate. And I know I'm spoiled by the electronically adjustable screen on my RT. I don't expect that type of protection. Just something to reduce wind fatigue and maybe even weather exposure on 200 - 400 mile day.

The search continues!

In reading these threads I realize that I have been very lucky in the windshield department. I have two shields for each of my CBs, both from NC (to share mounting hardware).

The small NC Deflector works best for hot summer temps. I angle them so that the turbulent wind blast arrives just below my chin at highway speed, which avoids noise and buffeting issues.

For winter riding and long road trips, I use the larger Plexistar 2, which offers much better coverage (think hail storms and swarms of bees) and sends the turbulent area to the top of my helmet. This also avoids noise and buffeting around the helmet area.

For both types of shields, I did spend some time adjusting angles and testing to make sure the turbulent area was either above or below the face shield. That seems to take care of the worst buffeting and noise.

Maybe some pics of how its mounted?

Ah yes, pics would help!

After looking at it more closely, it seems that the brackets may not be aligned properly. The lower mount attachments are situated at the top of the forks. I tried to get the upper handlebar mounting brackets as similarly aligned as possible, but there is a slight variation due to cabling.

I think you can see from these pics that the ball-end connector is coming in at an angle. I'm guessing I need to remedy that.

Yeah MAN! I've the same sheild . Try mounting the lower brackets lower.
It's not gonna lean way back, but itll work.
My install has worked well for 3 plus years. Just a little shimmy at 70 plus.
