Gen 4 Edging Noise Turbulence Reduction

Gen-4 Edging™ kills noise, turbulence and road spray for a smoother, quieter and more enjoyable ride.  But reducing motorcycle wind noise and turbulence is more than just making the ride more enjoyable it is also about preventing hearing loss.  The edging does this by making Micro-Swirls™ which reduces capsule friction, turbulence and noise.  Installation is fast and easy making it an effective alternative to those ugly taller shields.  A great value and more effective than a bigger shield. Gen-4 can even be used on your next bike.  Eliminate helmet shake, wind-roar and bug/rain spray with one quick, easy to install product that adds a rich lustrous look of your bike.

The edging presses on making it the quickest easiest way to eliminate motorcycle wind noise and turbulence. Compatible with all 1/8″-1/4″ shield materials, will not fade, crack or lose rich luster. Please note: Beaded-edge shields can be difficult applications… See Victor Mudrack’s statement on the review tab and additional information on the FAQ tab.  Money-back guarantee details on Services – Policies page.

    Installed yesterday on my restored BMW R100S w/ low screen and dolphin fairing. Bike has slightly raised bars. Wind used to hit mid-helmet. With Gen-4 edging the buffeting has disappeared. Just clean air flow. Excellent results.

    • Chuck Saunders (verified owner)

      That is great news George. The dolphin fairing for R100S is so small getting such good results is amazing.
      Ride safe,

    I used Saeng edging on the Rifle fairing on my R65 & on my 650 V-Strom (custom Cal-Si shield). Initially, I thought it was ok, but nothing special. Then, after two weeks, took it off & went for a ride. Good grief… I cut the ride short so I could put it back on! Excellent product!

    The Gen 4 Micro swirl edging works perfectly on the Rifle windshield on my 87 Concours . I recently installed a much shorter shield and attached my existing piece . It puts the airflow right about where I need it .

      Thank you Jason… much appreciated. When one is careful the Edging will hold up bike after bike.

    Hi Chuck. I have done a couple of hundred miles with the edging now and all is good. I certainly don’t have any problem with turbulence that you said may be a problem with the flip-up screen. The edging has cured a peculiar trait of the Triumph 1200 Explorer screen as I thought it would and that’s why I made the purchase. The screen is ‘waisted’ about half-way up it’s length and, in heavy rain, a stream of water ran of the screen at the waisting point straight into my face! Your edging has prevented that and the rain now goes somewhere else, I know not where!
    Thanks for the edging and stay safe.

    The original piece I ordered was for my BMW. I was unhappy that it was
    “bridging” across the top from corner to corner, rather than holding tight to
    the concave dip atop the screen. Knowing what I know NOW, I would’ve left it
    hanging in the direct morning sun to soften-up BEFORE installing it. (what I just
    now did with this most recent piece for my Honda). So, I took it off.

    Then, a brainstorm. Although the TMAX has a fat beaded edge, damned if it
    didn’t snap right down onto that screen with the ball-peen hammer encouragement
    as you outline on the site. Works great! So, you MIGHT want to consider stating
    that it might, in fact, be compatible with some beaded edges. Just a thought….


    • Chuck Saunders (verified owner)

      These are great comments Vic. You are, at least to my knowledge, the first to successfully mount the edging over a beaded edge! We used to suggest hot soapy water for difficult applications but a little patience and good old sunlight just might work better.

      Take care, ride safe and stay well,

    Received my edging by mail very rapidly and fitted it soon after. I was pleasantly suprised how easy it was to fit, after some doubt about which way round was correct, and it looks good. It stays on too even at speed! It certainly works at reducing turbulence and is much less intrusive in vision than the alternative deflector I had fitted. I ride 20,000 miles a year and on-bike comfort is very important.

    The edging on the motorcycle eliminated the wind buffeting I used to get on the top of my helmet. In the rain, the water now doesn’t run up over the top edge and then down the inside of the windshield obscuring my vision. Likewise in the sidecar in the rain, the water doesn’t run up over the edge and drip down on to the seat and my wife’s lap. – T. Stueve, Gold Wing Road Riders*

    Edging has made my Buell S-2T tourable. It has raised the wind and bug line on my jacket from mid-chest to top of shoulders. A simple accessory for a lot of comfort at higher speeds. – B. Burns*

    Just rec’d the Stealth Edging and Night-Cutters™. Mounted them on my Valkyrie Tourer. Superb product, excellent results. I’m 6’6” and was going to have to purchase a taller windshield – not any longer. The stock Hondaline windshield is PERFECT with your edging!! The lights mounted without hassle on the Cobra light bar and really do the job. I ride safer at night because I can clearly view both sides of the roadway. Get comments on how well they look too! I couldn’t be more pleased. Thanks again for great service and superb products. – G. Gotzinger*

    I just returned from a 600 mile trip in the mountains of Arizona, and I must say, it was the quietest 600 miles I have put in since I have been riding motorcycles. Your Winglets and Stealth Edging WORK! It’s so great to hear the “whisper of the wind,” rather than the usual constant roar I’ve had to contend with all these years. – H., Arizona*

    I just recently added your edging and was pleasantly surprised at the results on my Honda ST1300. I can lower the electric windshield all the way down, get a little air to keep me cool, and yet there is no turbulence. It is eerie smooth. If I raise the windshield another inch, still well below my line of sight, virtually all noise goes away. I spent a whole lot more money on a _ _ windshield, but if I had known about your product before, I could have saved a lot of money. – D. Chance*

    Just wanted to thank you guys for an excellent product! I am a new rider and after trying the tall Wunderlich, (didn’t like looking through it,) then the short Wunderlich, (the wind was a bit much and I was beginning to feel like Goldilocks…), I discovered the microswirl edging. It made a huge difference helping to cut the wind on my trip from Fairbanks, AK to Helena, MT, to Bellingham WA, to Haines and Haines Junction, AK and then back home to Fairbanks. I have recommended it to several other riders. Thanks for a great product! – A. Huddy*

    The installation took about 5 minutes and a few whacks with a soft piece of wood. Once I was satisfied with the installation I trimmed off the bottom ends of the edging to match the contours of the windshield. Before the installation of the Micro-Swirl Edging the slipstream/wind-blast over the windshield was severe and the sound level was deafening, even with my helmet visor down. When I completed the installation I went for a test cruise with a maximum speed of 45 MPH. The slipstream seemed to have moved up a few inches and the velocity decreased significantly. Also, the noise level dropped an estimated 80 – 90%. My friend also took the bike out for a test ride and was amazed at the positive results. Your product works as advertised and my problem seems to be solved; I’m a happy customer. 2006 Royal Enfield – Bullet Classic 500 with the Classic Motor Works – Type 2 windshield.– C. Gullage*

    I just installed your Micro Swirl edging on a National Cycle aftermarket Windscreen for my 2009 Suzuki 1250 Bandit. It works fantastic! I’m a taller rider at 6 foot 2 inches and the windscreen, although better than the stock one, resulted in a lot of wind noise right at the front of my helmet. But your edging solved that problem. Now on shorter trips, like commuting, I no longer wear ear plugs. It’s made a huge difference in my riding comfort. It’s a great product! – J. Seals*

    I just wanted to tell you that you’ve got a great product. I recently added edging to the windshield on my Kawasaki. I immediately felt and enjoyed the reduction in buffeting while riding, but I was shocked to see that I’m getting five more mpg!!! Keep up the good work. – J. Bass*

    Chuck, It is doing exactly as intended. Quieter pocket of air than my BMW R1200ST or R1100RS.
    Very happy with product and Chuck’s expertise. Chuck could not have been more professional.

    I have been using SAENG edging for some 20 years on 3 different motorcycles. It allows me to run a smaller windshield and have complete wind protection at speed when I need it the most. It is a very effective air dam that is easy to install.

      Thanks very much Brian! It has been a real pleasure serving so many dedicated riders such as yourself.

      Ride safe,

  • (E) Can Micro-Swirl™| Edging be made from a clear material?

    The short answer is no. UV radiation cracks and discolors clear flexible materials and their elastomers damage poly-carbonate. Micro-Swirl™| Edging and trim is made from an aerospace material. Chemically compatible with all shields, its also UV, oil and solvent resistant and is not brittle even at 30 below zero… close to indestructible.

  • (D) How does Micro-Swirl™| Edging attach?

    Micro-Swirl™| Edging slips on and grips the windshield’s edge. It holds even around complex corners.

  • (C) What is a beaded edge shield?

    Beaded edges are found on “injection molded” shields. These shields are often more optically distorted and have thickened attachment points and a beaded edge. Most after market shields are thermal formed from a flat sheet. These shields are optically pure and have no thickened areas or edges.

  • (B) How do I determine length?

    Tape the shield-edge, remove tape, lay straight and measure, rounding up to the nearest foot or ½ foot. For best performance and aesthetics go end-to-end.

  • (A) How much edging do I need?

    How far around the shield depends on the rider. Most riders want to expand the height of the capsule and edging along the top does this however it it best to run the edging down the sides as far as possible. This extra coverage helps keep the capsule comfortable in cross winds and dryer while riding in the rain. Besides it also looks more finished. Tip: Never stop at a corner… for grip strength the edging needs at least 4 inches (10 cm) of relatively straight area when ending.
