SAENG Micro-Swirl Edging

Actually, I am using the SAENG Micro-Swirl edging with good results. It is designed a bit differently than the older "Stealth Edging" which I had tried last year, and it does seem to work better.

Here is the thing. If your windscreen, whether stock or aftermarket, is close to tall enough - but not quite doing the job in suppressing buffeting and wind noise, this stuff does help. That was my situation. It seems to be increasing the wind protection envelope by about two inches on the Clearview screen I am using - and it softens the stream of air coming off of the screen. I still look well over the top of this windscreen, but helmet buffeting is gone, and wind noise has been reduced to an acceptable level. I'm happy with what the edging is doing for me.

If you need a windscreen that is 3 inches or more taller - buy a taller windscreen. In that situation, this product will NOT make you happy. But if the wind is hitting at the top of your helmet visor already, and you need it lifted and smoothed out a bit more, this product can do that.

I also found that by shimming the upper screen mounts on my 650 out about 1/4", it makes this stuff work even better. (Doing the same shim job without the edging didn't appear to make much difference.) But the angle that the wind contacts the edging does seem to affect its performance, so tilting the windscreen slightly more upright can help.

Thanks pauljo. This may work for me then because the stock windshield is about right for me. Just need to disperse the wind a little more. Since I ride in all weather conditions, I am also interested in their claim that it will disperse rain more to the outside.

Have you tried it in the rain?

I've rode through a couple of showers on my way back from Scootercade. It has a channel in it that runs around the perimeter of the screen. This tends to catch any water that is moving toward the outside of the screen, and channel it down to the bottom. Be sure to buy a length long enough to completely go around the edge of your screen. I bought 5', and had to snip just several inches off with a pruning shear. I think can do with just 4' with the stock screen - but measure to be sure.

If you do this, try it with just the edging first. Then, if you want to shim out the upper mounts, I did it like this:

1. I bought four 7/8" metal washers at the hardware store. They are each 1/8" thick.

Note: Some folks have used hose washers, which should work with this method too. I'm not sure which is better.

2. Remove the windscreen, and remove the allen head bolts that hold the black bracket that the screen fastens too. Put one washer underneath the bracket on each side where the top bolt passes through. Re-tighten all four bolts. You have shimmed the upper part of the bracket out by 1/8".

Note: I did not put two washers together here, because it looked to me like it would stress the bracket too much (but I have seen other folks do that).

3. Slide the top rubber nuts through the windscreen - and then through the other pair of washers, one on each side. It may be a tight fit. If you put the rubber nut screw in it without threading it, and push on the screw, it will tend to straighten out that buldge in the rubber nut and help you push it through the washer. So now that second set of washers will end up between the backside of the windscreen, and the top of the mounting bracket. You have shimmed the screen out a total of 1/4", without overly stressing any of the parts.

Note: Shimming the base out 1/4" actually does more than you would think. Due to the height of the windscreen, that turns into more than 1/4" of position change as you get to the top of the screen.

The combination of Micro-Swirl edging and screen shimming, leaves me with a screen that I easily look over. Buffeting and wind noise were noticeably reduced. Bug splat is almost gone from my helmet visor. (There is the occasional determined bug that makes it past the wind deflection - I think they angle in from the side. But my visor stays a LOT cleaner.) And If I'm riding with my visor partially open, it no longer slams shut at 45 to 50 mph - It will usually stay open even at 80 mph. All in all, very good results without going to a "barn door" windscreen.
