Flyscreen round-up

As you can see from the "What mods" thread, I'm seriously addicted to accessories and also suffer a mild chrome fetish.

I'm trying to attain perfection on this bike but haven't quite managed it (yet). I have gone through mods and accessories like a dose of salts, engine cases, handlebars, mirrors, airbox mods, electronic mods, re-maps, all sorts of bolt-on bits and bobs etc, but most of all I've been searching for the perfect windscreen that won't detract too much from the bikes looks and yet provide some measure of protection from the wind blast at speed.

I suffer more than most, as I've always worn an open-face helmet and also enjoy smoking on the go, especially when I'm happily trundling gently through the beautiful Asturian countryside dodging the cowpats. My Marlboros only last about 2-3 minutes and that's keeping the speed down. I have in the past tried using a pipe for a longer-lasting smoke but if you angle it for the most advantageous combustion, it sometimes almost catches fire. I also dread to think what would happen in a head-on crash, I would be taken to hospital with aromatic Virginia smoke coming out of my bottom.

I definitely don't want a full windscreen though, and so far I've tried the following in this order, I've quoted the prices all in Euros to make relative price comparison easy:

OEM Triumph flyscreen 188



This looks fine, although a bit too modern for a retro-classic bike IMHO, but it's well made, even though the edges look a bit unfinished, provides a reduction of wind pressure at chest level and some measure of face wind reduction at speed. Could do with more though, and the shape of the thing prevents you from cleaning the chrome headlamp shell and surrounding area properly. Dirt and corrosion can soon build up there. It's not quickly-detachable either, you have to unscrew the headlamp bolts completely, losing the adjustment, and also the rectifier/regulator fixings to which the thing is also attached. A PITA.

Dart Flyscreen 94.95



This is extremely neat, light and compact, very well made and looks the business. Very reminiscent of 60's flyscreens but made with space-age materials. The fixings are light, strong, well-engineered and its shape allows good access behind for cleaning. If need be, the screen itself can be detached in no time at all, leaving the fixing struts attached to the headlamp, which remains undisturbed and will not need re-adjustment like the Triumph part. This is also handy to clean the inside surface of the screen.

The protection if offers is a bit better than the Triumph one, surprisingly good, and out of proportion to its size. It's also half the price of the factory's flyscreen.


PUIG RACING SCREENS Summer screen 87.57



This is similar in size to Triumphs Summer screen. Spanish-made, good quality and costs just a fraction of the outrageous factory price (at 410...!). I have had one exactly the same on my Virago for over 14 years and it works fine on that. Very little buffeting and with a rigid (if ugly) mounting kit it feels part of the bike. However it doesn't work on the Bonny. I've tried it and removed after the first ride as the buffeting and turbulence was terrible. It works OK on the Virago because of a favourable seat-handlebars-cruiser-style riding position. I could have tried different fitting angles but I've always felt that a screen should be fitted at the same angle as the forks for best aesthetic results. I realise this is putting form before function but that's the way I like my screens.


EMGO bikini fairing 115 average price, varies a lot.



This is a very cheap and cheerful 70's style sports handlebar fairing, but very good value and decently made. I bought one to see if it would be any better than my previous efforts but the screen part of it is just too low for the standard bars, and would simply send the wind blast straight to your chest and face. It might work on something like the Thruxton with its dropped handlebars or clip-ons. You can see from the photo that I did not even bother to fix it permanently, just strapped it on with bungee cords. It's obvious from the height of the screen compared with the bars that it just won't work.


MRA Vario-screen for naked bikes 147 including fitting kit.



With this last one I thought I had found flyscreen Nirvana (I'm a little optimistic):

It's a German-made MRA flyscreen for universal fitting on naked bikes with round headlights. Beautifully-made and with a superbly engineered optional fitting kit that doesn't look fashioned by the local blacksmith. The price for the separate fitting kit seems a bit high (32), but it's worth it for the sheer class of it, you should see the ball-jointed, ground stainless steel struts, linear bearing-like supports and hinged bar clamps.

As well as being a little taller and wider than previous flyscreens, it has a unique feature:

The Vario-Screen has an easily adjustable (no tools are required) spoiler or deflector near its upper edge, which can be set in seven different positions in terms of angle and height to reduce tiresome turbulence and wind noise.
Because the spoiler sits on the screen, the air flow is fanned out and becomes virtually turbulence free. The diffuser effect is increased by putting the spoiler on end because the angle and and the distance are increased at the same time. This technique makes the air flow in such a way that it is possible to have a good relaxed ride at high speed for long stretches. The technique is similar to the well-known "Laminar lip", where the air currents accelerate in passing between the spoiler and the main screen surface and deflect the air that's passing over the top of the screen upwards.

There's some more info on the way these deflectors work, together with some animations and other models on this British importers site:

http://www.bikehps.com/mra/variotouringscreens.html

I'm afraid that after all that aerodynamic BS and marketing puff, it hardly works any better than the humble DART flyscreen and yet it's bigger, uglier, more expensive...I give up...and stay with the DART.

Interesting stuff. Looks like I struck lucky by just buying the Dart!

I have the DART and whilst being very happy with it I have wondered if there was anything better.... it seems not!

Thank Forchetto for taking the time to share your experience.

I use the Slipstreamer Spitfire Screen when the weather is cold, below 45 F. Then I switch to the Dart for the rest of the season. It does a good job of keeping the wind off your torso and is pretty cheap, around $75 US.

I cant believe what a great job the little Dart does. Cheers to you Sleddy for making a great product.

I liked the Dart based on the clean look of it. Then, after reading this great review by Ridge, I didn't hesitate to buy one. I've been very happy with it. But I don't, however, use it for smoking.

0-40mph: I could not really discern a noticeable difference which was great. You still get a nice breeze. or what will be Nice when it gets above 65F.

40-88mph : huge difference the faster you go the more you notice your not being hammered by the wind. There was also a noticeable reduction in wind buffeting at head level. I also noticed a reduction in helmet noise at higher speeds (I'm sure this will vary with different helmets).

Visual Distraction while Riding: None. You barely even know its there.

Conclusion: This screen offers a major improvement in the area of wind buffeting at the chest and head at higher speeds. Riding on the highway is now much more relaxing and I don't need a death grip on the bars to stay on.

I'm giving it ***** (5 stars) and a big
1. Quality made product
2. Super easy to install and remove
3. Looks great on a Bonnie
4. Works as advertised - smoothing the wind buffeting & redirecting flow
5. A very reasonable price at $119.95 at New Bonneville

On a side note: I had lunch with my wife today at a window seat facing the bike. We both commented that the screen was nearly invisible from a few yards away.

Perfect timing for this post, thanks!. I'm torn between the factory color-matched screen and the Dart. Looks like this answered my questions and a Dart is in my future. Still like the color matched based on looks though for the SE at least.

Forchetto - I fee your pain. I have done the flyscreen dance myself. I still have the Triumph OEM screen but it sits up on my shelf. It doesn't get along with my Ace bars. My Dart is what I use whenever I have a screen. I sold the Givi after 2 minutes of riding. Super well made but didn't work for me.

At 6'-3' height, the Dart just sent all the turbulence right at my already noisy Joe Rocket helmet. I took it off ( the screen, not the helmet) and sold it a week later, and its quieter without it, for me at least.

Thanks for the info, I'm getting the Triumph one just to reinforce the bike's sportiness.
