I like what the Triumph flyscreen did for my T-120. It cleaned up and focused the air very well and now the wind hits me mid chest but I am 6'4". It made the bike a good 500 mile per day bike as opposed to the 300 miles and tire kind of bike. It particularly good when running into a headwind.

The Dart Marlin didn't work for my on my T120. I'm 5'9 and it directed the air straight to my helmet. Very loud wind noise and turbulent.
I now have a Long Haul screen just for long rides, and I added a Puig extender - works like a charm!

I was riding home from a friend's place last night and the traffic was moving between 120-140kmh on the freeway and the windblast on my helmet was starting to get on my nerves. I wear an Arai Rx-7 too so I can't do much better aerodynamics-wise than that.

I love the look of my Speed Twin so I don't want to change it too much. So, if those tiny deflectors work, I'd like to get one. If they are more for style, I will pass. I'd love to hear from those that have installed them.
I put a 1/4 fairing on. Got the unpainted for about $300 from Japan. Wind hits about half way up my helmet

Thanks for the other feedback everybody. I really appreciate it. I think I will just deal with the wind. I have good earplugs and a very aerodynamic helmet.

It's not that I can't take it, I was just hoping that one of those small deflectors would make a difference. I previously rode a Ducati 998 and even though it had a short screen, it was comfortably up to 160kmh.

I bought the Speed Twin for style mostly and I want to keep that style. I will deal with the wind.

If you donít want to get beat up by the wind, get a high enough screen that doesnít also cause buffeting, which is difficult for these small bikes. Or get a different bike. Like a Street Glide.
The wind blast on the Speed Twin is significantly worse then it was on the Street Twin. Why, I have no idea, but it is. The little fly screens donít do much at all to help with it. I have no idea how else you can address bad aerodynamics but Iíd love to know.

Get a Dart Flyscreen.
First watch Stuart Fillingham's video on installing a Dart on his T120.
Second, ignore Stuart's rant on installation and quality; insatallation is a chich and Dart quality is as good as everyone (except Stuart) says. I love Stuart's vids, but you have to put up with his cranky gripes. The Dart flyscreen is equal or better than Triumph offerings and MUCH less expensive.
There are hundreds of picture posts of the Dart Flyscreen installed on Bonnies. I think they enhance the look...sure made my T120 Black look finished!
I just completed a 500 mile blast through the mountains between Anchorage and Homer, Alaska. Mostly at 65 MPH, but plenty of overtakes at 80-90 and a few sprints to tripple digits in passing lanes.
The dart GREATLY improves the tiring blast on your chest. You'll always get full wind (and noise) on your helmet unless you go for a FULL windscreen; but NOEONE puts those on their Bonnies!

The Dart Marlin looks like it might be worth a try - it's cheap enough that I am willing to gamble. Plus, it looks like a piece of cake to take on and off.

My 865 Bonny was the worst naked bike I've ridden for wind blast.

I find my Speed Twin quite acceptable in comparison and (slightly) better than the T120


.

Whenever I see a bike advertised with 'a shed load of extras' I often wonder how well it handled with a deckchair, lawnmower, some hose and a rake strapped to it.
