I've recently fitted a dart marlin screen. Looks cool but doesn't do much for the airflow. Can't say that I'd recommend in tbh.
I have the Street Twin with touring screen which is the largest for the StTwn. It works well. A fly screen offers little protection. Highly recommend the larger screen. Its is not that big and works well. Triumph probably makes a similar size for the T100.
I think Triumph calls it the long haul screen for the T100. Same basic size as the touring screen on the Street Twin. Works and is engineered well. Little if any wind pressure on my torso and head even at freeway speeds.
I've had the quick-attach Triumph Long Haul screens on a 2012 America and my 2014 T-Bird. They fit perfect and are built like tanks, but they're more difficult to take on and off than they should be. Once you get the 'hang of it,' they aren't too bad. The only drawback is the price that Triumph charges. In both cases, I had good protection for my torso and head. They didn't do anything for my hands.
Had a Dart on one of my Bonnies. It was ok, but tbh I don't find the wind "blast" to be that bad, so I took it off. Same with my Speed Triple and XJR. Also, screens look shit on naked bikes.
Thanks gentlemen. I’ll take a long look at the “long haul”. Pretty pricey, sure miss my Aeroflot. Just took the AI off the old girl, motor very happy ( looks better too) Thanks again.
