I do drive a lot on the European highways, including the Autobahn.
My setup included the big Roadster screen and Triumph leather bags until now, and I was never really happy with speeds over 100 mph. It was fine for a moment, just to enjoy the endless power of the engine, but if I stayed at hi speed for a longer time, wind gusts were frequently diminishing the fun.
For example overtaking a truck at 100+ mph, when the wind came from the side was always kind of nerve-wrecking, because the big screen would catch the turbulence behind the truck and shake the handlebar. I never went faster than 130 mph til now, because I was really afraid of a tank slapper.
So I decided to search for a slimmer windshield that will still offer decent protection. I realized that the market for double headlight windshields is comparatively small, but I found a few options I liked.
Here is the one that I finally bought and mounted:
Triumph Rocket III - Custom Cruiser Screen - Skidmarx UK Ltd
Windshield was a bit fiddly to install, but has a very wide range of possible settings, so it should fit for almost everybody. Quality is not perfect but fine. Price was very reasonable.
I have only had time for a short test ride yet, but things are looking good. Protection is still acceptable, no buffeting and seems she is more stable at hi speed now.
