Clean Air flow and riding position GO SHORT!!
It appears we have much in common. I have a 2006 Tiger, and a 2003 K1200RS, I'm six feet tall.
First: Let me get on my soap box...but I'll be brief, an earlier reply covered many great ideas for you to consider. While for many, it's counter-intuitive to go shorter and end up with less wind noise and turbulence....but IT WORKS. Maybe not for all, but for me it solves the issue.
Second: I purchased the sport screen from Triumph for my Tiger. The screen is shorter and basically a smooth curve design. The factory screen has a shape that puts unbearable turbulence at my helmet level. The sport screen has none! IF I were to use the Tiger at sustained speeds of 80mph and above, I would look for a taller screen to provide more body protection, but that's not how I ride the Tiger
Third: The solution for my K1200RS was simple, I purchased the short but curved (they make a flat one) windscreen from Ztechnik. Like the Tiger as expected, I get some wind in my chest area but NO wind buffeting at my helmet.
Check the member's photo gallery (under my screen name) in our forum for several pictures of my bike with different windscreens. If you wish additional pictures send me a PM and Iíll reply.
Good Luck in your research.
