I found the Triumph Roadster screen to be too short also. I have a replacement from Clearview, it is 2.5" taller and 2" wider, and it is perfect for me. Clearview will make them up to 4" taller than stock. One thing I really like about it is that the view does not distort at the line where the screen ends, it is a smooth transition from looking through it to over it.

Always remember to be yourself. Unless you suck. Then pretend to be someone else.
