Take the shield the bike comes with to a glass shop, and have them cut it down to the height you want. That will be your cheapest, and easiest option.
That's a great idea. Anybody know the difference in height between the tall screen that comes with the SE and the midsize screen? That's about the size I want. I'll also get something small for summer. I have a Dart flyscreen on my T100 and I love it. I see that they now make the Dart for the TBird. I might look into that. The only reason I'll put something on in the summer is to keep the wind off my chest for highway riding.
