Just installed the Evotech "tail tidy" kit. Can't say enough good things about it. The body is CNC machined billet aluminum and the fit/finish is outstanding. Compliments the bike's appearance well — was even able to re-use the stock side reflectors. I like the fact that it juts out a little bit so the license plate hangs at approximately the same angle as the stock bracket. The only thing to watch out for is the instructions are pretty much just pictures, you have to look at them carefully, especially when jamming all of the wires into the small cavity. There are a few steps that are different for the GT (and are not documented -- the instructions are based on the R) but you can figure it out.
