Yes they will will fit any xb or 1125 model as the air box covers are all the same. My guess is the reason they only put it in the lighting section was because they only came on lightnings.
yes and Blue was actually the first translucent color to come out. It came out in 2005 when the xb9sx replaces the xb9s. There was hero blue and kick ash (black). The 05 sx was also the first bike to feature frame pucks as well.
