Givi produces both a topcase and windscreen for the Burgman 400. Givi is the only topcase for the 400 that I am aware of currently. Gustafsson also currently produces windscreens for the 400 in multiple sizes and colors but require you to drill the holes for mounting. Clearview does not yet produce a screen for the 400 but is slated for release later this year. Reviews on the different screens are available elsewhere in the forums. You might want to browse the Aftermarket and Accessories section of the forums for other items available for the Burgmans.
