I own a 2008 Burg 650 executive and am wanting to add more storage space and was looking at GIVI side cases or similar. Problem I'm having is that I am finding that, as with the GIVI brand mentioned, that the side mounts will fit a 650, but not my 650 executive. Any help here is appreciated. Are there any quality HARD saddlebag / side cases and mounts out there to fit my burg? Thanks.
