@Gav3, without a pix of your ride it is difficult to determine whether your ride is completely stock or if you have any aftermarket kit mounted, eg crashbars, skid plate, aux lights, non-stock mirrors, screen, centrestand, handlebars, etc
For example, from a previous post you where interested in the Givi Trekker 52L top box. If you did mount the top box, have you tested for vibration with the luggage removed?
