The Happy Trails Top Box Support for the R1150GSA was designed to allow a top box to be run in conjunction with the SU Rack and all size panniers. The narrow profile of the GSA's rear section, coupled with Happy Trails philosophy of keeping racks as slim as possible has made top box fitment tricky. Our Top Box Support allows for the 15, 29, 43, and 47 liter top boxes to be run on the bike (set 90 degrees from the standard mounting position).
Designed to fit the R1150GSA only
Allows a top box to be run while maintaining the narrow profile of the Happy Trails luggage system
Rearward support helps stabilize the notoriously weak BMW GSA tail section
Boxes are set 90 degrees from the standard top box mounting position meaning the box will open from either the left or right, not front or back.
