Africa Twin CRF1100L Honda Genuine Option Aluminum Top Case Aluminum Carrier Bracket Although the mounting screws are not genuine, they can be installed as shown in the photo. Since the Africa Twin has a lot of vibration, it is recommended to apply screw lock adhesive for installation. Both SD10 and SD15 can be installed. Installation is easy. The order is: bolt → aluminum carrier bracket → spacer → genuine carrier → washer → nut from the top. The aluminum top case in the installation photo is a third-party Givi OBKN58A, but Givi's Monokey cases can be installed even if they are not genuine top cases. However, in my experience, some adjustment is required for models other than the OBKN series. For the DLM series, it fit perfectly by inserting one washer on the front protrusion of the bracket and raising it slightly. The WL901 weightless could be installed perfectly by removing the rear rubber base.
