Hepco&Becker's fixed, black side pannier carriers are designed to securely attach to your Kawasaki Z 550 (1983-1989) or 750 GT (1982-1985) motorcycle frame. These carriers are compatible with nearly all Hepco&Becker Touring side pannier systems. Your panniers are firmly and theft-proof attached to the carriers using a metal locking mechanism. An additional locking adapter is required for this purpose, which is typically included in the pannier set. The locking adapter is fastened to the rear right and left of the carrier and provides the attachment point for the pannier locking mechanism. These model-specific carriers are solidly constructed and offer effective protection for the rider's or passenger's legs in case of a fall. Hepco&Becker side pannier carriers can often be combined with our rear carriers without issues. Please refer to the installation instructions and model-specific notes for guidance. These carriers are made of steel tubing and manufactured in Germany. They are securely bolted to the motorcycle frame and feature a high-quality surface finish. It's important to note that these carriers typically fit most Hepco&Becker hard shell side panniers with some possible model-specific restrictions. In most cases, the turn signals remain in their original positions, but they may need to be repositioned in some instances to ensure a certain beam angle. Please follow the product's installation instructions. Included in the package are the right and left carriers, along with the necessary mounting materials and a detailed manual. Luggage systems of this kind generally do not require a General Operating Permit (ABE) and do not need to be registered. The tube diameter is 16 mm.
