Just like the original luggage system created by Hepco & Becker, this tank bag system provides an initial base that is bolted to your bike; allowing for attachment of luggage without coming into contact with any painted surface of the bike so there is no need to worry about damaging your pride and joy.The bag itself is molded to a hard shell composite of abrasion resistant polyester D1200 to stop any folding or shape changing from use over the years. Each bag is attached with reflective triangles for increased visibility while riding in the dark. The zippers are water resistant and can be locked with the optional safety lock.
