Features Monolock system: This rack is compatible only with Monolock system cases (Givi's lightest cases, suited to scooters). Composition: This is the metal fitting kit. It does not include the plastic plate, since that always comes in the box when you buy a new Monolock case. Maximum Load: The weight Givi allows for this rack is usually 3kg (or up to 6kg depending on the case), so it is best not to overload it.
