Abstract: A portable detachable and inflatable motorcycle seat which is adapted for temporary attachment to a motorcycle. It includes an outer case of flexible water repellent material having a longitudinally disposed zipper along one side to provide ready access to the interior. Within the interior there is an inflatable bladder having a connected air passage for introducing or evacuating air therefrom, while on the exterior of one major surface of the case there are disposed a plurality of suction cups for attachment to the motorcycle. Extensions from the suction cups extend into and through the inflatable bladder to strengthen the assembly and to provide reliable attachment. When the seat is not in use, air may be evacuated from the bladder so that the seat can be collapsed and folded into a very small and compact article to enhance portability and storage.
