A storage container of a motorcycle includes a container body defining a storage compartment and a lid functionally connected to the container body. The container body includes an access opening, a bottom wall opposite to the access opening and a side wall extending perimetrally and joined to the bottom wall. The lid connects to the container body to take an open configuration allowing access to the storage compartment by the access opening, and a closed configuration preventing the storage compartment from being accessed. The storage container includes an object blocking system associated with the container body or with the lid adapted to block an object housed in the storage compartment. The object blocking system includes an inflatable member adapted to be operatively received in the storage compartment and which is adapted to have a resting configuration, in which the inflatable member is substantially deflated.
