It can hold up to two flip-up helmets. It has the "Handle Lock System", a lock that allows you to close the top case and secure it to the bike at the same time.

They are designed to allow full use of the available capacity (23 litres) and the upper cockpit opening allows the user to access the load without having to get off the bike.
