The 74-Z speeder bike, sometimes referred to as the Imperial speeder bike due to its use by scout stormtroopers of the Galactic Empire, was a speeder bike manufactured by Aratech Repulsor Company used for reconnaissance purposes, as well as rapid transportation in combat zones.
They were capable of reaching speeds up to and beyond five hundred kilometers per hour, and had a flight ceiling of twenty-five meters. 74-Zs were the military variant of the civilian 74-Y. They were controlled by handlebars located towards the front of the vehicle, and foot pedals slung underneath adjusted speed and altitude.
The highly maneuverable vehicles were equipped with sensor and communications devices located between the handlebars, including a comlink and a comlink-jamming device. They were armed with a forward rotating blaster cannon for combat.
They were also equipped with a very powerful boost that could propel them over vast distances in a shorter amount of time. [Wookieepedia]
