The BARC speeder gave a single clone trooper increased operational range, great speed, mobility, and firepower otherwise unavailable to the foot soldier.
A more aggressive and bulkier design than slimmer speeder bikes used by the Jedi, the BARC speeder was used in scouting and escort missions on a variety of worlds.
Initially, Stass Allie was to be riding a BARC speeder, but to provide a greater link to the original trilogy, a more recognizable Aratech 74-z speeder bike was used instead.
