The Aratech 105-K lancer bikes, more commonly known as lancer swoop bikes, were swoop bikes made specifically for lancer trooper squads to carry them during their covert raids and jousting duels.
The Aratech 105-K lancer swoop craft were painted white, possessed a black visor-like image on the front, and had a crest like the clone trooper armor of the clones that rode on them. Since the model lacked a safety harness, the impact of a lance against an obstacle could well be expected to unseat the rider. The 105-K could attain speeds of several hundred kilometers per hour and could, at high speeds, climb steep cliffs.
During the Battle of Muunilinst, Jedi General Obi-Wan Kenobi led a group of lancer troopers to counteract the raids performed by Durge's IG lancer droids. After apparently killing the mercenary, Obi-Wan used his swoop to gain speed and propel himself to the top of the InterGalactic Banking Clan's command center on the planet.
