George Kirk, a 23rd century Starfleet officer, owned a PX70: his wife, Winona, told her son James that he would drive it with her seated behind him, which would drive her nuts. In 2263, while stranded on Altamid, Jim Kirk noticed a PX70 in the Franklin's mess hall. He rode the motorcycle as a distraction while his officers rescued the former crew of the USS Enterprise from Krall's camp. To increase the confusion, several holographic replicas of himself and the vehicle were created. (Star Trek Beyond)
