Due to its three wheeled nature, the ATC required a rider to move their body around on the trike like a sidecar monkey and sometimes counter steer by applying opposite lock in order not to tip over. My first intro to the joys of opposite lock was riding my uncle's ATC in a gravel pit in Ketchikan Alaska. Due to its unique cornering technique and the fact that the ATC could be ridden by someone who had never ridden a motorcycle or even a bike, it was singled out by the safety crowd that appointed itself "your keeper" on its mission to eliminate all risk from society. Along with its partners in crime, the trial lawyers, they were able to convince the U.S. Justice Department to outlaw the sales of 3 wheeled ATV's in 1988 and shake the manufacturers down for $100 million to finance a Consumer Product Safety Commission campaign to buy up all remaining 3 wheelers and spare parts.
