Motorcycle stability during a variety of maneuvers is maintained through both rider steering input and body interactions with the seat, tank, footrests, and handlebars. Exploring how rider-vehicle interactions impact vehicle control is critical to creating a comprehensive understanding of motorcycle handling. The present study aims to understand how experienced motorcycle riders influence motorcycle dynamics by characterizing center of pressure (COP) location, force applied at the seat, rider lean angle and offset relative to the motorcycle, and steering angle for various maneuvers. A course was defined on Exponent’s Test and Engineering Center (TEC) track and skid pad that included sections of straight riding, navigating a banked curve, and sharp turning (low speed U-turns, 90 degree turn after a stop, and obstacle avoidance). The task influenced rider response and, in particular, lateral COP location at the seat.
