Replacement rear spoiler for ARAI Contour-X helmets. This aerodynamic rear spoiler features a one-piece exhaust function operated by a 3-way switch and is inspired by advanced race-derived designs but redesigned for touring use. Positioned slightly more forward on the shell and fed by three ports, it efficiently draws air while smoothing airflow over and from the sides of the helmet. The result is improved high-speed stability and reduced buffeting—especially when overtaking on highways—helping to decrease rider fatigue on long rides. Manufactured to be as thin and light as possible, the spoiler is engineered to crush or break away on impact so it does not affect the helmet’s protective performance.
