In designing the Hornet X2, SHOEI utilized its state-of-the-art wind tunnel facility to help develop the optimal balance between airflow, silence and functionality. A large, multi-position lower air intake/defroster optimized for fresh air intake and improved vision, two shutter-controlled upper air vents for optimal air intake and head cooling, four uniquely-positioned rear exhaust outlets to take better advantage of negative pressure suction, and three neck outlet vents work together to yield unrivaled cool air intake and hot air exhaust.
