Approximately 4.5kg lighter than the standard bonnet, and an aerodynamic effect due to the placement of air outlets. Generates front downforce to improve grounding performance of the front tire and weight reduction to improve turning performance, contributing to improved handling performance. The inner duct that exerts an aerodynamic effect achieves a weight reduction of about 4.1 kg compared to the standard equipment utility box. Comes with a duct lid and aero bonnet shade that covers the bonnet opening. Hybrid structure with front surface made of CFRP and back surface made of FRP.
