Inside a SHOEI Helmet


Few characteristics of a motorcycle helmet are as critical as its first-layer defense. A helmet’s shell absorbs the impact energy in the event of a fall, and distributes that energy over the largest possible area. Combining hand-laid interwoven layers of fiberglass with organic fibers and resin, SHOEI’s proprietary Multi-Ply Matrix AIM & AIM+ shells are not only incredibly strong, they are lightweight, elastic, and come in an industry-leading number of shell sizes to ensure a custom fit for all heads sizes.


SHOEI’s ventilation systems directs cooling, drying air into the helmet, and use areas of low air pressure to the rear of the helmet to draw warm, damp air through the exhaust outlets and into the outside environment. A high priority feature/function during the R&D and testing phases of new helmet development, SHOEI utilizes its state-of-the-art wind tunnel to maximize ventilation performance. The perfect placement and shaping of the inlets and outlets, along with air channels created within the EPS liner, are the basis for optimum ventilation, and is part of what separates SHOEI from our competition.


SHOEI shields protect the rider against wind, dirt, insects and 99% of the sun’s damaging UV rays. Additionally, SHOEI’s 3D injection-molding process ensures a distortion-free view throughout the entire field of vision. All SHOEI shields are tested to ensure compliance with the DOT and SNELL certification standards.


The EPS liner of a helmet is designed to absorb the energies of an impact. SHOEI’s innovative Dual-Layer, Multi-Density EPS liner systems not only provide enhanced impact absorption by utilizing varying densities of foam in key areas around the rider’s head, they are designed to allow cooling air to travel unrestricted through tunnels created in the EPS, further enhancing our superior ventilation characteristics.


SHOEI’s interior systems are carefully thought out to provide maximum comfort and hold during all forms of riding. All current SHOEI helmets come equipped with fully or partially removable, washable, adjustable, and replaceable interior components, and are three-dimensionally shaped to match the contours of a rider’s head for an extremely comfortable fit while maintaining the firm hold necessary for distraction-free, high-speed riding.


The task of the chinstrap is to hold the helmet firmly on the head. This is done by using a chinstrap with proper tensile strength and extensibility. The chinstrap is firmly attached to the helmet shell with metal rivets.
