SHOEI NEOTEC II - Experience the Versatility. When SHOEI first introduced the NEOTEC in 2011, riders worldwide realized not all modular helmets were created equal. With its lightweight, highly-aerodynamic shell, advanced noise reduction, and optimal vision protection, all combined with an ease of use (critical to a modular helmet), SHOEI had indeed achieved new heights in head gear design. But that was just the beginning. Now, with the NEOTEC II, SHOEI has not only improved on already outstanding features, but also introduced design advances to bring their premiere modular design into a whole new era. Aerodynamic Shell Design: Aerodynamic properties are maximized through extensive wind tunnel testing. Dual-layer EPS liner enhances impact absorption and ventilation. Four shell sizes and five liners present increased fit options that help to comfortably fit most head sizes from XS through XXL.
