Shoei Neotec 3 Sharpen Adult Street Helmets
Developed through extensive wind tunnel testing, the SHOEI Neotec 3 Sharpen combines modular design with controlled aerodynamics. Built with a shock-absorbent AIM shell, the helmet delivers a strong, balanced structure while maintaining stability at highway speeds. The flip-up face cover and integrated face shield add convenience for stops and urban riding without compromising on-road performance.
Inside, the multi-density EPS liner system works with an efficient ventilation layout to manage airflow and comfort over long distances. The QSV-2 internal sun shield provides quick, smooth adjustment for changing light conditions, and the mist-retardant CNS-3C Pinlock shield helps maintain clear vision in a range of weather. A stainless-steel micro ratchet chin strap system ensures secure fastening, while included accessories like the Pinlock sheet, breath guard, and chin curtain round out a well-equipped modular helmet built for real-world riding.
