Alpinestars S-M7 Dasher ECE06/DOT Motorcycle Helmets The Alpinestars S-M7 Helmet is precision-engineered for professional off-road racing. It offers a perfect synergy of superior ventilation, elite comfort, and a lightweight aerodynamic composite shell. Featuring Alpinestars' patented A-Head Fitment and innovative PLASMA technology, this helmet is designed for maximum energy dissipation and rider safety in the most demanding environments. Key Performance Features ✅ Aerodynamic Profile: The smooth, streamlined shell is free of external channels that could act as load points during an impact, ensuring total structural integrity. Energy-Deflecting Design: A curved shell surface reduces friction and deflects impact forces away from the head to protect the skull, neck, and spine. PLASMA Technology: Patented PLASMA inserts are strategically integrated into the side pads for high-performance shock absorption, specifically protecting the collarbone area. A-Head Fitment System: Allows riders to easily adjust the height and angle of the helmet for an optimized, personalized performance fit. Patented Visor Release: The visor is designed to detach automatically when subjected to impact energy greater than 15 Joules, regardless of the direction. Hydration System Ready: Features integrated internal channels on both sides to easily accommodate a hydration tube. Advanced Construction & Materials ✅ Multi-Layer Composite Shell: Constructed from a high-performance blend of fiberglass, carbon, and Aramid fiber for durability, stability, and energy absorption. Pre-Preg Molding: Utilizes advanced molding technology to deliver enhanced mechanical performance with an ultra-light overall weight. Ultra-Ventilation System: Equipped with 20 individual ports (13 intakes and 7 exhausts) for maximum airflow and heat exchange. Anti-Microbial Interior: Features a removable 3D foam lining with anti-microbial treatment for long-lasting freshness and comfort. Customizable Fit: Available in 3 shell sizes and 6 consumer sizes (XS to XXL). Fit can be further tailored via exchangeable cheek pads of different thicknesses. Eject System Ready: Designed to accommodate an emergency eject removal system for added safety. Elite Impact Protection ✅ Exceeding Safety Standards: The S-M7 significantly exceeds current regulatory limits for both linear and oblique impact performance. Rotational Force Mitigation: Patented coating technology on the EPS liner reduces rotational acceleration transmitted to the head. Safety Performance: Exceeds the new ECE 22.06 Peak Rotational Acceleration standard by a remarkable 76%. Profiled Chin Bar: Specifically shaped to provide proven impact protection for the lower face. Technical Specifications ✅ Certification: ECE 22.06 and DOT homologation. Weight (Size Medium): 1,280g (ECE) / 1,340g (DOT). Shell Sizes: 3 different shell dimensions for optimal anatomy.
