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.
