Expertly engineered for off-road racing, the S-M7 Dasher Helmet delivers a superior blend of ventilation, comfort, and lightweight performance. Its aerodynamic composite shell features patented PLASMA technology for critical energy dissipation and an A-Head fitment system for a customized, stable fit. This ECE 22.06 certified helmet exceeds safety standards, providing elite-level protection for motocross riders in all conditions.

Aerodynamic Design: Features a smooth, streamlined composite shell engineered to eliminate load points during impact and maintain structural integrity.
Energy-Deflecting Shell: The curved exterior surface reduces friction and deflects impact forces away from the head to protect the skull, neck, and spine.
PLASMA Technology: Patented Alpinestars PLASMA integrated into the side pads provides high-performance shock absorption to dissipate energy in the critical collarbone area.
A-Head Fitment System: Patented technology allows riders to easily adjust the helmet's height and angle on the head for a personalized, optimized performance fit.
Patented Visor Release: Engineered to automatically detach when subjected to impact energy greater than 15 Joules, reducing rotational injury risks regardless of impact direction.
Optimized Shell Sizing: Available in 3 shell sizes across 6 consumer sizes (XS-XXL) to ensure an anatomical fit, reducing weight and maximizing impact effectiveness.
Hydration System Ready: Includes integrated internal channels on both sides of the shell to easily accommodate hydration system plumbing.

Multi-layer composite shell constructed from a blend of fiberglass, carbon, and Aramid fiber for superior impact protection and force dissipation.
Patented A-Head Fitment System allows for precise adjustment of the helmet's angle and height to optimize protection and fit.
Advanced ventilation system featuring 20 individual intake and exhaust ports (13 intake, 7 exhaust) for maximum airflow and heat management.
Eject Removal System ready, featuring a specialized removable insert on top of the EPS to facilitate safe helmet removal in emergencies.
Removable 3D foam comfort lining with anti-microbial treatment for long-lasting freshness and hygiene.
Customizable fit via Alpinestars genuine replacement cheek pads, available in various thicknesses and compatible across all shell sizes.
Lightweight performance: ECE 1280g and DOT 1340g (Size Medium).
Fully compliant with ECE 22.06 and DOT homologation standards.

Advanced pre-preg composite shell molding technology for enhanced mechanical performance and ultra-lightweight construction.
Unique shell lay-up process engineered for high-efficiency impact protection, exceeding current regulatory standards for linear and oblique performance.
Integrated rotational impact protection system combining an optimized EPS liner shape and specific internal surface coating to reduce rotational acceleration.
Patented Specific Coating technology reduces rotational acceleration transmitted to the head, exceeding ECE 22.06 Peak Rotational Acceleration standards by 76%.
Profiled chin bar construction designed for specialized impact protection.
