Alpinestars Supertech M10 Flood Motorcycle Helmets

The Alpinestars S-M10 is the pinnacle of the Supertech family, designed to be the most advanced, performance-enhancing off-road helmet available. Engineered by Alpinestars’ elite development team, it achieves the perfect balance of excellent ventilation, unsurpassed comfort, and the lightest weight possible—all without compromising safety or structural integrity.

Performance Design & Aerodynamics

• Streamlined Profile: An attractive, aerodynamic design free of external channels that could act as load points during an impact.

• Surface Curvature: Engineered to reduce friction on impact, promoting deflection and efficient energy transfer to protect the head, neck, and spinal column.

• Optimized Shell Sizing: Features 4 dedicated shell sizes (S, M, L, XL) and 6 consumer sizes (XS to XXL) to provide an anatomical fit that improves both comfort and impact effectiveness.

Key Features for Professional Riders

• Collarbone Protection: A redesigned chin bar with a sculpted relief section and soft EPS liner prevents collarbone injuries during extreme maneuvers.

• A-Head Fitment System: Patented technology allowing for precise adjustment of the helmet's angle and height for a customized fit.

• Massive Ventilation: An ultra-ventilated system featuring 28 individual ports (18 intakes and 10 exhausts) for maximum cooling.

• Emergency Systems: Equipped with the "Eject" helmet removal system and ERS (Emergency Visor Release) to ensure safety in crash scenarios.

• Roost Protection: Includes a new visor extension to shield against the sun and flying debris.

Advanced Multi-Composite Construction

• 3K Carbon Outer Layer: High-density carbon that maximizes strength and dissipates energy efficiently across the shell.

• Uni-Directional Carbon: Provides superior radial strength to prevent shell compression while allowing for controlled deflection.

• Aramid Fiber Layer: Delivers critical protection against penetration.

• 4-Density EPS Liner: Bonded with epoxy resin for elite energy management, spreading impact forces across a wider area.

World-Class Safety & Protection

• MIPS Integration: Features the Multi-directional Impact Protection System to significantly reduce rotational brain forces.

• Linear Impact Excellence: Surpasses the ECE 22.06 standard by an average of 46% for regular-speed impacts.

• Acceleration Safety: Outperforms ECE 22.06 Peak Linear Acceleration standards by 23% (low-speed) and 28% (high-speed).

• Rotational Protection: Exceeds Peak Rotational Acceleration standards by a massive 76%.

• Protective Side Pads: Removable semi-soft polymer pads provide a larger contact area to spread impact energy.

Technical Specifications

• Certifications: ECE R 22.06 and DOT approved.

• Weight (Size Medium): 1,260g (Shell) / 1,310g (with pads) / 1,370g (with visor extension).
