Alpinestars Supertech S-M10 Helmet - Deegan Limited Edition

The Alpinestars Supertech S-M10 is engineered as the pinnacle of motocross and off-road helmet technology, delivering maximum protection, ventilation, and comfort for riders who demand the very best.

Advanced Aerodynamic Design

The streamlined outer profile reduces drag and eliminates external snag points. A curved shell structure helps reduce friction and deflect impact energy away from the head, neck, and spine, creating stability and performance across all speeds and terrains.

Precision Shell Construction

Built using a multi-composite outer shell that includes 3K Carbon Fiber for exceptional strength, Uni-Directional Carbon Composite for radial strength and controlled flex, and an Aramid Fiber layer for penetration resistance. Epoxy resin bonding improves shell integrity and manages energy effectively through the 4-density EPS liner.

Impact and Rotational Protection

Exceeds ECE 22.06 standards by 46% in standard-speed impacts, 23% in low-speed, and 28% in high-speed impacts. Rotational requirements are surpassed by 76% and the integrated MIPS system reduces rotational forces during angled impacts.

Innovative Safety Features

Features a redesigned chin bar for collarbone clearance, softer EPS and flexible rubber edge, removable side pads for improved side impact energy distribution, the ERS Emergency Visor Release System, visor extension for extra roost and sun protection, and compatibility with the Eject Helmet Removal System.

Custom Fit and Ventilation

The patented A-Head Fitment System allows adjustment of helmet height and angle. A total of 28 ventilation ports (18 intakes, 10 exhausts) provide maximum airflow. Four shell sizes and six fit sizes (XS–XXL) ensure precise anatomical fit and balanced weight distribution.

Lightweight Performance

ECE version weighs 1260g (size M), DOT version 1360g, or 1310g with side pads and 1370g with visor extension installed. Built for optimal strength-to-weight ratio to reduce rider fatigue and improve control.

Certifications

Available in ECE R 22.06 and ECE R 22.06 / DOT variants for full global compliance.

The Ultimate High-Performance Helmet

Trusted by elite professional riders worldwide, the Supertech S-M10 delivers top-tier safety engineering, advanced comfort, and industry-leading ventilation — redefining what a motocross helmet should be.
