Helmet Alpinestars Supertech SM10 United Red White

Elevate your riding experience with the Alpinestars Supertech SM10 United helmet.

Specifications:

• Optimized shell sizing: dedicated shells across the size range create a more anatomical fit, reduce bulk, and improve impact efficiency.
• Clavicle-friendly chin bar: raised base and flexible edge help clear the clavicle to reduce injury risk.
• A‑Head Fitment System adjustability: allows you to fine-tune the crown height and helmet angle for a personalized fit and balanced riding posture.
• High-flow ventilation: strategically placed intake and exhaust ports maintain continuous airflow to keep you cool and focused.
• Eject helmet removal system: integrated design that enables safe and controlled helmet removal by emergency services after an incident.
• Lightweight construction: minimizes neck fatigue for enhanced comfort during long MX motos.
• The S-M10 is available in 2 versions: ECE R 22.06 and ECE R 22.06/DOT.
• In rotational acceleration and oblique impact performance, the S-M10 exceeds the ECE 22.06 standard for maximum rotational acceleration by 76%.
• Removable semi-rigid polymer side pads increase the contact area to help dissipate impact energy.
• MIPS multidirectional impact protection system.
• ERS emergency release visor system and a new visor extension for roost and sun protection.
• The shell lamination uses multi-composite molding: an outer layer of high-density 3K Carbon, a layer of unidirectional carbon composite for radial strength, and a layer of aramid fiber for penetration resistance, all bonded with epoxy resin for structural integrity.
