The Alpinestars Supertech helmet family was designed with a clear objective: to create the most advanced, protective, and high-performance helmets for riders worldwide. With the S-M10, Alpinestars engineers developed a helmet that combines exceptional ventilation, unparalleled comfort, and extreme lightness, without compromising safety. Its streamlined aerodynamic design minimizes pressure points and the risk of snagging in the event of an impact, while optimizing energy distribution and dissipation for maximum protection of the head, neck, and spine. The S-M10 helmet thus represents the absolute benchmark in technology, safety, and performance in the world of motocross and off-road riding.

Four-shell sizing system (S, M, L, XL) and six user sizes (XS to XXL) for a precise anatomical fit, increased comfort, and reduced weight.
Newly redesigned chin bar with a raised clearance zone to prevent contact with the collarbone and a soft EPS liner covered with flexible rubber for enhanced safety.
Patented A-Head system allowing for personalized adjustment of the helmet's height and angle for an optimal fit.
Exceptional ventilation with 28 vents (18 inlets, 10 outlets) ensuring maximum airflow.
Integrated ejection technology for safe helmet removal in an emergency.
Ultra-lightweight: 1260 g (ECE), 1310 g with side pads, 1370 g with visor extension.
ECE R 22.06 certified for superior safety.

3K Carbon – high-density outer layer for optimal strength and energy dissipation.

Unidirectional carbon – provides enhanced radial strength while allowing controlled deflection to reduce transmitted forces.

Aramid fiber – protects against penetration for maximum safety.
High-performance epoxy resin bonding ensures superior strength and energy management.
Four-density EPS liner optimizes impact absorption through uniform energy distribution.
Exclusive shell layering technology provides protection against linear and oblique impacts well above regulatory requirements.
Exceptional impact performance:

46% above ECE 22.06 standard for linear impacts at normal speed.

23% at low speed and 28% at high speed, significantly exceeding the new 2024 requirements.
