Alpinestars Supertech S-M10 Era B Motocross Helmet

Alpinestars Supertech S-M10 Motocross Helmet

The goal of the Alpinestars Supertech helmet family was to develop the most advanced, protective, and high-performance helmets for riders worldwide. With the S-M10, Alpinestars' helmet development team has designed the helmet to offer the perfect blend of excellent ventilation and unparalleled comfort, creating a helmet with the lowest possible weight without compromising in other areas. The design of the S-M10 offers a smooth, attractive, aerodynamic profile that is streamlined and free of external ridges and features that could act as stress points in an impact or compromise the overall integrity of the helmet construction. The surface curvature promotes reduced friction upon impact, allowing for deflection and the most efficient energy transfer to protect the rider's head from direct force on the skull, neck, and spine.

Features:

• The S-M10 shell sizing solution ensures that every helmet size has its own properly fitted shell size, providing the best anatomical solution for diverse fit requirements worldwide. With 4 different helmet shell sizes—S, M, L, and XL—and 6 consumer sizes from XS to XXL, it ensures that the rider has the right fit, which not only improves comfort and reduces overall weight but, above all, improves the helmet's effectiveness in an impact.
• The helmet shell construction uses state-of-the-art molding technology with a multi-composite combination: 3K carbon, an outer layer of high-density carbon that improves the strength and efficiency of energy dissipation across the shell; a unidirectional carbon composite layer that provides significantly higher radial strength around the shell, preventing compression while allowing controlled flexing to reduce transmitted impact energy; and an aramid fiber layer that provides critical penetration protection. This layer combination is made even more effective by an epoxy resin bond, ensuring the best possible strength and energy management. The limited flexing of the outer shell means that energy spreads further and is better absorbed by the 4-times densified EPS liner.
• The result of the unique shell construction process used in the S-M10 is extremely effective impact protection. The S-M10 offers linear and oblique impact performance that exceeds current standard limits for helmets. In a direct linear impact—that is, an impact at a 90-degree angle between the helmet and an object—the S-M10 exceeds the new 2024 ECE 22.06 standard by an average of 46% at normal impact speeds. New to the ECE 22.06 standard are requirements for low- and high-speed linear impacts, where the S-M10 exceeds the new ECE 22.06 standards for linear peak accelerations by 23% and 28%, respectively.
• In terms of rotational acceleration and performance in an oblique impact—where the impact energy comes from an angle other than a linear 90-degree or perpendicular straight impact—the S-M10 exceeds the new ECE 22.06 standard for peak rotational acceleration by 76%.
• The new profile of the redesigned chin guard, where the lower area has been specially shaped to create a relief zone that leaves the collarbone free, features a new, softer EPS liner that extends beyond the actual helmet shell and is covered by a more flexible rubber compound, reducing the risk of collarbone injury.
• Removable semi-soft polymer cheek pads provide additional protection and a larger contact area to distribute impact energy.
• The patented A-Head Fitment System allows for easy adjustment of the angle and height at which the helmet sits on the head.
• Ultra-ventilated helmet with 28 individual air inlets and outlets, excluding the field of vision, with 18 air inlets and 10 outlets.
• MIPS, Multi-directional Impact Protection System (protection system for falls with oblique impacts).
• ERS system for emergency visor removal and a new visor extension for protection against sun and dust.
• The new Eject technology includes the Eject helmet removal system.
