Alpinestars S-M10 Flood, casque de motocross

The aim of the Alpinestars Supertech helmet family was to develop the most advanced, protective and high performance helmets for riders worldwide. With the M10, Alpinestars' helmet development team designed the helmet to offer the perfect blend of superior ventilation and unrivalled comfort to create a helmet with the lowest possible weight without compromising in other areas.

The design of the M10 offers a smooth, attractive, aerodynamic profile that is streamlined and free from external profiles and features that could act as a stress point on impact or compromise the overall integrity of the helmet construction. The surface curvature favours reduced friction on impact, allowing deflection and the most efficient transfer of energy to protect the rider's head from direct force to the skull, neck and spine.

Features

• The M10 shell sizing solution ensures that each helmet size has its own matching shell size to provide the best anatomical solution for the diverse fit needs 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 that not only improves comfort and reduces overall weight, but more importantly improves the effectiveness of the helmet in the event of an impact
• The result of the unique shell construction process used in the design of the M10 is extremely effective impact protection. The M10 offers linear and oblique impact performance that exceeds the current standard limits for helmets. In a direct linear impact, i.e. an impact at a 90-degree angle between the helmet and an object, the M10 exceeds the new ECE 22.06 standard for 2024 by an average of 46% at normal speed impact velocities. New in the ECE 22.06 standard are the requirements for linear impacts at low and high speed, where the M10 exceeds the new ECE 22.06 standards for linear peak accelerations by 23% and 28% respectively
• In rotational acceleration and oblique impact performance, where the impact energy comes from an angle other than a linear 90-degree or right-angled straight impact, the M10 exceeds the new ECE 22.06 standard for peak rotational acceleration by 76%
• The new profile of the revised chin guard, where the lower area has been specially shaped to create a relief area that leaves the collarbone free, with a new, softer EPS inner lining that extends beyond the actual helmet shell and is covered by a more flexible rubber compound that reduces the risk of collarbone injury
• Removable side pads made from a semi-soft polymer for added protection provide a larger contact area to disperse impact energy
• Patented A-Head Fitment System allows 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 impact)
• ERS system for removing the helmet peak in an emergency and a new extension to protect against sun and dust
• The Eject technology includes the Eject helmet removal system
• Lightweight ECE 1,260 gr., 1,310 gr. with side padding and 1,370 gr. with helmet peak
• Double D-ring fastener

The helmet shell construction uses a state-of-the-art moulding technology with a multi-composite combination:

• 3K carbon, an outer layer of high-density carbon that improves 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 but allowing controlled deflection to reduce transmitted impact energy
• An aramid fibre layer that provides critical penetration protection. This layer combination is made even more powerful by an epoxy resin compound that provides the best possible strength and energy management. The limited deflection of the outer shell means that energy spreads further and is better absorbed by the 4-density EPS liner

Note

• All helmets will be delivered only with the ECE certification by default
