Alpinestars S-M10 Ampress Motocross Helmet - Black / White / Matte

The Alpinestars Supertech family of motocross helmets aims to create highly advanced, protective, and performance-enhancing helmets for riders worldwide. The Supertech S-M10, designed by Alpinestars' Helmet Development team, achieves a perfect balance of excellent ventilation and unrivaled comfort without compromising on any aspect.

The S-M10's design features a smooth, attractive, and aerodynamic profile, eliminating external channels and load points that could compromise the helmet's integrity during an impact. The surface curvature allows for reduced friction on impact, promoting efficient energy transfer to protect the rider's head, neck, and spinal column.

Key Features of the Alpinestars Supertech S-M10:

• The S-M10 shell sizing solution ensures each helmet fit size has the appropriate shell size, offering an anatomical solution for various fit needs worldwide. It includes 4 different helmet shell sizes (S, M, L, and XL) and 6 consumer sizes (XS to XXL), improving comfort, reducing overall weight, and enhancing the helmet's impact effectiveness.
• The Offroad helmet's shell construction uses advanced molding technology with a multi-composite combination: 1) 3K Carbon, a high-density carbon outer layer for improved strength and energy dissipation, 2) Uni-directional carbon composite layer for greater radial strength and controlled deflection during impact, and 3) Aramid fiber layer for critical penetration protection. An epoxy resin bonding enhances strength and energy management, resulting in better energy absorption by the 4 density EPS liner.
• The unique shell lay-up process in the S-M10 construction provides extremely effective impact protection, exceeding current motocross helmet regulation standards for linear and oblique impacts. For direct linear impacts at a 90-degree angle, the SM10 surpasses the new ECE 22.06 standard for 2024 by 46% for regular-speed impacts. The helmet also surpasses the new ECE 22.06 Peak Linear Acceleration standards by 23% and 28% for low-speed and high-speed linear impacts, respectively.
• The S-M10 excels in rotational acceleration and oblique impact performance, surpassing the new ECE 22.06 Peak Rotational Acceleration standard by 76%.
• The redesigned chin bar features a relief section raised to clear the collarbone, with a softer EPS liner extending beyond the helmet shell and covered by a flexible rubber compound, reducing the risk of collarbone injury.
• Removable side pads made from a semi-soft polymer provide added protection, ensuring a larger contact area to disperse impact energy.
• The patented A-Head Fitment System allows easy adjustment of the helmet's angle and height for a comfortable fit.
• The motocross helmet boasts 28 individual intake and exhaust ports, excluding the eye port, with 18 intakes and 10 exhausts, providing exceptional ventilation.
• Equipped with the MIPS Multi-directional Impact Protection System, this motocross helmet enhances rotational impact protection.
• Additional features include ERS Emergency Visor Release, a new Visor Extension for roost and sun protection, and the eject helmet removal system.
• The S-M10 is lightweight, weighing 1260g (ECE) for size medium, and 1310g with side pads and 1370g with the visor extension.

The Supertech S-M10 is the ideal choice for riders looking for a highly advanced and protective motocross helmet. With its perfect balance of ventilation and comfort, along with superior impact protection and innovative features like MIPS and ERS, the S-M10 guarantees a top-notch riding experience.
