The Alpinestars S-M10 is a dirt/MX specific helmet designed for motocross and off-road riding. It features a multi-density EPS liner for impact absorption and an extended rear coverage typical of MX helmets, optimized for Intermediate Oval head shapes.

How to measure

Wrap a cloth measuring tape around your head just above your eyebrows and ears. Pull the tape comfortably snug, read the length, and repeat for consistency.

Design Concept & Background

"Ride Safe"

The Alpinestars S-M10 is engineered for punishing motocross motos and technical single-track trails, delivering lightweight balance and wide-vision goggle accommodation. Featuring a Aerospace-Grade 100% Carbon Fiber architecture at a featherweight 1290g, it combines progressive kinetic energy dissipation across DOT, ECE 22.06 certifications with an acoustically tuned ~97 dB aero profile. An ultra-breathable, antimicrobial interior liner stabilizes the helmet during aggressive terrain vibration, locked in securely with track-proven Double D-Ring retention.

Engineering & Biomechanical Safety Analysis

Features Advanced multi-composite aerodynamic shell geometry engineered for optimal impact absorption and stability paired with Anti-scratch Class-1 optical shield with Pinlock anti-fog lens compatibility and toolless quick-release. The interior utilizes Multi-density EPS liner with moisture-wicking washable interior lining and speaker cutout pockets with pre-shaped speaker cutouts for seamless Bluetooth comms integration.

The S-M10 is engineered as a high-integrity Dirt/MX protective system, utilizing a structural shell constructed from Carbon Fiber. This structural layup is engineered to provide progressive kinetic energy dissipation during impact deceleration, distributing localized shock across outer lamina layers while minimizing deformation transfer into the internal multi-density EPS liner.

Certified to ECE 22.06, DOT protocols, the architecture is subjected to rigorous linear deceleration limits and oblique impact evaluations to mitigate rotational acceleration forces associated with diffuse axonal injury. For a deeper breakdown of rotational thresholds and impact testing speeds, consult our ECE 22.06 vs DOT vs SNELL engineering benchmark.

Internal geometry follows a Intermediate Oval cranial profile, designed to mitigate focal pressure hot spots across the parietal ridges while maintaining uniform radial clamping pressure along the zygomatic arch. Riders seeking optimal retention stability and break-in guidance should review the cranial aspect ratios and head shape guide as well as our 3D cheek pad density protocol.

Shell composite integrity and acoustic sealing are further optimized through channelized EPS porting and aerodynamic laminar profiling. To learn how shell composites resist stress cracking under prolonged environmental cycling, inspect the composite material comparative matrix.
