Verified Safety Snapshot
How this helmet’s verified certifications map to recognized safety homologations and crash testing.
Safety standards compliance is based on official manufacturer documentation and public safety laboratory test results. Always verify regional compliance labels on the physical helmet prior to use.
Verified Fit & Sizing Guide
Head shape profile matching and interactive size calculator based on verified manufacturer dimensions.
Conçu pour une coupe ouverte ; peut sembler serré sur les grandes zones occipitales en raison des coussinets de joues agressifs.
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.

Product Concept & Specifications
Steelbird (India)Engineering & Biomechanical Safety Analysis
Équipé d'une géométrie de coque aérodynamique multi-composite avancée, conçue pour une absorption optimale des impacts et une stabilité accrue, associée à une visière optique de Classe 1 anti-rayures compatible avec les lentilles anti-buée Pinlock et un système de libération rapide sans outil. L'intérieur utilise une coque EPS multi-densité avec une doublure intérieure lavable évacuant l'humidité et des emplacements préformés pour une intégration fluide des systèmes de communication Bluetooth.
The Adonis is engineered as a high-integrity Open Face protective system, utilizing a structural shell constructed from Polycarbonate. 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 22.05, 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.
