Snug fit with high cheek pads; designed for intermediate oval head shapes but may feel tight on long ovals due to narrow rear shell

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

"The Helmet"

Redefining the standard for sport-touring excellence, the AGV K1 S merges futuristic aerodynamics with uncompromising safety. This helmet features a sleek, low-drag profile designed to slice through the air at high speeds, reducing fatigue and wind noise for an immersive riding experience. Inside, the precision-molded EPS liner offers a custom-fit feel that cradles your head securely, ensuring protection without sacrificing comfort on long journeys. The integrated sun visor and anti-fog inner shield provide superior visibility in any lighting condition, while the extensive ventilation system keeps you cool during intense rides. Whether you are carving corners on a track or cruising open highways, the K1 S delivers a perfect balance of aggressive style and advanced engineering, making it the ultimate choice for riders who demand the best.

Engineering & Biomechanical Safety Analysis

The AGV K1 S utilizes a fully integrated aerodynamic shell design with an internal EPS liner engineered to meet ECE 22.06 standards while optimizing weight distribution. Its acoustic profile is refined through strategic vent placement and internal channeling that minimizes wind turbulence without compromising the aggressive, race-bred aesthetic of the original K1.

The AGV K1 S is engineered as a high-integrity Full Face protective system, utilizing a structural shell constructed from Thermoplastic. 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 DOT, ECE 22.06 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.
