Optimized contours.
Perfect for standard intermediate head profiles.

Designed for Intermediate Oval head shape; medium-to-high profile fit with slightly roomy crown compared to K3/K4 models; requires specific cheek pads for a tight seal; runs true to size but may feel large for those preferring a locked-in aggressive fit.

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"

Domina la pista y roba miradas en la calle con el AGV K5 S Racer en un llamativo acabado Red. Este casco integral está diseñado para el piloto exigente que demanda tanto precisión aerodinámica como un estilo agresivo. Gracias a su diseño de carcasa aero patentado por AGV, reduce drásticamente la resistencia al viento para minimizar la fatiga a altas velocidades, ofreciendo al mismo tiempo una refrigeración excepcional mediante su avanzado sistema de ventilación multicanal. Su silueta elegante y de perfil bajo no solo mejora la estabilidad, sino que proyecta una estética feroz inspirada en las carreras que impone respeto. En su interior, el revestimiento de confort premium garantiza un ajuste seguro para viajes de larga distancia sin sacrificar la seguridad ni el rendimiento. Con su integración perfecta de forma y función, el K5 S Racer es más que un equipo de protección; es una extensión de tu identidad como piloto.

Engineering & Biomechanical Safety Analysis

El AGV K5 S Racer aprovecha la tecnología distintiva 'Aerodynamic Shell' de la marca, utilizando una mentonera de perfil bajo y conductos de aire integrados para minimizar la turbulencia y maximizar el flujo de aire. Fabricado en policarbonato de alto impacto con un revestimiento interno EPS ajustado para formas de cabeza ovaladas intermedias, equilibra la rigidez ligera con una amortiguación acústica superior gracias al sellado optimizado del visor.

The AGV K5 S Racer Red is engineered as a high-integrity Full Face protective system, utilizing a structural shell constructed from Fiberglass. 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 22.05 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.
