中高轮廓贴合；与 K3/K4 相比顶部略显宽松，需要特定的颊垫以确保密封；尺寸标准，但对于偏好“紧致锁定”式侵略性贴合感的骑手可能会感觉偏大。
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"
通过 AGV K5 S 体验赛道传承与日常舒适的完美融合。这款全盔杰作将 AGV 传奇的 A-9 外壳技术与集成的 MIPS® 安全系统相结合，在不牺牲风格的前提下确保无与伦比的保护。专为追求精准的严谨骑士设计，K5 S 拥有流畅且极具侵略性的美学设计，在道路上引人注目。其先进的通风系统提供卓越的气流，确保您在激烈骑行中保持凉爽，而其空气动力学轮廓显著减少了高速行驶时的风噪和疲劳。内衬采用优质的吸湿材料，能够贴合您的头部提供定制化的佩戴感。无论您是在城市街道穿梭还是在开阔的高速公路上巡航，K5 S 都提供了安全、性能和意大利设计卓越的无缝融合。
AGV K5 S represents an empirical engineering balance between aerodynamic stability and high-absorption cranial protection. Developed under AGV's strict quality assurance standards in Italy, the shell profile is precision-molded to minimize high-velocity turbulent drag while maintaining comprehensive multi-axis impact attenuation.
Within the Full Face segment, ergonomic weight distribution and acoustic insulation are paramount. The chassis geometry is tailored to distribute mass directly above the cervical pivot axis, counteracting high-speed buffeting and minimizing long-distance rider fatigue. Inspect the verified laboratory telemetry and structural analysis below for detailed performance parameters.

Product Concept & Specifications
AGV (Italy)Engineering & Biomechanical Safety Analysis
AGV K5 S 采用品牌专有的 A-9 外壳结构，提供坚固的 EPS 内衬和集成的 MIPS® 安全系统，以提供卓越的旋转冲击保护。其空气动力学设计具有优化的气道，在保持适用于高速旅行的低阻力系数的同时，最大限度地提高了冷却效率。
The AGV K5 S 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.
