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

"Passion for Safety"

通过 Nolan X-704 揭面盔,体验意大利工程技术与现代多功能性的完美融合。专为追求极致安全且不愿牺牲风格的动态骑手设计,这款头盔采用时尚的白色涂装,在任何道路上都能脱颖而出。创新的揭面机构可让您在全盔防护与开阔视野的舒适感之间无缝切换,是激情赛道日和长途旅行的理想选择。凭借卓越的通风通道和空气动力学轮廓,X-704 即使在高速行驶时也能保持凉爽且安静。其中间椭圆形头型设计确保标准头型的骑手能够获得稳固且舒适的佩戴体验,而先进的遮阳镜系统则在各种光照条件下提供清晰的视野。选择这款平衡了尖端技术与经典设计的头盔,升级您的骑行体验。

Nolan X-704 White represents an empirical engineering balance between aerodynamic stability and high-absorption cranial protection. Developed under Nolan'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 Modular 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.

Engineering & Biomechanical Safety Analysis

Nolan X-704 采用多密度 EPS 内衬和扩展式固定系统,确保在高速转向操作中精准锁紧头部。其空气动力学外壳设计最大限度地减少了遮阳镜处的风buff影响,同时通过先进的复合材料保持结构刚性。

The Nolan X-704 White is engineered as a high-integrity Modular protective system, utilizing a structural shell constructed from Lexan. 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.
