Product Concept & Specifications
LS2 (Spain)Engineering & Biomechanical Safety Analysis
The LS2 FF406 Carbon utilizes a multi-density EPS liner sandwiched between an outer carbon fiber shell and an inner ABS layer to maximize impact absorption while minimizing overall mass. The aerodynamic profile features a streamlined chin bar and integrated spoiler designed to reduce drag coefficients at highway speeds, directly contributing to the low noise floor measured at 100 km/h. Ventilation channels are strategically routed through the visor mechanism and cheek pads to ensure consistent airflow without compromising structural rigidity.
The LS2 LS2 FF406 Carbon is engineered as a high-integrity Full Face protective system, utilizing a structural shell constructed from Carbon Fiber Composite Shell with ABS Impact Liner. 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 FMVSS 218, 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.
