Design Concept & Background
"The best in safety"
The Shark Vemar Sharki Silver Metallic is designed for versatile commuters and touring riders requiring multi-mode adaptability, delivering flip-up versatility for city stops and sealed protection at speed. Built around a Advanced Multi-Composite (Carbon-Aramid-Glass / AIM+) shell weighing a solid 1681g, its multi-density EPS matrix is aerodynamically sculpted to isolate cabin noise to ~88 dB while dissipating kinetic impact forces across ECE 22.06 benchmarks. Inside, 3D laser-cut cheek pads tailor naturally to an Intermediate Oval profile with dedicated eyewear relief channels, secured by track-proven Double D-Ring retention for confident all-day riding.

Product Concept & Specifications
Shark (France)Engineering & Biomechanical Safety Analysis
Features Carbon-On-Skin composite structure with CFD aerodynamic wind-tunnel tuned rear spoiler profile paired with Autoseal visor mechanism pressing the shield onto the helmet gasket for rain and sound insulation. The interior utilizes Bamboo fiber eco-friendly lining with EasyFit glasses grooves for riders wearing spectacles with pre-shaped speaker cutouts for seamless Bluetooth comms integration.
The Vemar Sharki 银色金属漆 is engineered as a high-integrity Modular protective system, utilizing a structural shell constructed from Composite. 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 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.
