Verified Safety Snapshot
How this helmet’s verified certifications map to recognized safety homologations and crash testing.
Safety standards compliance is based on official manufacturer documentation and public safety laboratory test results. Always verify regional compliance labels on the physical helmet prior to use.
Verified Fit & Sizing Guide
Head shape profile matching and interactive size calculator based on verified manufacturer dimensions.
Fly Racing Kinetic Pearl White is designed for Dirt/MX use. Specific fit notes depend on individual head shape and size selection.
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
"Ride Safe, Ride Fast"
The Fly Racing Kinetic Pearl White is purpose-built for off-road riders demanding massive aerobic cooling and roost deflection, pairing extreme cooling throughput with competition-grade roost protection. Built around a High-Yield Impact-Resistant Polycarbonate / Lexan shell weighing 1414g, its multi-density EPS matrix is aerodynamically sculpted to isolate cabin noise to ~98 dB while dissipating kinetic impact forces across DOT benchmarks. An ultra-breathable, antimicrobial interior liner stabilizes the helmet during aggressive terrain vibration, locked in securely with track-proven Double D-Ring retention.

Product Concept & Specifications
Fly Racing (United States)Engineering & Biomechanical Safety Analysis
Features Advanced multi-composite aerodynamic shell geometry engineered for optimal impact absorption and stability paired with Anti-scratch Class-1 optical shield with Pinlock anti-fog lens compatibility and toolless quick-release. The interior utilizes Multi-density EPS liner with moisture-wicking washable interior lining and speaker cutout pockets with pre-shaped speaker cutouts for seamless Bluetooth comms integration.
The Kinetic 珍珠白 is engineered as a high-integrity Dirt/MX protective system, utilizing a structural shell constructed from Polymer. 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 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.
