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.
Arai VX-Pro4 is a dedicated off-road/dirt helmet designed for motocross and enduro. It features a removable visor, integrated goggles mount, and ventilation optimized for high-heat environments. The fit is generally true to Arai's standard sizing (often slightly roomier than Japanese domestic market fits). Designed specifically for Intermediate Oval head shapes.
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
"Safety is our business"
The Arai VX-Pro4 Gloss White is engineered for punishing motocross motos and technical single-track trails, delivering lightweight balance and wide-vision goggle accommodation. Featuring a High-Yield Impact-Resistant Polycarbonate / Lexan architecture at 1404g, it combines progressive kinetic energy dissipation across DOT, Snell M2020, ECE 22.05 certifications with an acoustically tuned ~97 dB aero profile. 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
Arai (Japan)Engineering & Biomechanical Safety Analysis
Features Complex Laminate Construction (CLC) with PB-SNC2 peripheral belt reinforcement and R75 smooth shell geometry for glance-off impact energy redirection paired with VAS (Variable Axis System) shield mechanism with dual-latch shield lock and IC Duct 5 ventilation intake ports. The interior utilizes One-piece multi-density EPS liner with Eco-Pure anti-microbial removable Dry-Cool interior lining with pre-shaped speaker cutouts for seamless Bluetooth comms integration.
The VX-Pro4 Gloss White is engineered as a high-integrity Dirt/MX protective system, utilizing a structural shell constructed from cLc. 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 22.05, DOT, Snell M2020 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.
