Design Concept & Background
"Built for Speed"
The GMax GM-11 is engineered for riders who demand reliability and performance on dirt trails and motocross tracks. Featuring a high-impact polycarbonate shell, this helmet offers a robust barrier against debris and impact, ensuring rider safety without compromising on weight. Its advanced ventilation system is meticulously designed to provide optimal airflow, effectively reducing heat buildup and rider fatigue during intense, extended sessions. The interior is shaped in an intermediate oval profile, catering to the most common head dimensions for a secure, comfortable fit that stays stable even on the roughest terrain. With sleek, aggressive styling that reflects its off-road pedigree, the GM-11 balances durability with essential functionality. The wide eye port ensures excellent peripheral vision, allowing riders to maintain focus on the path ahead. Whether you are a weekend enthusiast or a dedicated off-road competitor, the GMax GM-11 delivers the protection, comfort, and airflow necessary to push your limits with confidence.

Product Concept & Specifications
GMax (United States)Engineering & Biomechanical Safety Analysis
The GMax GM-11 Course TC-2 helmet features a polycarbonate shell, providing excellent impact protection and durability. It offers a comfortable fit with an intermediate oval head shape and good ventilation to keep riders cool during long rides. The helmet also features advanced safety technology for enhanced protection.
The GMax GM-11 Course TC-2 is engineered as a high-integrity Dirt/MX protective system, utilizing a structural shell constructed from Polycarbonate. 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 22.06 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.
