Quick Facts at a Glance
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.
Designed for oval head shapes; offers a roomier fit compared to the Bell SRT Air due to modular shell design.
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
"The Best Protection"
The Bell SRT Modular is designed for versatile commuters and touring riders requiring multi-mode adaptability, pairing a quick-flip chin bar with certified impact protection. Featuring a High-Yield Impact-Resistant Polycarbonate / Lexan architecture at a featherweight 1344g, it combines progressive kinetic energy dissipation across DOT, ECE 22.05 certifications with an acoustically tuned ~88 dB aero profile. A plush, washable 3D comfort liner cradles Intermediate Oval head shapes with zero temple pinch for glasses wearers, locked in securely with track-proven Double D-Ring retention.

Product Concept & Specifications
Bell (United States)Engineering & Biomechanical Safety Analysis
Features 3K Carbon Fiber shell featuring Flex Impact Liner with progressive three-layer density rotational energy management paired with Panovision Class-1 optics visor with extended lateral field of view. The interior utilizes Virus CoolJade anti-bacterial lining paired with Magnefusion magnetic removable cheek pads with pre-shaped speaker cutouts for seamless Bluetooth comms integration.
The SRT Modular is engineered as a high-integrity Modular 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 ECE 22.05, 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.
