Open face design offers unrestricted peripheral vision; Gloss Black finish may show fingerprints; Bell Custom 500 fits most head shapes but requires cheek pad adjustment for optimal fit.

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 Custom 500 Gloss Black combines sleek styling with advanced engineering, delivering a helmet that not only looks great but also provides exceptional performance and protection.

Engineering & Biomechanical Safety Analysis

The Bell Custom 500 Gloss Black features a fiberglass shell for durability and impact resistance, offering solid safety performance for an open-face helmet. Its intermediate oval head shape ensures a comfortable fit for most riders, while the open-face design prioritizes ventilation and airflow. The helmet provides basic ventilation through its open design, making it suitable for warm weather or casual riding. Comfort is enhanced by its lightweight construction and adjustable fit, though it lacks advanced safety features like MIPS or extensive ventilation systems found in full-face models.

The Bell Custom 500 Nero lucido is engineered as a high-integrity Open Face protective system, utilizing a structural shell constructed from Fiberglass. 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.
