Bell Moto Moto-10 Spherical Motorcycle Helmets

The Moto-10 Spherical is our most advanced off-road helmet, trusted by top Motocross and Supercross athletes, including icons like Eli Tomac. This helmet is not merely an iteration; it represents the evolution of full-face protection, setting a new industry standard. Since developing the first full-face motocross helmet in 1975, Bell has consistently focused on creating leading solutions that enhance rider performance and confidence. The Moto-10 achieves a winning combination of increased protection, weight reduction, and extreme airflow, born directly from athlete-driven design and feedback.

✅ Core Safety Architecture and Proprietary Technology

The Moto-10 is built around revolutionary safety and performance systems to ensure maximum rider security and focus:

Spherical Technology™: Powered by Mips®, this proprietary technology helps redirect impact forces by allowing the outer layer to rotate around the inner layer. This integration achieves market-leading design and superior brain protection without compromising weight or comfort.
NMR™ Bumpers (No Missed Races): Utilizing a softer EPP material, two dedicated bumpers on either side of the helmet compress under load but bounce back, reducing the likelihood of injury from the helmet contacting the rider's body.
Visor Architecture Innovation: The Flying Bridge™ Visor design offers increased flexibility and improved airflow while eliminating the traditional center post and screw, which allows for increased energy management material in a high-impact zone.

✅ Advanced Thermal Management and Operational Features

This helmet features extreme ventilation and key utility components for sustained, high-level performance:

Thermal Exchange Airflow System™ (T.E.A.S.): Our most extreme ventilation system, engineered to suck in cool air like a vacuum and vigorously expel hot air through side and rear exhaust ports.
Segmented 3K Shell: This specialized shell design provides a large exhaust vent, working in tandem with T.E.A.S. for superior thermal management and airflow, ensuring the rider stays cool.
CoolJade™ Comfort Liner: A removable, washable liner made of recycled jade fabric that actively creates a natural cooling effect, decreasing skin surface temperature up to $1 0^{\circ} F$ to maintain rider focus.
Focus Preservation: The combined ventilation and shell design forces perspiration across the rider's brow, away from their goggles, effectively preserving vision late in a race.
Enhanced Visibility: The Panoramic Goggle Port offers a wider opening, providing better goggle fitment, optimal sealing, and a massive field of view, enhancing rider safety.
Operational Safety: The MAGNEFUSION™ Cheek Pad Emergency Release System allows emergency responders to quickly and easily remove the cheek pads before removing the helmet post-impact.
