Bell MAG-10 Rally ULTRA WW Carbon Fiber SA2025 Helmet

The Bell MAG-10 Rally ULTRA WW Carbon Fiber SA2025 Helmet combines an ultra-lightweight carbon composite shell with Bell's advanced ZeroNoise wired and wireless communications technology to create a premium open-face helmet specifically engineered for rally drivers and co-drivers.

Based on technology developed for Bell's HP10 Rally platform, the MAG-10 Rally ULTRA WW delivers professional-level protection, excellent sound insulation, integrated communications, a removable carbon Half Chin Bar, adjustable carbon peak, and integrated dark smoked sunscreen in a lightweight, modern package.

Certified to both Snell SA2025 and FIA 8859-2024, the MAG-10 Rally ULTRA WW is built for competitors who demand advanced safety and communication performance without compromising comfort or weight.

Integrated ZeroNoise Wired and Wireless Communications

The defining feature of the MAG-10 Rally ULTRA WW is Bell's integrated ZeroNoise WW communication system.

Rather than relying on bulky external communication modules, the ZeroNoise electronics are integrated directly into the helmet. The system provides professional-quality wired communication inside the vehicle while also providing wireless connectivity for communication outside the car.

The WW system is designed to transition between wired and wireless operation while maintaining a clean, purpose-built rally communication setup for drivers and co-drivers.

Adaptive Noise Cancelling Technology

Rally cars are extremely loud environments, making effective sound isolation and clear communication essential. The ZeroNoise WW system incorporates adaptive noise cancelling technology designed to improve wired communications in demanding motorsport environments.

High-performance speakers, a noise-cancelling microphone, sound-insulating ear muffs, and integrated electronics work together to improve voice clarity while reducing unwanted background noise.

Heavy-Duty Integrated Nexus Connector

The MAG-10 Rally ULTRA WW features an ultra-reliable in-molded Female Nexus connector integrated into the helmet.

This design creates a clean connection point for compatible rally amplifiers and intercom systems while minimizing loose wiring around the helmet.

A detachable right-side cover allows the Nexus connector to integrate smoothly into the shell. Bell also supplies a flat right-side cover for racers who prefer to use a straight cable exiting the helmet instead of the integrated connector.

Ultra-Lightweight Carbon Composite Shell

The MAG-10 Rally ULTRA WW uses Bell's premium carbon composite shell to provide an exceptional combination of lightweight construction, strength, and impact protection.

Reducing helmet weight can help decrease neck fatigue during long rally stages, high-G driving, and extended competition while maintaining the protection required by current FIA and Snell standards.

Snell SA2025 and FIA 8859-2024 Certified

The Bell MAG-10 Rally ULTRA WW is dual-certified to the latest Snell SA2025 and FIA 8859-2024 motorsport helmet standards.

This dual homologation makes the helmet an excellent choice for professional and amateur rally competitors competing under sanctioning bodies that recognize these standards.

Always verify the helmet requirements of your specific series or racing organization before competition.

Fast Removable Carbon Half Chin Bar

The MAG-10 Rally ULTRA WW features Bell's Fast Removable Half Chin Bar (HCB).

The lightweight carbon HCB provides additional lower-face coverage while retaining the visibility and accessibility of an open-face rally helmet.

In an emergency, the Half Chin Bar can be quickly detached to provide improved access to the driver's airway without requiring immediate helmet removal.

Adjustable Carbon Fiber Rally Peak

An adjustable carbon-fiber sun peak allows drivers and co-drivers to customize their field of view depending on changing lighting and rally conditions.

The peak can be repositioned to help manage glare from direct sunlight while preserving the broad visibility that makes open-face helmets popular in rally competition.

Integrated Dark Smoked Sunscreen

Bell incorporates an adjustable M10 dark smoked sunscreen directly into the MAG-10 Rally ULTRA WW.

The anti-scratch sunscreen provides additional eye protection from bright sunlight and glare without requiring the driver to change eyewear or install a separate external visor.

Additional adjustable sunscreen colors are available separately for racers who want to further customize visibility for different conditions.

Advanced Multi-Density Impact Liner

Inside the carbon shell, Bell uses an advanced multi-density, multi-piece liner engineered to maximize energy absorption and impact performance.

The combination of the premium shell and advanced liner construction is designed to provide high-level protection while maintaining the comfortable professional fit expected from Bell's ULTRA helmet range.

Sound-Insulating Ear Muffs and Integrated Cheek Pads

The MAG-10 Rally ULTRA WW incorporates flexible sound-insulating ear muffs designed to improve comfort while reducing surrounding cockpit noise.

Integrated multi-density cheek pads use advanced materials to provide a secure and comfortable fit during long stages and demanding race conditions.

Factory-Installed HANS Anchors

Factory-installed HANS anchors are included as original equipment, allowing the helmet to be used with compatible head-and-neck restraint systems without requiring separate anchor installation.

Bell MAG-10 Rally ULTRA WW Helmet Sizing & Fit

Proper helmet fit is essential for both protection and comfort. Measure your head before ordering rather than selecting a helmet size based solely on the size you wear in another brand.

Use a flexible measuring tape and measure horizontally around the widest portion of your head, approximately one inch above your eyebrows and around the largest point at the back of your head.

Keep the tape level and snug without pulling it excessively tight. Take the measurement two or three times and use the largest measurement when comparing your head size to the Bell helmet sizing chart.

A properly fitted racing helmet should feel firm and evenly snug around your head without uncomfortable pressure points. The helmet should remain securely positioned when you move your head.
