Arai Quantum-X Solid Adult Motorcycle Helmet - Diamond Black/Medium

The Quantum-X is a purpose-built helmet designed for the street, delivering a new benchmark in comfort, quiet, stability, and ventilation. Arai has applied the same tireless 24-7 focus devoted to their race helmets to the development of this model, refining and adapting proven concepts to a new purpose.

The Quantum series has long been the "go-to" helmet of choice for those on the rounder end of the head shape spectrum. The new Quantum-X brings that iconic shape back in a feature-rich package.

The round oval shell is designed to accommodate head shapes with an even balance between length and width. A quick-release lever allows for easy removal and re-attachment of the side pod and face shield. A clear anti-fog Pinlock insert ensures all-season visibility, while the QVF and QVR upper ventilation ducts offer more adjustment and better flow-through performance.

The Quantum-X is DOT Approved, meeting the FMVSS 218 Standard. An ES chin cover increases exhaust from the mouth area while reducing wind noise. The helmet is also compatible with the VAS-V Pro Shade system, providing additional protection and customization options.

Arai's commitment to quality and safety is evident in the Quantum-X, with the brand's unwavering focus on delivering a superior riding experience. The result is a helmet that not only looks the part but also delivers exceptional performance, ensuring the rider's comfort and protection on the road.

Whether you're a seasoned rider or new to the sport, the Quantum-X offers a compelling blend of style, functionality, and safety that is sure to make it a standout choice in the world of motorcycle helmets.
