Arai Quantum-X Solid Motorcycle Helmet - Diamond White/X-Large

The Quantum-X is purpose-built for the street, setting a new benchmark in comfort, quiet, stability, and ventilation. Arai has applied its tireless 24-7 focus, typically devoted to their race helmets, to designing, refining, and adapting proven concepts to this new purpose. The Quantum series has always been the "go-to" choice for those with a rounder head shape. The new Quantum-X brings back that same shape in a feature-rich package.

The round oval shell is designed for head shapes with an even balance between length and width. It features a quick-release lever for the side pod and faceshield, along with a clear anti-fog Pinlock insert for all-season visibility. Additionally, the QVF and QVR upper ventilation ducts offer more adjustment and better flow-through performance. The Quantum-X is DOT approved and meets the FMVSS 218 Standard. The ES chin cover increases exhaust from the mouth area while reducing wind noise. It is also compatible with the VAS-V Pro Shade system and is SNELL-2020 approved.

Overall, the Quantum-X is a helmet that combines comfort, quietness, stability, and ventilation in a way that is both innovative and practical. With its thoughtful design and attention to detail, it proves to be a reliable choice for riders with a rounder head shape, offering a high level of performance and convenience for a variety of street riding situations.
