Purpose-built for the street. A new benchmark in comfort, quiet, stability and ventilation. Arai applied the same tireless 24-7 focus devoted to their race helmets to designing it, refining and adapting proven concepts to a new purpose. On the rounder end of the head shape spectrum, the Quantum series has always been the "go-to" helmet of choice. The new Quantum-X brings that shape back in a feature rich package.
The Quantum-X has Arai's Round Oval (RO) interior fit shape. Shorter front-to-back and a little wider side-to-side (as compared to Intermediate Oval).
The Variable Axis System shield mechanism was developed to enhance the shape of the shell, but the easy-to-learn changing mechanism is what most people are raving about. Quick, easy and intuitive.
The new Peripherally Belted - Super Complex Laminate Construction shell design combines multiple materials and techniques created internally by Arai that deliver both performance and affordability.
In keeping with the "improve on what works" mentality at Arai, the new QVF and QVR upper ventilation ducts look familiar but offer more adjustment and better flow-through performance.
The new water-repellent ES Chincover comes installed on the Quantum-X.
Enhancing the egg shape of the helmet, the cover smooths airflow, increases exhaust from the mouth area and reduces wind noise coming up from below.
Good for both cold and warm weather riding and is easy to remove and reinstall as needed.
The anti-microbial liner material on the Quantum-X resists the build up of bacteria and as a result allows your helmet to stay fresher, longer, between cleanings.
VAS-MV Pinlock Anti-Fog Lens:
The Quantum-X comes with the VAS-MV (Max Vision) shield that accepts the new VAS-MV Pinlock lens.
The new Pinlock-120 lens comes with the helmet in the box and ready to install.
Compatible with the VAS-V Pro Shade system (sold separately).
DOT and SNELL 2015 certified.
Note: Fluorescent and/or bright finishes fade over time and exposure to sunlight. This is normal and is not covered by warranty.
