Why riders pick it
- Round Oval interior shape, shorter front to back and a little wider side to side than Intermediate Oval
- VAS shield system lowers the pivot point by an average of 24mm for a smoother temple area
- VAS latch holds the shield closed, with a de-mist function
- VAS Max Vision shield with a Pinlock-120 lens in the box, ready to install
- QVF three-position intake and QVR exhaust ducts; a side vent keeps exhausting even with the front shutter closed
- FCS cheek pads use layered foam on a foam spring for easier on and off and less wind noise
- Water repellent ES chin cover comes installed and reduces wind noise from below
- Odor resistant liner stays fresher between cleanings
- PB-SCLC shell combines multiple materials and techniques developed by Arai

Details
The Quantum-X is Arai's purpose-built street helmet for riders with a rounder head. If most helmets pinch the sides of your head while leaving room front to back, this is the Arai to try. This one wears the Steel graphic.
It uses Arai's Round Oval interior, which Arai describes as shorter front to back and a little wider side to side than its standard Intermediate Oval. The FCS cheek pads, layered foam on a foam spring, make it easier to get on and off and help block wind noise, and the liner is odor resistant.
The VAS Max Vision shield comes with a Pinlock-120 lens in the box, so it is fog ready from the first ride. Up top, the QVF three-position intake and QVR exhaust ducts move air through the shell, and a side vent keeps exhausting even when the front shutter is closed. The water repellent ES chin cover comes installed to smooth airflow and cut wind noise from below.
The shell is Arai's PB-SCLC construction. DOT and Snell M2020 certified. Long, narrow head instead? The Signet-X is the same idea in Arai's Long Oval shape.
