Arai Quantum-X Full-Face Helmet — Steel, Red (Small)

The Arai Quantum-X is a round-oval street full-face built for riders whose heads are slightly wider than they are long, with Arai's smooth VAS shell and a quiet, comfortable interior.

Key details: full-face helmet, round-oval fit, PB-SCLC (Peripherally Belted Super Complex Laminate) shell, VAS-Max Vision shield with Pinlock® 120 MaxVision™ insert included.

Why riders pick it:

• Variable Axis System (VAS) lowers the visor pivot by about 24 mm for a smoother temple area that helps the shell glance off impacts.
• Larger VAS latch with de-mist position holds the shield securely closed.
• QVF 3-position intake and QVR exhaust ducts; side vents keep exhausting even when the top intake is closed.
• FCS® cheek pads cradle the face, ease on and off, and help block wind noise.
• Water-repellent ES chin cover installed to smooth airflow and cut noise from below.
