What's this?

Arai Quantum X Helmet

The Quantum X has a lot to live up to given the reputation which follows the long time classic RX-Q. Luckily, Arai is not one to skimp and has again improved upon a helmet which has lived on the top tier for many years. The Quantum X helmet brings back the widely loved fit of the RX-Q, which features a balanced shape with a little extra room on the sides, making it a great fit for those with a slightly more round headshape. If you have a more intermediate oval headshape, you can simply install a Corsair X head liner to convert the Quantum X into a slightly longer fit.

VAS Shield System:

Normally the shield mounting position must remain relatively high, because a lower shield pivot will not allow the shield to open or close. The VAS (Variable Axis System) has a variable axis (moving pivot point). This allows shield opening and closing even with the 24mm lower shield mount position, compared to the RX-Q.

VAS Shield Latch System:

VAS shield latch system captures and holds the shield closed more securely to help prevent unexpected opening. In addition to a de-mist position, the larger latch design allows for an intuitive and seamless operation of the shield.

PB-SCLC Shell:

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.

Eco Pure Liner:

The fully removable interior liner system is made from Eco Pure material, which helps maintain neutral acidity levels close to human skin and antibacterial consumption, as well as a softer liner material and adjustable temple padding to allow for a customized fit.

VAS V MV Shield:

The VAS MAX Vision shield is standard to provide better visibility in all seasons and for all types of riding and comes standard with a clear anti-fog Pinlock insert.

Additional Features:

  • VAS (Variable Axis System) shield and side pods are exclusive to the Arai Quantum X Helmet
  • Dual function lever releases both the side pod and the face shield for quick and simple face shield removal
  • VAS shield latch system captures and holds the face shield closed and provides a de-mist position to slightly crack the shield open
  • VAS MAX Vision face shield provides excellent visibility in all seasons thanks to the included Pinlock insert
  • Neckroll is removable and has additional exhaust channels to remove interior heat
  • Cheek pads have the Emergency Release Tab feature
  • QVF & QVR upper ventilation ducts look familiar but offer more adjustment and better flow through performance
  • PB -SCLC Shell has superb tensile strength due to a variety of carefully-positioned materials and light weight resin
  • Includes clear Pinlock insert
  • Snell 2015 and DOT approved
