What's this?

Arai Quantum X Helmet

The name Arai has been synonymous with quality and protective technologies since the beginning of their days and the Quantum X continues to push the bounds, proving why Arai stands at the top. The Quantum series has been the go to helmet for riders with a more round head shape and this stays true with the Quantum X, thanks to its balanced length and slight additional width. With the simple installation of a Corsair X head liner, the Quantum X can even be converted to fit those with an intermediate oval head shape.

The Arai Quantum X Motorcycle Helmet features a chin curtain that helps to block air intrusion from the turbulent air underneath the helmet, as well as increases negative pressure to enhance the exhaust ventilation performance. The interior lining includes Arai's signature 5mm peel away ear pocket padding and ear pocket recess to accommodate communicator speakers.

PB SCLC Shell:

  • Peripherally Belted - Super Complex Laminate Construction shell
  • Design combines multiple materials and techniques created internally by Arai that deliver both performance and affordability
  • Shell has superb tensile strength due to a variety of carefully-positioned materials and light weight resin

VAS Shield System:

  • VAS (Variable Axis System) shield and side pods are exclusive to the Arai Corsair X Helmet
  • Variable axis (moving pivot point) allows shield mount position to be lower than most helmets
  • 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 securely
  • Provides a de-mist position to slightly crack the shield open
  • Larger latch design allows for intuitive and seamless operation

VAS V MV Shield:

  • VAS MAX Vision face shield
  • Provides excellent visibility in all seasons
  • Includes clear anti-fog Pinlock insert

Ventilation:

  • QVF and QVR upper ventilation ducts offer adjustment and airflow performance
  • Vents are easy to operate with gloved hands

Arai's Proprietary Liner:

  • Fully removable and soft interior liner and cheek pads
  • Made from odor-resistant material which helps maintain neutral acidity levels close to human skin
  • Adjustable temple padding to allow for a customized fit
  • Neckroll is removable and has additional exhaust channels to remove interior heat

Safety:

  • Snell 2020 and DOT approved
  • Cheek pads have the Emergency Release Tab feature
