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 headshape 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 headshape.
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.
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 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.
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.
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.
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.
