The Arai Quantum-X Competition Helmet is the ideal helmet for riders with a more round head shape thanks to its balanced length and additional width. 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. 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. If you're looking for new high performance helmet at an affordable price point, look no further than the Arai Quantum-X Competition Helmet!
