The ‘X’ range of helmets by Arai is one of the brand’s most versatile lines. If you’re on the market for an everyday helmet, there’s a good chance the Quantum-X fits the bill. On a regular day, you can expect the Arai Quantum-X Box Helmet to go for over $800, but today it’s on sale at 40 percent off at $500.
The $800-plus price is definitely warranted. The SNELL and DOT approved helmet has all the ventilation you could ever want on a hot day’s ride, but when the temperatures drop the optional neckroll, cheek pads and chin curtain not only seal in vital warmth, they help give the helmet a true custom fit. The Quantum does, however, have a particular shape which better fits riders with rounder heads. But if you’re deadset on the Quantum-X and have a narrower noggin, you can install a Corsair X headliner.
