Arai Helmet (Europe) B.V.


The new Quantum ST is the successor to the popular Quantum model. Aimed and developed for the large group of serious sport-touring riders who demand a perfect mix between touring comfort and sports performance. The new Quantum ST is the perfect companion for these riders. Using the technology from our top of the range RX-7 GP race helmet in combination with a brand new outer shell, a new dimension in sport-touring performance was achieved. The new ST shell offers significantly more space around the chin area for even more comfort and ventilation during those long runs.

Another Arai breakthrough in advanced helmet technology is FCS, the abbreviation of “Facial Contour System”. The FCS cheek pads offer an integrated ‘’spring’’ action. This makes putting the helmet on easier with less effort needed. With FCS the cheek pad wraps under the jawbone and on the cheekbones instead of mostly on the soft cheek area. Although the fit feels looser, FCS actually offers secure support over a larger area providing superior stability and comfort with minimal pressure. The new “Peel Away” pads offer thin surface pads that can be removed from the headliner as well as the top surface of booth cheek pads to achieve the best possible, personal fit and minimize the need to purchase additional padding.

Together with the Dry Cool interior, extensive ventilation system with dual intake, exhaust and side vents the new Quantum ST offers new levels in touring comfort. Of course the Pinlock anti fog insert lens, Max Vision SAI visor and the Arai Emergency Release System are standard features.

Finally we are proud to mention that the new Quantum ST meets both the ECE 22-05 and SNELL M2010 standard! A special feature that was previously only reserved for the RX-7 RC and RX-7 GP.

Available sizes: XS-XXL
