Arai Quantum ST Pro Helmets Guide
Arai Quantum ST Pro Helmets from GetGeared
The new and improved sport tour helmet, the Quantum ST Pro range includes the popular Quantum ST Pro Team. It is the latest limited edition graphic in the Arai helmet range and is the successor to the popular Arai Quantum model. The Arai Quantum ST has been developed using the technology from Arai's top of the range RX7 GP race helmet in combination with a brand new outer shell. The new ST shell offers significantly more space around the chin area for even more comfort and ventilation during long rides. 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 thin surface pads in the headliner as well as the top surface of both cheek pads can be removed to achieve the best possible helmet fit and minimize the need to purchase additional padding. With the Dry Cool interior, extensive ventilation system with dual intake, exhaust and side vents the new Quantum ST offers high levels of touring comfort. Of course the Pinlock anti fog insert lens, Max Vision SAI visor and the Arai Emergency Release System are standard features. However, the new Quantum ST helmet meets both the ECE 22-05 and SNELL M2010 standard, a special feature that was previously only reserved for the RX7 RC and RX7 GP helmets.
