Arai Quantum-ST Helmet - Puro White

As it is an Arai helmet, you can take joy in the fact that safety and protection will have been in the front of the designers mind throughout all stages of development of this helmet. It is based on the old Quantum, but has a new outer shell that is longer front to back, giving the rider a lot more room around the chin. It has the same strengthening band as the RX-7 GP, but a completely new ventilation system. As most Arai helmets do, the Quantum ST has a removable and washable liner with an emegency cheek pad removal system.
