Arai Quantum St Pro Motorcycle Helmets are designed primarily for road and touring use. Arai’s philosophy of producing the most protective, comfortable and durable helmets are very much evident in this new shell. The Arai Quantum ST Pro is fitted with an outer sun visor system that will not compromise shell integrity, Emergency Tab Release System which is identical to that used in GP and World Superbikes and the latest eco pure removable interior to name just a few.
