Helmet Arai Quantum-ST PRO Fluo. The Quantum-ST PRO is characterized especially by the form of "elongated" because its length is a bit greater and the width is slightly less compared with the standard form of an Arai. The model Quantum-ST PRO improves the Quantum-ST in several respects: it incorporates visor outer solar system (PRO-Shade), more space in the area of the mouth and the nose compartment on the padded side to the speakers of an intercom and an innovative inner material (Eco-Pure). This is a helmet sport-touring that combines the technology of competition of the RX-7 GP with the level of comfort necessary for on-road driving throughout the day.


Outer shell ScLc (Super complex Laminate construction), which is 40% stronger than the fiber glass standard. The shell (the longest) and the inner form of the Quantum-ST PRO is designed especially for those riders whose helmets can cause a pain point in the front because the inner form has not been prepared taking into account the added length of the head.


The output of the rear air, one-piece, extracts the warm air and moist of the inside of the helmet and improves aerodynamics. The ventilation of the chin guard 3-position facilitates the removal of the fog of the screen and facilitates air fresh renovated. The side ports generate low pressure behind the rear opening to improve the extraction of hot air, reduce wind noise, and prevent the jerking at high speed. The air outlet of the collar of the neck and the vents front drive fresh air towards the frontal area and the temples.
