The Arai RX-Q in Diamond White is a plain white with no graphic, carrying a fine pearl flake that gives the surface depth in direct light rather than reading as a flat solid. The RX-Q's architecture stands out cleanly against it: the DDL-4 rear exhaust, the shaped side exhaust cowls and the wide eye port. Brand new and never worn (new old stock), this helmet comes exactly as received, fully preserved in its original packaging with all included accessories.
The RX-Q was Arai's Intermediate Oval street flagship of the Q generation, positioned by Arai as the ultimate street helmet. It uses the S-cLc (Super Complex Laminate Construction) shell, Super AdSis I shield system with DeMistLok, IC Duct intakes with top-mounted diffusers, DDL-4 rear exhausts, and side cowl vents tuned for real-world street speeds. The brow vent airflow is ducted across the temples and out through the side cowls, and the eye port is 5mm wider on each side than the previous generation. Inside are FCS cheek pads with 5mm peel-away layers and emergency-release tabs, a Dry-Cool fully removable, washable liner in optional sizes, and a Free Flow System lower exhaust. DOT and Snell certified for its production era — verify against the interior label — made in Japan.
