Arai Signet-Q Diamond White Motorcycle Helmet
Arai Signet-Q Diamond White Motorcycle Helmet
The Arai Signet-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 Signet-Q's architecture stands out cleanly against it: the IC Duct intakes with top-mounted diffusers, the DDL-4 rear exhausts and the shaped side exhaust cowls. 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 Signet-Q is Arai's Long Oval Q-series helmet, exclusive to North America, developed for riders who get a forehead hotspot in intermediate shells. In simple terms it is an elongated RX-Q, adding 5mm front to back to make room for a true Long Oval interior. It uses Arai's ScLC (Super Complex Laminate Construction) shell, the Super AdSis LRS shield system with a DeMistLok latch, and Arai's diffuser ventilation with IC Duct intakes and top-mounted diffusers. The interior features Arai's FCS cheek pads with a 5mm peel-away custom-fit layer and emergency-release tabs, 5mm peel-away side temple pads, a removable and washable liner with optional sizes, and a Free Flow System exhaust. DOT and Snell M2010 certified, made in Japan. Note: Snell M2010 has been superseded by newer Snell standards; this helmet carries the certification current at the time it was built.

Specs & Features
- Long Oval Interior Shape
Designed for riders with longer front-to-back head shapes to reduce forehead hot spots common in rounder interior helmets.
- PB-cLc Shell Construction
Peripherally Belted Complex Laminate Construction utilizes Super Fiber and proprietary reinforcing materials to create a strong, lightweight shell engineered to maintain structural integrity and enhance glancing-off performance.
- Hyper-Ridge Reinforcement Band
Reinforcement band around the lower shell increases strength and lowers the helmet’s center of gravity while allowing a larger bottom opening for easier on and off.
- One-Piece Multi-Density EPS Liner
Multi-density liner uses varying foam densities in a single piece to help manage impact energy while maintaining a compact shell profile.
- SAI Shield System (Super AdSis I)
Wide eye port design for improved peripheral vision with tool-less shield removal and installation.
- Pinlock® Ready Shield
Compatible with SAI Max Vision Pinlock inserts for enhanced anti-fog performance (insert sold separately).
- Brow Vent Face Shield System
Integrated brow vents channel cooling air to the temple area without compromising shell strength.
- Facial Contour System (FCS®) Cheek Pads
Multi-density foam supported by a spring system cradles the face securely while improving comfort and wind noise management.
- 5mm Peel-Away Custom Fit Pads
Peel-away layers in the cheek pads and temple area allow micro-adjustments for a more personalized interior fit.
- Dry-Cool® Interior Liner
Moisture-wicking interior material helps keep the rider cooler and more comfortable during extended rides.
- Fully Removable / Replaceable Interior
Removable, washable liner, cheek pads, and neck roll for easy maintenance.
- Chin Vent with Internal Shutter
Closable chin vent directs airflow toward the face or shield depending on riding conditions.

Designed to assist trained emergency responders with safer helmet removal if needed.
