The Arai Quantic Diamond Black Helmet boasts a sleek and stylish design with advanced features to provide superior protection and comfort to the rider. The outer shell is constructed with PB e-cLc 4, and it has a Variable Axis System (VAS) that provides maximum protection to the head. The helmet is equipped with front ventilation, including a 3D Arai logo duct, dual intake, brow vents, and a three-position chin vent. The rear ventilation system includes a neck exhaust vent, side exhausts, and a one-piece rear exhaust with spoiler function for enhanced aerodynamics.

The helmet features a VAS Max Vision Visor with a De-Mist option, a new shield latch lever, and an optional PRO Shade System. A Pinlock insert lens is also included to prevent fogging on the visor. The interior of the helmet is lined with brushed nylon material that is replaceable and washable, and it also features speaker pockets and Arai’s Facial Contour System (FCS) for maximum comfort and fit. The helmet also has an Emergency Release System (ERS), a breath guard, a fixed chin cover, a 5mm wider base, and intercom accommodation.

Arai Measurement Advice: Start with measuring your head to get an idea of the size to look for: measure (in cm) the circumference across the forehead, above the eyes and ears and over the small bump at the back of the head, read the size where the tape joins.
