The brand new Defiant. "For those who demand style, but refuse to compromise for it." A new benchmark in comfort, quiet, stability, and ventilation in a street helmet. The helmet you'd build if you wanted to treat yourself to a dream. Every feature optimized for the conditions, speeds and environment of the real world. A helmet for others' top-of-the-line models to envy.
Although much more aggressive on the outside, as compared to its siblings, the new Defiant contains all the internal attributes that set every Arai apart from the crowd. Just some of the exclusive Arai features: FCS, Multi-Density one-piece EPS liner, micro fitting interior padding, pull-down spoiler, Dry-Cool liner material.
The Defiant has an evolved version of Arai's very popular intermediate oval interior shape. Arai is the only company offering multiple interior-fit packages to better address the infinite variety of consumers' head shapes and sizes. Its interior fit shapes evolve and improve as company research recognizes trends based on consumer feedback. The Defiant shape is similar to the current Corsair-V and Vector models, and the former RX-7 Corsair and Quantum-2, but the Defiant's shape represents a further refinement of interior shape configuration based on market feedback and Arai's continual comparison, measurement, and research of human head shapes.
SAI Max-Vision Brow Vent Shield
The SAI MAX-Vision Brow Vent Shield continues the enhanced field of view of the SAI eye port (with 5mm more peripheral view at each side) with a full eye port cavity to accept the Pinlock 100% Max-Vision lens for larger anti-fog field of view. Clear Pinlock 100% Max-Vision Brow Vent anti-fog lens included with the helmet.
Hand-Formed Natural Shell Shape
The foundation of every Arai helmet is a basic and simple organic shell shape. A helmet is first and foremost an energy management system! From ventilation to aerodynamics, shield systems, radios, Bluetooth, and graphics-everything comes secondary, and none should ever interfere with the helmets number one job of impact energy management. Arai looks to the incredibly strong shape of an egg for inspiration. The smooth uninterrupted spherical shape that transfers stress loads more evenly across its entire surface.
Ventilation and aerodynamics are designed to work together to flow more air while reducing drag. The new IC-4 upper front intake vents have a slide-gate closure that seals more completely when closed, allowing for a cleaner airflow when closed. The new ACR-4 flow through exhaust vent also allows airflow to pass over and through the vent, accelerating exhaust flow from the helmet interior when open, and reducing drag when closed.
Micro-Fittable Removable Interior
Fully removable/replaceable/washable interior comfort head liner, cheek pads, chin strap covers, and neck roll pad. Cheek pads have a 5mm peel-away layer to assist with facial fit and comfort. The helmet comes standard with 5mm peel-away temple pads to add another level of customization, giving the helmet interior a little extra width when needed.
The new IR neck roll pad has an improved shape to flow more air to the bottom of the helmet at lower speeds and improve rider comfort. The new shape also makes it easier to put on and take off the Defiant, with less contact and pressure on the ears. New water repellent material along the bottom edge improves comfort for a dryer ride in wet conditions.
FCS Cheek Pads
The design of the new FCS cheek pads cannot be overemphasized. The contoured shape, combined with multiple layers of varying foam densities, supported by a patented spring, cradles the face like nothing that has ever come before-even in an Arai. The FCS cheek pads are gently, simultaneously holding the cheek and jawbone firmly for a secure fit, with gentle contact with the soft areas of the cheek for an incredible all day comfort without pressure. An added bonus of the FCS pads is the effect it has on lowering noise levels.
IR Front Spoiler Edge
The all new IR front spoiler edge trim creates a stabilizing down force, reducing buffeting, lifting, and wind noise that can be generated by the turbulence trapped between your shoulders and the bottom of the helmet.
Aerodynamic Exhaust Vent Cowling
New more aerodynamic upper and side exhaust vent cowling, sculpted to enhance stability while increasing exhaust efficiency. The side vent cowls are tailored to the needs and speeds of the street. Compared to the Corsair-V, the cowlings are larger and more aggressively styled, as lower street speeds require more surface area and a more refined shaping in order to deliver the increased stability. High speed performance is also excellent.
Arai's exceptional handmade craftsmanship, made to a higher standard of protection, comfort, and quality that's difficult to put a price on.
IR Chin Vent
The new IR chin vent offers more than simply an aggressive look, it also provides multiple functions with tangible benefits to the rider. Position 1 allows air to flow through the top port and up the inner surface of the shield for defogging. Position 2 allows air to flow through the bottom four ports to the mouth. The new design also allows for easy vent replacement.
Brow Vent Channeling
The faceshield brow vents, like those of the Corsair-V, redirect incoming air to the temples instead of the forehead, and around the ear area (missed by many helmet ventilation systems). The stale air is then exhausted out the side exhaust cowls. The airflow over the temple artery reportedly also helps cool the blood flow to the brain area. The simple re-purposing of the existing vent features greatly improves helmet performance and rider comfort.
