Arai Defiant Helmet
The Arai Defiant is an exciting addition to the world-class Arai helmet lineup. From conception to production, this Arai was made with tourers, cruisers, and naked bike riders in mind; to deliver aerodynamics and venting that significantly reduce turbulence, noise, and buffeting in an upright riding position. The Defiant takes its place alongside Arai’s RX-Q, with its same unmatched street performance and safety features, but the Defiant delivers an even more comfortable and quiet ride for the rest of us.
The Defiant’s ventilation system provides maximum airflow when riding upright, while Arai’s newly designed intake and exhaust vents minimize drag and noise when vents are open and closed. Like the RX-Q, Signet-Q, and Corsair V, the Defiant’s shield features brow vents that channel air down to the temples and around the ears. Brow vents provide airflow through the front of the helmet and do not require cutting vents through the forehead of the shell. Such vent cutting weakens a key impact area of the shell and is something that Arai will never do.
Like its Arai siblings, the keystone of each handmade Defiant is Arai’s uncompromising, proprietary R75 aerospace fiberglass shell. The distinctive R75 shell design achieves the pinnacle of real world rider protection, and is built on foundational strength, roundness, and smoothness. These core principles are fundamental to the way Arai has developed helmets since the beginning, and they act together to divert full impact forces and efficiently disperse those remaining. The round Arai shell, furthermore, has a low center of gravity that reduces fatigue and contributes to the incredible comfort enjoyed by Arai riders.
The Defiant comes stock with a Pinlock® shield and Pinlock® visor. Usually an optional upgrade, Pinlock® is considered by many to be the most straightforward and comprehensive fog solution available. It works by trapping a small amount of air between your visor and the thin Pinlock insert.
