The Twin-Cam Shield Pivot System on the Arai<special id="4"/> XD helmet allows the faceshield to operate fully under a peak that can be lowered for better aerodynamics. Its high-flow peak channels air directly into the front vents. Dual TDF3 top intake vents and Double Delta bridged exhaust vents are designed to draw a significant volume of air from the helmet interior. The shell, constructed of fiberglass composite, is stronger and lighter and allows the use of softer, less dense liner materials for increased rider comfort. An efficient chinbar vent, with interior and exterior controls, flows fresh air to the mouth area or across the shield interior to help prevent fogging, while large chinbar side exhaust vents draw out additional hot air. Arai XD series helmets can be configured with shield and peak, peak only, for use with goggles, or shield only..
Fully removable, replaceable and washable liner. Optional liner sizes available for a custom fit. Four top vents. Meets or exceeds Snell and D.O.T. standards.

ARAI
Arai’s founder, Hirotake Arai, was originally a hat maker and a hard-core motorcycle enthusiast.
Back in the 1950s when Mr. Arai was a young man riding his motorcycle, there were no helmet manufacturers in Japan. And as Japan was a closed market, it was very difficult to obtain a proper helmet. Knowing the risks of riding motorcycles firsthand, Mr. Arai knew he wanted a good helmet for his own protection.
Arai is still a small, family-owned company driven by the same mission through three generations—three generations of riders. We at Arai are motorcycle enthusiasts. We ride. We build each Arai helmet as if we’re creating it for one of our own—a brother, a father, a husband, a mother, a sister.
