In 2011 the Arai XD-3 helmet was superceded by the new Arai XD-4 Helmet. XD means “Crossover Design” because it crosses over into so many riding styles. You can quickly and easily change it for adventure touring, dual-sport, supermoto competition, commuting, street riding, whatever. Visually, it looks like a dirt helmet, with its peak, uniquely-styled chin bar and the opening for goggles. But the Arai XD3 Helmet also has a full faceshield like a street helmet, a faceshield that easily slides up under the peak. You can remove the shield and/or the peak in no time, and then easily re-install either or both whenever you like.
Arai XD 3 Helmets have an "intermediate oval" shape. Intermediate oval refers to a shorter front-to-back and a little wider side-to-side design than the long oval. This neutral fit package should fit most head shapes well.
Arai XD-3 Helmet Features
Re-Designed Peak: One of the keys to the original XD’s uniqueness was Arai’s Twin-Cam Shield Pivot System that enables the shield to operate fully beneath the mounted peak without protruding. The shield stays low when it’s raised, allowing the peak to be mounted lower, resulting in better aerodynamics and a better appearance. The XD3 ’s peak has been re- designed for even better stability and airflow – and tested to perform up to street-legal speeds. The shield system is also designed for the shield to be used in combination with the peak, alone without the peak, or with the peak and no shield, as desired.
Rounded Chin bar: Like the Arai VX Pro Series, the XD3 has a unique rounded chin bar shape with less protrusion, making it potentially less likely than a sharply-pointed chin bar to catch and dig in during a spill. The oval form is based on the egg, long known for its extremely-strong and efficient, natural shape. See page 7 for more details on Arai’s important Organic Shell Shape design philosophy.
Ventilation: The Arai XD3 ’s ventilation combines the best of both worlds, with a total of 5 intake and 7 exhaust vents. Its features include Arai’s diffuser ventilation design first introduced on the RX-7 series road racing helmets – and now arguably Arai’s most copied feature. It also uses the front vents from our Profle model, again designed for increased air intake, while retaining the original XD’s mouth-vent system that can either provide fresh air around the mouth area, or direct the air upward along the interior surface of the faceshield to help prevent fogging. There are vent controls both inside and outside the chin vent. Additionally, exhaust vents on the lower left and right sides and in the lower neck-roll draw out more hot air from inside the helmet.
Emergency Cheek-Pad Release System: Yet another Arai innovation, first introduced on the VX-Pro3 dirt helmet. From Arai’s decades-long commitment to rider safety comes the first Emergency Cheek-Pad Release Design created specifically for motorcycle helmets. Developed to allow easier access to an injured rider, the XD3 ’s cheek-pads slide out easily via the integrated pull- tabs built into the underside of the cheek-pad - which makes helmet removal much easier for trained medical technicians.
