Xd4 Motorcycle Helmet White

Xd4 Motorcycle Helmet White
XD4 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, whatever. Visually, it looks like a dirt helmet, with its peak, protruding chin bar and the opening for goggles. But the XD4 Series also has a full face shield like a street helmet, a face shield that easily slides up under the peak. And you can remove the shield and/or the peak in no time, and then easily re-install either or both whenever you like. Arai is taking you to the next level with the XD4. High-flow peak channels air directly into the front vents. Twin-cam Shield Pivot System allows the face shield to operate fully under a peak that can be lowered for better aerodynamics. Fully removable/replaceable and washable liner. 4 top vents. Dual Intake/Dual Exhaust Ventilation - dual 1/C top intake vent and Double Delta bridged exhaust vents designed to draw significant volumes of air from helmet interior. CLC (Complex Laminate Construction) shell - fiberglass composite is stronger and lighter - allows use of softer, less-dense liner materials inside for increased rider comfort. Efficient chinbar vent (with interior and exterior controls) flows fresh air to the mouth area or across the shield interior to help prevent fogging. Large chinbar side exhaust vents draw out additional hot air. Meets or exceeds Snell and D.O.T. standards. For proper fit and size measure the circumference of your head 1 above your eyebrows and around the largest portion of the back of your head. 22 1/2 - 22 7/8 ----Medium 23 1/4 - 23 5/8 ----Large 24 - 24 3/8 --------X-Large 24 3/4 - 25 1/8 ----XX-Large
