Arai VX-Pro4 Stream Helmet
Description
The latest expression of the ultimate off-road helmet, the brand new VX-Pro4 evolved from the much-loved VX-Pro3 model. So it's still the perfect choice for MX, enduro, and off-road use. Just as in every Arai helmet, the basic and simple organic shell shape is based on the R75 shape concept. The absence of exaggerated edges or protrusions on the shell should not be mistaken for a lack of imagination. It's a visual demonstration of our commitment to maintaining the integrity of the shell with real-world impact performance.
A smooth instead of ridged shell
The shell itself is consistently round and smooth, maintaining the lancin Off shape concept in areas above the acknowledged test line and influencing those below the test line. Here, the rounded chin bar maintains the same compact shell length as the previous model, the VX-Pro3. The result is less protrusion, which may be less likely to catch and di in during a spill.
Shell material
In order to maximize performance, we precisely assemble the shell from multiple proprietary components. Super fiber, one of the primary materials, costs up to six times more than standard fiberglass but provides 30% higher tensile strength and increased penetration resistance. The PB-cLc (Peripherally Belted Complex Laminate Construction) method demands precise and time-consuming assembly by master crafts-men from many individual pieces.
Chin bar vent grill
Installed on the uniquely rounded chin bar, the stainless mesh rill is now mounted from the outside on the exterior vent cap and can be easily removed for cleaning or damage replacement. The vent cap is also designed to break away from the chin bar in the event of impact.
Rear Duct
The Air-Through top-rear-duct center brace also functions as a ole-strap locator. The diffusers can be removed or replaced quickly and easily by removing a single screw on the rear-duct center brace.
Improved peak
The peak is 14 mm loner and 5 mm wider than the previous model for improved ability to deflect roost and flying debris. To compensate for increased lift, the air outlets on the improved peak have been made larger as well. Made with durable, yet extremely flexible material, mounted with plastic screws designed to break on impact, so as not to snag on impact which could send energy into the helmet or cause excess rotational force.
Emergency release system
The revised Emergency Release Cheek Pad system has the release tab repositioned and is easier to access by rescue staff. Pioneered by Arai, the concept behind the emergency release cheek pad design was to allow trained medical personnel easier access to an injured rider, reducing the chance of unintentional injury.
Note: Fluorescent finishes used in certain models of Arai helmets are not covered by warranty and may fade with the passage of time and exposure to the elements.
For helmet sizing, wrap a tape measure around the widest part of your head. If you plan on wearing a balaclava or a skull cap, measure with the garment.
