The brand new VX-Pro4 evolved from the much loved VX-Pro3 model. Years of experience can be found in this ultimate off-road helmet. The perfect choice for MX, enduro and off-road use. Just as found 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 is not a lack of creativity, but a commitment to maintaining the integrity of the shell with real world impact performance.
Shell Materials: In order to maximize performance, Arai 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 cLc (complex Laminate construction) method demands precise and time-consuming assembly by master craftsmen from many individual pieces. Even though the bare shell is not visible after paint and final assembly, each one exemplifies the experience and the dedication of the entire Arai family.
New Peak Design: The new VX-Pro4's peak is 14 mm longer 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 new peak have been made larger as well.
Shell Shape: The shell itself is consistently round and smooth, maintaining the R75 Shape concept in areas above the acknowledged test line. Here, the rounded chin-bar maintains the same compact shell length with the previous model, the VX-Pro3. The result is less protrusion, which has proven to be less likely to catch and dig-in during a spill.
Chin-Bar Vent Grill: Installed on the uniquely rounded chin-bar, the stainless mesh grill is now mounted from the outside under 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.
Goggle Strap Locator: The Goggle Strap Locator keeps the goggle strap in position even during aggressive, competitive riding. The new top rear duct center brace, together with the side port cowlings, also assist in keeping the strap in position on the side and back areas.
Air-Through Ducts: The new Air-Through construction of the top front vent and top rear vent covers as well as the side-port air ducts are designed to offer greatly improved ventilation efficiency, and are easier to clean and maintain than those on the previous VX-Pro3 model.
Removable Neckroll: The all-new removable neckroll allows easy and convenient cleaning of the helmet.
Emergency Cheekpad Release System: The revised Emergency Release Cheekpad System has the release tab repositioned and is easier to access by rescue staff.
Certifications: The Arai VX-Pro4 Helmet is SNELL and DOT approved.

1. Measure your head size. To do this, pass a tape measure horizontally around your head at a height of about one inch above your eye brows. When done properly, you will have measured the largest part of your head.
2. Check your measurement with the helmet sizing chart and select the closest size. As the helmet may not always meet your head size exactly, and your head measurement may fall between two sizes, first try the smaller size.
WHEN YOU RECEIVE YOUR HELMET
1. Expand the helmet opening by pulling outwards on each chinstrap, and slide your head into the helmet. If you are unfamiliar with helmets you may be reluctant to pull the helmet down, as it may feel too tight. Even if the helmet is difficult to put on, please use the smallest helmet possible. The helmet should feel snug. If the helmet is not tight, it is too big for you. New helmets will break in and loosen slightly over time.
2. Once the helmet is on:
Check that the helmet inner lining fits snugly all around your head.
Check that the top pad presses on the top of your head.
Check that the cheek pads press up against your cheeks. When you open and close your mouth, you should drag your teeth along the inside of your cheeks.
Check to make sure that you cannot easily slide your finger into the helmet along the side of your temple.
Hold the helmet with one hand on each side. Without moving your head, try to move the helmet up and down, and side to side. You should feel the skin of your head and face being pulled as you try to move the helmet. If you can move the helmet around easily, it is too big. Try a smaller size. Please note that during this check, the chinstraps should be properly fastened.
