Arai VX Pro-4 Helmet

The iconic Arai VX Pro-3 receives its long-awaited replacement in the form of the Arai VX Pro 4 Helmet. The Arai VX Pro4 dirt helmet is for the serious off-road enthusiast, who requires nothing but the utmost in comfort and protection from their lid. The round shell shape is based on Arai's R75 Shape Concept and is optimized for strength and the peak, mouth vent and top vents are all designed to break away upon impact leaving less surface mass to catch or bind.

The interior Dry-Cool liner and cheek pads have been redesigned for comfort and ease of putting the helmet on and removing it, and feature Arai's signature triple-density foam construction. The eyeport is extremely wide and is large enough to accommodate even the largest goggles for a panoramic view of your surroundings. All the VX Pro vents have been redesigned, including an all new chin vent which has been moved to the outside of the helmet, which in turn makes the helmet roomier in the chin area. The other vents have been re-tooled as well, to provide increased airflow.

Helmet Shell:

  • cLc (complex Laminate construction) contains a specially designed composite fiber that is sandwiched between the two layers of Super Fiber Laminate. The composite fiber acts as a reinforcement layer without adding significantly to the weight of the helmet.

FCS (Facial Contour System):

  • To offer an even better snug fit and enhance the comfort to the lower jaw, the Facial Contour System (FCS) works with a foam spring support in the cheek pad that compresses and rebounds as you remove or put on the helmet.


  • Easy to clean diffusers create a strong venturi vacuum at the rear. Center top vent for increased airflow. Under-peak air intake collects en directs cool air into the helmet. Inner chin vent shutter prevents debris coming into the helmet in dusty riding conditions. Goggle ventilation and lower side vents.


  • The Arai peak scavenges and forces air into the forehead vent ports for cooling while at the same time using multiple relief-ports to reduce “lifting” at  higher speeds.

Dry-Cool Liner:

  • The completely removable and washable Dry-Cool interior lining is developed for and tested in MotoGP. It uses micro water cells to improve moisture and heat transfer from the head to the airflow and dries much faster than conventional textiles. Keeps your head cooler and dryer during a long ride.

The Arai VX Pro 4 Helmet is Snell- and DOT-rated.

Fantastic Lid Not cheap, but I actually forget I'm wearing it when out on the bike.. that's how good it is! (I did have to remove the breathe guard as it slightly touched my nose and made using goggles to snug) September 28, 2015
Great helmet! I bought this helmet after returning my first one due to the color being different in the pictures than in person. This new helmet is perfect! However, again the red turned out to be more of a hot pink/orange color. But it looks great on this helmet. Overall, perfect helmet! August 24, 2015
Great helmet, not the same color as pictures I bought this helmet as a gift for my boyfriend and he loved it! Arai is his favorite brand and the helmet is amazing. Delivery was great, the helmet arrived the next day! However, I bought the red tip to match his 4-wheeler and the red on the helmet does not look like the pictures. It was delivered as more of a neon orange looking color. We ended up returning the helmet in exchange for the same one with different graphics. Overall, Arai is a wonderful helmet but I was disappointed in the "red" color. August 3, 2015
comfort is second to none Great job Arai, the additional venting and other features on this new model have turned a great helmet into the perfect helmet. Thanks! April 13, 2015
this helmet is very light helmet fits great, and is very comfortable, and is very light November 19, 2014
Killer Helmet Been riding with this helmet for a week and a half and typical of Arai, a fantastic helmet. If your riding Enduro earplugs are necessary. Fit and finish are top notch. Oh and the "Red" is more of a fluoresce orange/red. October 10, 2014
