Arai Defiant-X Solid Helmet

You value independence. You are self-defining. What you believe in is Yours, and Yours alone. For riders looking to establish their own identity. The Defiant-X is Your self-defining helmet.

The Defiant-X has Arais INTERMEDIATE OVAL (IO) interior fit shape.

Peripheral Belt construction born from F1 technology. The PB-cLc shell features technology developed in the highest level of racing in the world: F1. The Defiant-X shell is constructed from the layering of many materials with proprietary adhesives which allow for a larger eye port. Protection is further enhanced by the Super Fiber Belt that strengthens the shell like the bands of a barrel. This distinct belt resists the widening of cracks encountered in an impact while evolving our most advanced shell in strength, weight, and protection.

To enhance the strong shell design, the open-close shutters are placed inside of the helmet. Air can flow over the mouth for a demist function by opening and closing these shutters.

To further enhance internal airflow, air channels originally designed for the Corsair-X were borrowed and updated and connected to new exhaust ports on the chin bar. This increased airflow reduces fogging potential and increases rider comfort.

When front duct are open, air flows freely into the helmet. When closed, the QVF-2 Duct prevents air from entering and functions as an exhaust duct, allowing hot air to be pulled from the helmet interior.

The upper QVR-2 rear duct has three vent holes controlled by a single sliding gate. When open, air is pulled from the helmet interior.Additional side and neckroll exhaust ports keep the back of the head comfortable by removing hot air as well.

Featuring anti-microbial material, using a low acidic fabric to help maintain a balanced pH level with the skin. It is also odor resistant helping the helmet stay fresher, longer in between cleanings.

Arais exclusive 5mm peel-away surface pads on both sides of the headliner and in the FCS Cheek Pads give you the option of 5mm more of interior width if needed (minimizing the need to purchase optional thickness pads). Yet another level of fit customization no other helmet brand offers.

This model accepts the optional Pro Shade System.

Happy with the helmet happier with the customer service and price
Great helmet at a great price. Fast shipping great company great experience. I had not heard of 2 wheel before I ordered this helmet. They were really great to deal with definitely reccomend. Fastest shipping I have gotten from anywhere.

Helmet is nice a little expensive and missing neck roll pull outs and honestly for a high end expensive helmet it should have them. The liner is not as plush as I expected but I think it may be because of the anti microbial properties. Definitely a good looking helmet and is comfortable and quiet. Happy with it for the price I paid. Thanks 2wheel I will definitely be ordering from them again. If they blow up they will give revzilla a run for there money. They even do cash rewards for purchases.
