The Formula Helmet is the absolute in total head protection. The Adaptive Impact System (AIS) is a high-performance ecosystem of structural design and energy mitigating materials. Each layer of the AIS from RHEON enhanced Energy Cells, to the dual-density EPS liner, and the 12k carbon fiber shell, was carefully fine-tuned to achieve the goal of creating the highest performing helmet possible.

Fly Racing are serious about rider safety and have incorporated the Formula helmet with many safety features, some never before seen on a motocross helmet. A 12K carbon fiber shell, dual density EPS liner with Conehead technology and Fly's own Active Impact System featuring RHEON enhanced energy cells, this is the best helmet that Fly has ever produced.

Invented by Dr. Dan Plant, RHEON is impact energy cells that maximize absorption of low speed linear and rotational impacts. The unique shape and maze-like structure allow them to compress and shear. This slight movement maximizes absorption of low-speed and rotational impacts, reducing overall stress on the brain. RHEON's adaptive chemistry reacts instinctively to absorb energy depending on the severity or direction of an impact.

The Formula helmet incorporates lower density expanded volume EPS in critical zones of the helmet. This provides improved suspension for impacts. Combined with conehead technology that absorbs and dissipates impact forces more effectively than traditional helmets. Conehead technology provides a more progressive absorption of energy and which is why the Formula has six critical zones outfitted with this technology.

Carbon fiber makes the Formula helmet extremely lightweight while being resilient to penetration, thanks to the 12K carbon fiber.


  • ECE/DOT approved
  • 12k carbon fiber shell produces an extremely lightweight (~2.8lbs) shell with superior penetration resistance
  • Impact Energy Cells help to maximize absorption of low speed rotational impacts to the brain
  • Strategic areas of the helmet have more impact absorbing EPS
  • The clavicle shell relief zone creates a soft area filled with EPS & EPP to reduce collar bone injuries
  • Integrated nose guard
  • Interior comfort liner and cheek pads are made of a washable, moisture wicking, anti-microbial material
  • Premium helmet garage included with purchase

      To ensure that the proper sized item arrives, we suggest customers follow brand specific sizing guides. Google and other search engines provide a wealth of information in regards to specific brands sizing. Just because you currently wear a certain size, a new brand may have slightly different fitment specifications. Please reach out to us if you have any questions regarding the fitment of the brands we carry and we can provide you with more accurate sizing charts on a brand-by-brand basis. 1-877-745-4232

      As well please use SIZING CHART here.

      In order for a helmet to protect properly and be the most comfortable, it must be sized to your head correctly.

      The best way to check sizing is to put the helmet on and see that the helmet feels snug equally all around your head. The helmet should not feel too tight or too loose at any particular point around your head.

      If you can’t put it on, at all, then that’s obviously too tight. If you can get it on, but it hurts where it presses against your head, that’s also too tight. If it’s snug all around, too snug to chew gum, that’s about right. Don’t forget about that 15 percent to 20 percent break-in that will occur.
