  • Arai threw limitations out the window and developed the RX-Q helmet to bring you quality and comfort unmatched in any of today's street bike helmets.
  • The Arai RX-Q helmet is formed by hand to better match the natural shell shape. This design gives the RX-Q helmet more stability at street speed and minimizes the negative aerodynamic effect when turning your head.
  • Experience told Arai that not all head shapes are created equal, so they designed the RX-Q helmet to match the Intermediate Oval (IO) shape. The IO shape is best suited for most people with dimensions greater front to back then side to side.
  • Super Complex Laminate Construction make up the shell of the RX-Q, which consists of a proprietary aerospace fiberglass developed by Arai.
  • Arai gave the RX-Q helmet a wider peripheral eyeport, also found on the elite Corsair V helmet.
  • Where others skimp, Arai built the RX-Q helmet without cutting corners by adding the Hyper-Ridge Band and vent at the bottom to increase thickness and safety through durability.
  • Inside the Arai RX-Q helmet is a multi-density single piece EPS liner that optimizes energy dispersion.
  • Keeping you cool came with research. Arai found that re-directing the brow vents to channel fresh air to the temples and ear pockets decreases the temperature of blood flow to the brain.
  • Fresh air easily finds its way through the advanced ventilation on the RX-Q helmet with properly placed and sized vents.
  • A removable and cleanable vented neckroll adds customized protection to the RX-Q helmet.
  • Arai developed the emergency cheekpad release system found on the RX-Q helmet. If the helmet should ever need to be removed in an emergency the cheekpads can be taken out before the helmet is removed to reduce injury.
  • Wearing the RX-Q all day will go without problem, thanks to Arai's cozy liner that cradles the head rather then creating a pressure fit.
  • Lower road noise is achieved from the redesign of the cheekpads that create a better seal between the RX-Q helmet and your face.
  • To further lower noise coming from the road or motorcycle Arai added sound-deadening foam in the ear pocket of the RX-Q helmet.
  • Keeping your Arai RX-Q lid clean is simple with the removable and washable liner.
  • Arai developed the easy to use LRS shield removal that does not require tools to remove the shield for cleaning or replacement.
  • Side pods remain on the RX-Q helmet, as well as their other helmets, for a greater purpose then a clean look. The side pods continue the round shape and eliminate flat spots that could be less effective at dissipating impact energy.
  • Meets or exceeds D.O.T. and SNELL standards

Love Arai x10 years!

This is my Second Arai Helmet. First helmet was an RX-7 Corsair Harada. Crashed bad (I literally was rolling up and down the side of a mountain, frame broke in two separate places), thanks to the helmet (and other gear), I survived to ride again.

The RX line is awesome. Just like their predecessors, the RX-7 Corsair. Can't think of anything bad to say about Arai quality, fit, and style. The same quality as the Corsair V. Differences between the two are 1.) ventilation system (since the RX-Q is specifically made for the street, it provides better ventilation for stop and go riding.) With that being said, I don't ride on the track, nor have I used the Corsair V. But for $200 less then the Corsair V, that was the decision maker for me. 2.) The RX-Q vents aren't painted to match the helmet as opposed to the Corsair V. They are dark smoke plastic. But that's minor and the color is just about aesthetics. The RX-Q and Corsair V do share the same face shields and padding.
I have an XS and fit is perfect.

Of note, the only other helmets I have used are low end HJC's. So I can't really compare mid to high end helmets made by Shoei, AGV, Suomy, HJC, Scorpion and others.

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.


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.
