Improving on the revolutionary XC-Ram, the new CT-Z enhances the riding experience by offering the benefits of a peak / shield combination, with the flexibility of choice. The new CT-Z: Yet another example of Arai's decades-long tradition of the improving on what works, not simply change for the sake of unproven change. Arai changes are functional. The design intent has always been singular and unbroken: a better helmet with better protection and performance for the riders who choose it.

The CT-Z presents a major improvement: nothing short of redefining how open-face helmets can look-and protect. The most telling feature is the extended coverage in the lower jaw-cheekpad area-extending 1-3/16" forward compared to its previous - and traditional - open face helmets. The look itself is advanced, and it provides options that allow the helmet to better suit each rider's unique requirements. But like everything Arai does, the primary objective is to build a better helmet.

Technically, that means providing a measure of lower-jaw protection that's been missing from previous open-face helmets that leave that part of the face exposed.

  • Adjustable peak: Offers just the right amount of protection from the sun for just about any rider for those long rides heading directly into the sun.
  • The Dual Pivot shield mechanism allows the shield to "flip up" and under the peak at a low angle; this allows for a very low profile peak, reducing drag or "bucketing" at higher speeds.
  • Upper Vent System: borrowed directly from the Corsair-V, improving the airflow and stability even further; DF-11 diffusers have larger vent toggles for easier operation.
  • New fixed Air-Wing®: reduces lifting while providing additional stability at highway speeds.
  • New FCS™ cheek pad: New design is more similar to the full face helmet style; with a full-coverage EPS base and removable covers. This offers more support over a wider area, which allows for superior stability and comfort with minimal pressure, which might otherwise cause discomfort. And, like its full coverage counterpart, the FCS™ cheek pad comes standard with a 5 mm peel-away that allows for you to microfit your helmet to your facial structure.
  • Dry Cool® liner: Fully removable Dry Cool® liner, with removable surface pads from both sides of the headliner. This allows you to fully customize the fit of the CT-Z, without the purchase of additional padding.
  • Vented neck roll: Takes advantage of the existing airflow from around the riders neck to further enhance helmet ventilation by extracting more heat buildup from interior.
  • Ventilation: Front TDF-2 intake vents and the DDL-4 exhaust vent are a direct take off from the RX-Q. Side Cowl exhausts complete the ventilation upgrade.
  • Intermediate Oval: All open face helmets have Arai's Intermediate Oval (IO) shell shape. This shape is designed for the rider whose head has a front-to-back dimension that is longer than the side-to-side dimension.
  • Meets or exceeds SNELL and DOT standards.

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.
