The Arai Quantic is a full-face sport-touring helmet built around the same principle that drives every Arai: protection before everything else. The outer shell uses Arai's Peripherally Belted e-Complex Laminate Construction (PB e-cLLC), a hand-laid composite construction that maintains structural integrity while achieving a meaningful reduction in weight compared to previous Arai touring helmets. Arai's characteristic smooth, round shell shape is not a styling choice: it is engineered to glance off and redirect impact forces rather than grip or snag, which also underpins the Quantic's ECE R22-06 homologation, the current highest international certification standard for motorcycle helmets.
Ventilation is one of the Quantic's strongest points, with 13 ports in total: 7 intakes and 6 exhausts working as a controlled system. Intake air enters through the 3D Arai logo duct, dual F1-derived tear duct top intakes, twin brow vents (an Arai exclusive), and a 3-position sliding chin vent. Hot air exits through the 3-way one-piece rear exhaust and spoiler, twin flush-fit side exhausts with foam dams to reduce wind noise, and a neck exhaust. The Variable Axis System (VAS-V) MAX vision visor provides a wide field of view and comes with a Pinlock insert lens included, keeping the visor clear in New Zealand's variable conditions. The visor also accepts an optional shield latch lever and PRO shade system.
Inside, the Quantic is trimmed with a premium brushed nylon liner that is fully removable and replaceable. The Facial Contour System (FCS) and 5mm peel-away temple pads allow a degree of fit adjustment to suit different head shapes, while replaceable cheek pads and ear cups let you dial in comfort over time. A neckroll wire pocket keeps intercom cabling managed, speaker pockets are built in, and the Emergency Release System (ERS) allows safe cheek pad removal in an emergency. The 5mm wider base makes getting the helmet on and off straightforward, and a removable chin cover and breath guard round out the comfort features.
If you ride long distances and want a helmet that earns its place on every kilometre, the Arai Quantic is a serious contender. ECE R22-06 certification, a proven glance-off shell design, and a 13-port ventilation system make it equally capable on a warm Northland run or a cold South Island crossing. The included Pinlock insert means the visor is fog-ready for New Zealand's variable weather straight from the box. For riders who want a handmade Japanese helmet with no compromises on protection or daily comfort, the Quantic is the touring lid to put on your head first.
1. Measurement
Measuring the head is a starting point for the entire sizing procedure. The circumference of the head should be measured at a point approximately two centimetres above the eyebrows in front and at a point in the back of the head that results in the largest possible measurement. Take several measurements to make sure you have the largest one.
2. Try On
Once you have determined your preliminary tape measurement, select the helmet that is closest to the tape measurement and try on the helmet. If it is between sizes, round up to the next largest one.
The correct procedure to put on the helmet:
If the helmet slides down on the head with no resistance, you have your first indication that it may be too large. If it will not slide down over the head at all it is too small. Many people unfamiliar with helmets are reluctant to pull down if they meet resistance as the helmet goes on, however if it is just snug going on, we recommend to get the helmet on. Only if the helmet is impossible to put on should you move up to the next size, as helmets that go on snug generally fit very well once all the way on. It is a fact that most people will select a helmet that is too large for them.
3. Horizontal and Vertical Movement Check
Once you are wearing the helmet, you should look carefully at the way it fits. Check to see if the cheek pads are in contact with the cheeks. Is there excess pressure on the cheeks? Look for gaps between the temples and the brow pad. Check the back of the helmet where the neck roll (if the helmet has one) makes contact with the neck. Does it touch at all? Or is it pushing the helmet away at the rear causing it to roll down over the eyes in front. After you have made your visual check, grab the helmet in your hands - one on either side - and while holding your head steady try to rotate the helmet from side to side. Note any movement of the skin while doing this, as well as the amount of resistance to movement. Next, check movement up and down, again noting skin movement and resistance. If in either test there was little or no skin movement, and/or the helmet moved very easily, the helmet is too large. A properly fitted helmet will cause the skin to move as the helmet moves. And, it will feel to the wearer as if evenly distributed pressure is being continuously exerted around the head.
NOTE: Helmets are a little like shoes, in that they do break-in a little. For this reason the best attitude to have when fitting is that the helmet should be as snug as you can stand to wear it.
4. Retention Check
This test may be a little uncomfortable, but it is very important to check. Fasten the chin strap tightly, hold your head steady, and grab the rear bottom edge with your fingers. Then try to roll the helmet off your head. If it comes off, it is undoubtedly too large. WARNING: Do not buy a helmet that can be rolled off the head with the strap fastened.
5. Pressure Point Check
Finally, unfasten the chin strap and remove the helmet. Immediately after the helmet has been removed, observe coloration of the skin of the forehead and cheeks. A reddening of the skin in a small area may indicate a pressure point. Pressure points sometimes are not noticed by the wearer for several minutes, or even hours later. They sometimes cause headaches, and are at the least, uncomfortable. If you notice a pressure point, but cannot remember experiencing discomfort there while wearing the helmet, put the helmet back on for a few minutes, paying particular attention to the anticipated pressure point. If you experience pressure point discomfort either time, go to the next larger size, repeating steps four and five.
