Before purchasing ANY helmet, please read this page carefully:

Motorcycle riding has special personal hazards and no helmet can protect the head against all foreseeable high speed and low speed impacts. The protective capability of a helmet is difficult to measure at the time of purchase because there are untold number of accidents. A helmet can provide protection only to the extent that your head is covered with the helmet. However, the use of a well fitted, securely fastened helmet can minimize the risk of death or permanent impairment from head injury. For maximum head protection, the helmet must be of proper fit and the retention system must be securely fastened under the chin. Failure to have a proper fit and to securely fasten the helmet is dangerous as the helmet could come off in an accident resulting in severe head injury or death.


Before purchasing a helmet, please follow Step A all the way through Step D below carefully.

Although we offer a world-leading range of sizes and shapes, the final is always yours.

If any helmet, by any manufacturer, doesn't feel like it fits you properly, or doesn't meets your needs:
Keep looking!
It's more important to us that you feel safely protected, than it is to sell you a helmet.

 To determine proper fit:
1. Measure your head size. Pass a tape measure horizontally around your head at a height of about one inch (2.5cm) above your eyebrows that results in the largest measurement.
2. Select the helmet that is closest to your head size using this sizing chart.
In some cases, the helmet may not always exactly meet your head size. If your measurement falls between two sizes, try on the smaller size first.
Try the helmet on:
1. Expand the helmet opening with your hands, (see Diagram A) and slide your head into the helmet. Pull the chin-straps only, not the chin strap covers. Pulling on the covers may rip them. If the helmet is not tight, it is too big for you. If you are unfamiliar with helmets you may be reluctant to pull down the helmet, which should feel tight. Even if you feel it is difficult to put it on, please use the smallest helmet possible. You should feel a snug fit.

Check for a proper fit:
With the helmet on, go through the following checklist to determine whether the helmet is the correct size.
1. Check whether the helmet inner lining fits snugly all around your head.
2. Check whether the top pad presses closely on the top of your head.
3. Check whether the cheekpads are in contact with your cheeks.
4. Check to make sure there is no space around your brow under the inner lining, where you can insert your fingers.
5. Now, take hold of the helmet with a 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.
Check the retention system:
1. Fasten the chin strap as tight as possible without causing you pain (see diagram B). There must be no slack in the strap and it must be tight up against your chin.
2. With the chin strap secured, put your hands flat on the back of the helmet and try to push the helmet off by rotating it forward.
3. Next, put your hands on the front of the helmet above your forehead (or on the chin guard) and try to push the helmet off by rotating it toward the rear.
4. If the helmet starts to come off in either direction, do not use the helmet. Either the helmet is too large for you or the chin strap is not tightened enough.
REPEAT ALL OF THE ABOVE STEPS UNTIL YOU HAVE A PROPER FIT AND THE HELMET IS SECURELY FASTENED.
Tightening the chin strap correctly is extremely important. Try to pull down on the chin strap with the tips of your fingers - if the strap is not up against your chin or loosens, you have not properly put the strap through the D rings. Start again (see Diagram B). If your chin strap is loose, the shock of an impact may knock your helmet off, leaving your head completely unprotected. Do not use a helmet that can be rolled off the head with the chin strap fastened, since it may come off in an accident, resulting in death or serious personal injuries.
D Ring:
To securely fasten the D ring retention system, thread the end of the chinstrap through the D rings only as shown in diagram B and pull it tight against your throat. Clip the chin strap end hook on to the D ring as shown in diagram B to secure the loose end of the chin strap after securely fastening the chin strap. The only function of the chin strap end hook fitted on the end of the chin strap is to avoid fluttering of the end part of the chin strap.
