Motorcycle Helmet Sizes: Getting It Right
Please establish your correct motorcycle helmet size prior to ordering. Motorbike crash helmets in particular can be problematic when purchased blind online. Sizing is extremely subjective and varies between brands and sometimes even between models within the same brand. Consequently, we can only supply helmets on a non-returnable basis and we strongly advise you to try on and establish your correct size for the helmet model in question. We have our own shop premises where you can come and do this but to avoid a possible wasted journey (if there ever is such a thing on a bike), please phone in advance to arrange an appointment and to ensure we have your preferred choice in stock. Whilst such a returns policy may seem harsh, this does protect you, the consumer, from the possibility of buying a returned helmet that may have been dropped by the previous customer. We hope you understand. Thanks.

Choosing the right helmet is very important. The helmet must fit properly to give you the best protection if you fall off or are involved in an accident. Here’s how to choose a helmet that fits properly:
Step 1: Measure your head size
Step 2: Ascertain the right helmet size
Step 3: Check that the helmet fits properly
1. MEASURING YOUR HEAD SIZE
Measure your head size by placing a flexible measuring tape around your head approximately one finger’s width (2 cm) above the eyebrows. This will give you the greatest circumference of your head. The measured value represents your head size in centimetres.
2. ASCERTAINING THE RIGHT HELMET SIZE
Refer your head measurement to the tables above to find the helmet size that should fit you.
3. CHECKING THAT THE HELMET FITS PROPERLY
With the helmet on and the chinstrap fastened and properly adjusted (important: for chinstrap adjustment, see Section D.9. “Retention system”), check whether the helmet is the right size for you and fits properly.
Step 1: Check that all pads of the interior lining press firmly against your head without being uncomfortable:
a) Top centre pads
b) Cheek pads
c) Headband padding (especially in forehead area).
If the pressure is uncomfortable or possibly even painful, try the next size up.
Step 2: Check that the helmet gives you an adequate peripheral field of vision. Lateral limitation of vision is normal with any helmet due to its design but it should not feel distracting or unduly restrict your vision.
Step 3: Hold both sides of the helmet firmly with your hands and move the helmet up and down. Try also to rotate the helmet. You should be able to feel the helmet moving your head and the surface of your face. If it is too easy to move the helmet, it is too large! Try a smaller size.
Step 4: With the helmet on, take hold of the chin section of the helmet and try removing the helmet from your head in a backwards direction. If you can do that, the helmet is too large or the chinstrap adjusted too loosely. For your own safety, use a smaller size or re-adjust the chinstrap as necessary.
Step 5: With the helmet on, hold the back of the helmet with both hands and try tipping the helmet forwards over your head. If you can remove the helmet this way, either the chinstrap is adjusted too loosely or the helmet is too large. Re-adjust the chinstrap or choose a smaller helmet.
Repeat these steps until you have found the right helmet size that fits roperly.
Caution: Never ride with a helmet that doesn’t fit properly!
