no helmet can protect the wearer against all unforeseeable high and low-speed impacts. however, to help maximise head protection, the helmet must fit properly, and the retention system must be securely fastened under the chin. failure to ride with a proper fitting helmet and securely fastened chinstrap is dangerous, as the helmet could come off during an accident, resulting in severe head trauma or death.

how to measure:

  • to determine where you fall on the generic helmet sizing chart (as a starting point for proper helmet fit), pass a soft, flexible tape measure horizontally around your head at a height of approximately one inch (2.5cm) above your eyebrows (the largest measurement around your forehead).
  • select the helmet size
    who is closest to your head measurement from the sizing guidelines above. if your head measurement falls between two helmets, first try on the smaller of the two helmets.

your helmet is the single most important piece of safety gear.  when ordering your helmet, you are going to need to have an accurate measurmeent of your head.

use a tape cloth to measure (in cm) the circumference across the forehead, about 1 inch above the eyes and ears and over the small bump at the back of the head as illustrated, read the size where the tape joins.

please note these measurements are only a guide; sizing may vary between brands and models.
