Finding the right size motorbike helmet
To determine the correct motorbike helmet size, we recommend measuring your head circumference in centimeters with a tape measure. Wrap the measuring tape around the fullest part of your head – this will be just above the ears and eyebrows for most – and take the measurement at the forehead.Colour | Black |
