Ensuring that your helmet fits correctly is essential if you're planning to ride a motorbike.
The first step is to measure the circumference of your head. This can be done by using either a measuring tape or a piece of string.
The tape measure should rest just above your eyebrows and ears, measuring the fullest part of your head.
The next step is to compare the measurement to our sizing chart (below), and ensure you order the correct size.
Once your have your helmet, it should initially feel very snug on your head. In particular, you should notice that your cheeks feel pinched together, and the helmet doesn't slide across your head when you look from left to right.
The helmet padding will gradually begin to loosen over some time, as the helmet moulds around your head shape.
