Choosing the right size is one of the most important parts of buying a motorcycle helmet. Use the guide below to measure your head and compare your measurement with the appropriate Hedon size chart.
Measure around the widest part of your head, approximately 2cm above your eyebrows, passing just above your ears and around the back of your head.
Use a soft tape measure and record the measurement in centimetres.

If you're between sizes or unsure which helmet is right for you, we're always happy to help.
Your head shape can affect how a helmet fits, even when the circumference measurement is correct.
Hedon helmet models suit slightly different head shapes, so use the illustration below alongside the individual size charts.

The Hedon Heroine Racer 2.0 Bauhaus is a handcrafted full-face motorcycle helmet cleverly inspired by the Bauhaus movement, where form and function were designed to work together. Clean lines, geometric shapes and carefully balanced colour bring that influence into one of the most distinctive designs in the Heroine Racer collection.
Designed and developed in London, the Heroine Racer 2.0 combines an ultra-lightweight, low-profile composite carbon-fibre shell with modern ECE 22.06 protection. A wide field of view and three-channel ventilation system make this a helmet designed to be ridden, not simply admired.
Inside, Hed Armour 360° cushioning, Merlin antibacterial fabric and brown leather lining create the close, comfortable interior Hedon is known for. The updated four-position visor mechanism lets you adjust the visor in stages, giving you more control over airflow as conditions change.
The Heroine Racer Bauhaus brings art, design and motorcycle engineering together, translating the movement’s distinctive geometry, colour and functional approach into a modern full-face motorcycle helmet that remains unmistakably Hedon.
Bauhaus is even better in person than it looks online. The geometric design wraps around the shell, so the balance of shape and colour changes as you view it from different angles, something photographs don’t quite capture. Add the lightweight, low-profile shell, Hedon’s soundproofing and modern ECE 22.06 protection, and it’s a beautifully considered helmet that’s built to be ridden, not just admired.
