Motorcycle Helmet Size & Fit Guide

Measure first, brand second

Measure head circumference with a soft tape about 2 cm above the brows. Brand charts (e.g. 55–56 cm = S) are a start; the same ‘M’ fits differently across brands.

Wear the helmet 10–15 minutes in the shop. Cheeks should feel snug without forehead hot spots. ‘Comfortably loose’ slides in a crash.

Fit test: four checks

With the strap on, tip your head forward while someone tries to roll the helmet up; it should move with your skull. Turning your head should drag cheek pads, not spin on the crown.

• No gap / ‘spinning’ feel between forehead and EPS
• Cheek pressure when talking, without cutting breath
• Strap snug without crushing the throat
• Visor edge not cutting your view

Full face, modular, open face

Full face is the default for chin protection on street and road. Modular is convenient with hinge and weight trade-offs. Open face is weak on wind and debris; keep it for low-speed short hops in heat if you must.

Standards and lifespan

Read ECE 22.06 (or your region’s current standard), DOT, or Snell labels. Uncertified ‘cheap copies’ are a risk.

After any impact, the helmet is done even without a visible crack. Typical life is 5–7 years as EPS and pads age; follow the maker.

Used helmets?

Usually no. Impact history is unknown, liners are personal, and hygiene is a gamble. A new entry-level certified lid beats a used ‘premium’ unknown.
