How to Choose a Motorcycle Helmet: Fit, Safety Ratings and Types
Your helmet is the single most important piece of riding gear. The right one is snug, certified and comfortable enough that you’ll actually wear it on every ride.
Start with certification
In the US, helmets sold for road use must meet DOT (FMVSS 218). Many riders also look for Snell or ECE 22.06 ratings, which involve independent or additional testing. Look for the certification stickers and labels rather than trusting a product listing alone. Be wary of very cheap “novelty” helmets, which are not legal or safe for road use.
Pick the right type
- Full-face: most coverage, quieter and best protection for the chin and face.
- Modular: flip-up chin bar; handy for touring and commuting, usually heavier.
- Open-face (3/4): lighter and airier, but leaves the face exposed.
- Dual-sport / adventure: peak and larger eyeport for off-road use, with a road-friendly chin bar.
Get the fit right
- Measure your head circumference about an inch above your eyebrows and compare with the brand’s size chart. Sizing varies between brands.
- A helmet should feel snug all round, with no pressure points or gaps. Cheek pads should press on your cheeks so your skin moves when you move the helmet.
- With the strap fastened, try to roll the helmet forward off your head. It shouldn’t come off.
- Wear it for 10–15 minutes before deciding. Hot spots that seem minor get worse on long rides.
Head shape (round, intermediate or long oval) matters as much as size, so if one brand always squeezes your forehead, try another.
Features worth paying for
- A pinlock-ready or anti-fog visor for cold-weather riding.
- Good ventilation you can operate with gloves on.
- A double-D ring or micro-lock strap, which is secure and easy to use.
- A built-in sun visor, if you ride into low sun often.
When to replace it
Replace a helmet after any significant impact, even if it looks fine, and generally every five years or so as liners and padding degrade. Check the manufacturer’s guidance for your model.
