LS2 Helmet Size Chart: Find Your Perfect Fit

Choosing the right helmet size is crucial for safety and comfort. LS2 Helmets are designed to provide a snug fit that ensures optimal protection without compromising comfort. Use this guide to measure your head accurately and select the appropriate helmet size.

How to Measure Your Head for an LS2 Helmet

1. Prepare a Measuring Tool: Use a soft, flexible tape measure or a piece of string that you can later measure against a ruler.

2. Position the Tape: Place the tape measure approximately 1 inch (2.5 cm) above your eyebrows, wrapping it around the widest part of your head, just above the ears and around the back of your skull.

3. Measure Multiple Times: To ensure accuracy, take the measurement several times and use the largest measurement obtained.

4. Determine Your Size: Refer to the size chart below to find the helmet size that corresponds to your head circumference. If your measurement falls between two sizes, it's recommended to choose the larger size for a more comfortable fit.

Tips for Ensuring a Proper Helmet Fit

• Snug Fit: The helmet should fit snugly all around your head without causing pressure points.

• Cheek Pads: They should touch your cheeks without pressing uncomfortably.

• Movement Test: With the chin strap fastened, try moving the helmet side to side and up and down. Your skin should move with the helmet, and it should not shift independently.

• Vision: Your eyes should be centered in the eye-port, and the top of the helmet should not obstruct your vision.

• Break-In Period: Helmets may feel slightly tight initially but will conform to your head shape after a short break-in period.

Italian-built and racing-proven, Airoh has spent decades engineering helmets that balance featherlight shells with serious impact protection. Whether you're carving a mountain pass on a Airoh street bike helmet, hitting motocross whoops in an Aviator, or pulling dual-duty on an adventure ride, getting the right size is the first step to performance and safety. Use the chart below to dial in your fit before you order from BTO Sports.

Airoh helmets are sized by head circumference in centimeters, so grab a soft tape measure and follow the steps below. If you fall between two sizes, Airoh recommends going up — a helmet that's too tight will create pressure points on a long ride.

How to Measure for an Airoh Helmet

Head circumference: Wrap a soft tape measure around the widest part of your head, about a half inch above your eyebrows in front and around the fullest point at the back, just above your ears.

Measure multiple times: Take two or three passes to make sure you're not pulling the tape too tight or too loose.

Round up, not down: If your measurement falls between two sizes, step up to the larger shell. Airoh's removable cheek pads let you fine-tune the interior fit.

Check for hot spots: A properly sized helmet should feel snug and even across your forehead, temples, and crown — with no single pressure point.

Every Airoh helmet, from the Aviator 3 and Commander 2 to the Wraaap, Matryx, Strycker, and Connor, uses the same unisex adult head-circumference sizing. Match your measurement (in centimeters) to the size below.

Why Proper Airoh Helmet Sizing Matters

A helmet is only as protective as its fit. An Airoh helmet that's too loose can shift on impact and fail to distribute crash forces the way the shell was engineered to. One that's too tight creates pressure points, cuts circulation, and turns a long dirt bike or touring day into a headache. Dialing in the right shell size — then fine-tuning with Airoh's removable liners and cheek pads — is the fastest way to turn a good helmet into a great one. It's also why every rider should revisit their sizing hub when upgrading gear.

If you're also building out the rest of your kit, pair your new Airoh lid with the right protective gear and goggles from our dirt bike gear lineup.
