Fitment Guide
How Your Helmet Should Fit
Why Proper Fitment Matters
The performance and safety of your helmet depend on a correct fit. A properly fitted helmet should remain securely positioned, provide consistent contact around the head, and not move freely.
Checking The Fit
- The inner lining should feel snug around the top and sides of your head.
- The top pad should press gently on the crown of your head.
- Cheek pads should firmly contact your cheeks where applicable.
- You should not be able to easily slip two fingers between your temple and the helmet.
Movement Test
- Buckle the chin strap.
- Hold the helmet firmly on each side.
- Move it side-to-side and up-and-down.
- The helmet should move your skin rather than slide freely.
Signs It May Be Too Big
- The helmet slides on with very little resistance.
- It feels loose around the crown.
- It shifts independently when you move your head.
- It can be moved significantly without pulling the skin.
Signs It May Be Too Small
- The helmet is extremely difficult to put on.
- You experience immediate concentrated pressure points.
- You experience sharp pain rather than normal snug pressure.
- Pressure remains excessive after allowing a reasonable fit check.
Correct Fit
- The helmet requires some effort to slide on.
- It feels snug around the crown without sharp pain.
- The helmet remains securely positioned.
- It does not move freely or independently from your head.
Sizing Disclaimer
Online sizing is a recommended starting point only. Sizing may vary by helmet model, head shape, hairstyle, head wraps, comfort preference, and break-in. Do not base your Daytona Helmet size solely on another brand, another helmet style, or a different Daytona model. Always confirm final fit before riding.
