Rider adjusting motorcycle helmet for proper fit

Updated: 14.05.25

A well-fitting motorcycle helmet is vital for safety and comfort on the road. An ill-fitting helmet can distract or fail to protect. This guide helps you measure your head, choose the right style, and ensure a snug fit. Explore our kids’ ride-on motorbikes for safe adventures!

1. How to Ensure a Proper Helmet Fit

Measure the largest part of your head (above ears and eyebrows) for a snug, comfortable fit. Helmets mold to your head over time, balancing safety and comfort.

2. Measuring Head Shape and Size

Head shapes vary (round oval, intermediate oval, long oval), impacting helmet fit.

  1. Use a Measuring Tape: Fabric tape is ideal.
  2. Measure Correctly: Place tape 0.5 inches above eyebrows, covering the fullest part.
  3. Check Twice: Repeat for accuracy and consult manufacturer sizing charts.

3. Choosing the Right Helmet Style

Match your helmet to your riding style for safety and comfort.

Helmet Type Features Best For
Full-Face Full coverage, visor, aerodynamic High-speed, touring
Open-Face Light, less coverage, good visibility City commuting, leisurely rides
Modular Flip-up front, versatile Touring, commuting
Half Minimal coverage, lightweight Short, low-speed rides
Dirt Bike Extended visor, ventilated Off-road, motocross

Ensure helmets meet DOT or Snell safety standards. Budget-friendly options can still be safe.

4. Trying On the Helmet

Try on helmets to ensure a snug, even grip without discomfort. No finger should fit between the helmet and forehead.

Comfort Liners: Swap cheek pads or liners for a custom fit.

5. Fit and Comfort Tests

  • Shake Test: Shake head side-to-side and up-down; the helmet should stay secure.
  • Pull Test: Pull from the back; it shouldn’t slide down.
  • Visual Check: Ensure it sits square, covering the forehead without tilting.
  • 30-Minute Test: Wear for 30 minutes to identify pressure points or discomfort.

6. Additional Fit Considerations

  • Glasses: Try helmets with glasses to ensure comfort without temple pressure.
  • Accessories: Account for Bluetooth headsets or GoPro mounts.
  • Fit Over Time: Snug helmets loosen slightly, ensuring long-term comfort.

7. Helmet Care and Maintenance

  • Cleaning: Use mild soap for the shell, fabric cleaner for liners. See how to clean a dirt bike helmet.
  • Inspection: Check for cracks, loose padding, or frayed straps before rides.
  • Storage: Keep in a cool, dry place away from sunlight.

8. Customizing Helmet Fit

  • Cheek Pads: Replace for better face snugness.
  • Liners: Swap for moisture-wicking or thicker options.
  • Straps: Adjust chin straps for a secure, comfortable fit; add covers if needed.

9. When to Replace Your Helmet

Replace helmets every 5–7 years or immediately after a crash, as materials degrade and impact compromises safety.

10. Warning Signs of Poor Fit

  • Pressure Points: Forehead or temple pressure indicates a tight fit.
  • Looseness: Gaps or movement during shaking suggest it’s too loose.
  • Strap Issues: Tight, loose, or irritating straps need adjustment or covers.
