Shoei Helmet Size Comparison
Keep in mind that Shoei helmet size comparison with other brands isn’t always straightforward. Sizes can vary between manufacturers. Always rely on the Shoei-specific size chart and fitment guide, rather than assuming your size from another brand will be the same.
Evaluating the Shoei Helmet Fit
Once you receive your helmet, it’s important to check the fit. A helmet should feel snug but not uncomfortably tight. Here are some tests to perform:
-
The Forehead Test: With the helmet on, try to slide your fingers between your forehead and the helmet’s EPS liner. If you can easily fit more than one finger, the helmet is likely too big.
-
The Cheek Pad Test: The cheek pads should make contact with your cheeks. They should be snug, but not so tight that they cause discomfort or restrict your ability to talk.
-
The Roll-Off Test: Buckle the chin strap and tighten it properly. Try to roll the helmet off your head by pulling it from the back. If the helmet rolls off, it’s too big.
-
The Movement Test: While wearing the helmet and with the chin strap buckled, try to move the helmet from side to side and up and down. The helmet should move your head and skin together. If the helmet moves independently of your head, it’s too large.
-
The Pressure Point Test: Wear the helmet for at least 15-20 minutes. Check for any pressure points or areas of discomfort. Pressure points can become unbearable on long rides.
Shoei Helmet Fitment Guide

The chin strap should be snug against your throat, allowing you to breathe and speak comfortably. Finding your Shoei helmet size takes time and patience.
Fine-Tuning the Fit
Shoei helmets often come with adjustable cheek pads and liners, allowing you to customize the fit. Here’s how to adjust the fit:
-
Cheek Pads: Shoei offers different thickness cheek pads that can be purchased separately. If your cheek pads are too tight, you can replace them with thinner ones. If they are too loose, you can replace them with thicker ones.
-
Crown Liner: Similar to cheek pads, Shoei provides a variety of crown liners. If your helmet feels too tight on the top of your head, you can swap out the liner for a thinner option.
-
Chin Strap Adjustment: The chin strap should be adjusted so that it’s snug against your throat. There should be no slack in the strap. The strap should be centered and comfortable.

- Consult the Shoei helmet size chart for the specific model.
- Try on the helmet and check for a snug, comfortable fit.

Shoei Helmet Size Recommendations
Shoei helmet size recommendations are based on head circumference, but also consider head shape. Some people have more oval-shaped heads, while others have more round-shaped heads. If you find that a particular Shoei helmet model doesn’t fit well, it may be due to your head shape. In this case, try a different Shoei model or another brand that caters to your head shape.
Common Mistakes to Avoid
- Guessing Your Size: Never assume your helmet size based on previous helmets or other brands. Always measure your head and consult the Shoei size chart.
- Ignoring Pressure Points: Don’t ignore pressure points, even if they seem minor at first. They can become painful on long rides.
- Compromising on Fit: Don’t settle for a helmet that’s “close enough.” A properly fitted helmet is essential for safety and comfort.
- Not Trying Before Buying: Whenever possible, try on the helmet before you buy it. This allows you to check the fit and ensure comfort.
- Buying Used Helmets: Avoid buying used helmets, as they may have been damaged in a crash and their protective capabilities may be compromised.
What to Do If You’re Between Sizes
If your head measurement falls between two sizes on the Shoei helmet size chart, it’s generally recommended to choose the smaller size. This is because the helmet’s liner will compress over time, and a slightly snug fit will become more comfortable. You can always adjust the cheek pads and liners to fine-tune the fit.
The Importance of Professional Fitting
If you’re unsure about finding your Shoei helmet size or evaluating the fit, consider getting a professional helmet fitting. Many motorcycle dealerships and specialty stores offer this service. A professional fitter can accurately measure your head, assess your head shape, and recommend the best Shoei helmet model and size for you. They can also help you adjust the helmet for optimal comfort and protection.
Fathoming Shoei Helmet Care

- Cleaning: Clean the helmet’s exterior with a mild soap and water solution. Avoid using harsh chemicals or solvents, as they can damage the shell.
- Liner Maintenance: Removable helmet liners can be hand-washed with mild soap and water. Allow them to air dry completely before reinstalling them in the helmet.
- Storage: Store your helmet in a cool, dry place away from direct sunlight and extreme temperatures.
- Inspection: Regularly inspect your helmet for any signs of damage, such as cracks, dents, or loose parts. If you notice any damage, replace the helmet immediately.
