Choosing the correct size helmet
Helmet fit is critical to helmet protective performance. The correct helmet size can only be checked and confirmed by physically fitting the helmet to the user. Always try the helmet on before purchasing it, to be sure you are purchasing the correct sized helmet for you.
Head measurement instructions
Wrap a flexible tape measure around your head approximately one inch above the eyebrows and ears. Use this measurement (in either inches or centimeters) to find your helmet size.
Helmet sizing information
To achieve proper helmet fitment, begin by finding your head circumference size using the method described above. Remember that the helmet size you choose should fit around the crown of your head comfortably with no pressure points. The cheekpads should fit firmly around your face. Once your chin strap is fastened, grab the chin bar of the helmet and move it side to side. Your cheeks should move with the helmet, which should not slide across your face. Different thickness cheekpads can be purchased from Pistonoids to obtain the best fit.
Let’s face it, Icon® helmets look cool and you want to keep them that way. We’ve found the following methods work really well to keep our helmets looking sharp and ready to roll. Remember, never use gas, pre-mix, carb cleaner, brake cleaner or any other random unlabeled spray can lying around the garage. Chemicals and harsh solvents can break down the materials in your helmet; it’s like using brake cleaner to polish your plastics—don’t do it!Interior Cleaning
- Remove interior lining as shown on page 10 of the User Manual.
- Soak your interior in a mild solution of baby shampoo.
- Rinse in clean water several times until all soap is gone.
- Let interior air dry and replace accordingly.
* Never machine wash or dry your helmet interior.
Your helmet is equipped with a scratch resistant fog free shield. Common household cleaners such as glass cleaners, surface cleaners, and furniture cleaners, can leave behind unwanted residues, or in some extreme cases damage the shield itself. It is our recommendation the same steps outlined above for cleaning the exterior of your helmet should be applied to cleaning the exterior of your shield. Use no cleaners or detergents on the inside of your shield. Using anything other than a clean soft cloth, micro fiber cloth, or the bag supplied with your helmet, will ruin or reduce the effectiveness of the fog free coating.Storage
It is a good idea to protect your helmet if it is stored for a period of time. Store your helmet inside the helmet bag we have provided in a secure, dry place out of direct exposure to sunlight.Exterior Cleaning (Gloss Helmets)
- Lay a warm, wet, cloth towel on the exterior of the helmet for at least 5 minutes to soften dried on bugs. (Don't skip this step!)
- Using a fresh, wet, clean cloth and mild dish soap wipe down the exterior to get ride of road grime and softened bug guts.
- Use another fresh dry cloth towel to dry the helmet and get rid of any water spots.
Exterior Cleaning (Rubatone Helmets)
- Lay a warm, wet, cloth towel on the exterior of the helmet for at least 5 minutes to soften dried on bugs.
- Remove the now softened bugs and road grime with a light blotting action. For this use the soft part of your helmet bag provided or a clean microfiber cloth. * Never rub aggressively with anything on the Rubatone™ or you can ruin the finish.
- For gloss helmet finishes, use spray automotive wax that is specifically designed for cars with a clear coat. (Available at any automotive store.)
- For matte finishes, you know better than to polish a matte finish don’t you?
One Impact Rule - Any helmet that has sustained an impact should be replaced. Helmets are designed to absorb only one impact. The helmet is designed to absorb some shock by partial destruction of the shell and liner. After your helmet has endured any impact, the impact absorption liner portion of your helmet will have dispersed the energy from that impact, thus rendering the liner compacted and, therefore, compromised. This damage may not be visible. Even if there is no VISIBLE damage to the shell, the helmet’s usefulness is expired after one impact. A helmet that has experienced an impact should be destroyed and replaced, even if it is apparently undamaged. Obsolesence and Helmet Disposal - A helmet has a limited lifespan in use and should be replaced when it shows obvious signs of wear, e.g. change of fit, cracks, rust, fraying or other signs of normal “wear and tear” that can contribute to helmet degradation.
