HJC helmets are tested in the laboratory as well as in "real-life" to meet the highest quality standards. HJC is one of the very few helmet companies equipped with its own state-of-the-art wind tunnel laboratory to test aerodynamics, ventilation, noise, and more. The HJC wind tunnel test lab measures the air forces in a variety of riding conditions to improve helmet performance.

HJC's helmets, along with our technology, have added experience in designing the MotoGP race helmets to have the best technology in aerodynamics and ventilation and related fields. HJC's helmets provide the airiest helmets on the market. Experience the best performance with your HJC helmet.
Only use approved methods to clean the helmet. Using other unapproved chemicals or methods may damage the helmet shell or lining. A damaged helmet may increase your risk of serious injury or death in an accident.
Glossy Finish: HJC recommends cleaning your helmet with products designed for automotive cleaning and polishing. All HJC helmets are finished with an automotive type base coat/clear coat finish. Rubbing compounds can be used for deep cleaning to remove many scratches and scuffs. Follow the product’s instructions diligently. Over polishing with rubbing compounds can cause light abrasions which may dull the finish of your helmet. Stickers and decals will leave adhesive residue when removed. To remove the adhesive residue, use alcohol swabs. Be certain to immediately wipe away the excess liquid and clean the area with soap and water once the adhesive residue is removed. Do not use excessive pressure while rubbing when attempting to remove the adhesive residue, instead use multiple light treatments.
Non-Glossy Finish: For our flat finish (non-glossy) helmets, we recommend using warm water and mild soap. Use multiple treatments for heavier dirt. Do not use excessive pressure or rubbing compounds while cleaning the surface as a “glossy” effect could be created, ruining the flat finish appearance.
Although we recommend changing a helmet every 3 to 5 years, the accumulation of sweat, humidity, and dirt can deteriorate the fabric and stitching and this may cause odor. To wash HJC removable pads, HJC recommends regular machine washing and air drying.
For non-removable interiors, HJC recommends using bacteria and mildew eliminating products such as “Helmet Fresh”.
Dirt and debris can find its way into the venting of your HJC helmet. Compressed air cans used for cleaning computer keyboards may be used to blow the debris from the ventilation system. It is recommended that you remove any removable pads before doing this process.
Use of replacement parts not manufactured by HJC may increase your risk of serious injury or death in an accident. Only use HJC parts that are specifically designed to work with this helmet.
Your HJC helmet is designed to meet SNELL and DOT standards. Contact HJC America for more information about SNELL and DOT standards. Modifying your helmet may increase your risk of serious injury or death in an accident. Do not modify your HJC helmet. Modifications include the following:
drilling holes;
cutting shell, liner, or strap;
modifying the retention system, including adding a chin cup;
removing parts;
painting and attaching accessories that are not manufactured by HJC for this helmet.
If you have any questions about modifications, please email us at [email protected].
An improperly stored helmet can become damaged and may increase your risk of serious injury or death in an accident. You should:
Store helmet in a cool and dry place,
Keep helmet away from pets and other animals,
Keep helmet away from the heat in excess of 50ºC and do not set on or near hot surfaces.
