Important Safety Information
The instructions in this manual are designed to help you select the right helmet, wear it properly, take care of it, and know when
to replace it. Failure to follow these instruction may increase your risk of serious injury or death in an accident.
In order to get the most protection possible from your helmet, you should always do the following:
• Wear your helmet when you ride;
• Handle your helmet carefully to avoid accidental damage; and
• Ride safely – do not take risks because you are wearing a helmet.
Although your HJC helmet is designed to reduce or prevent some injuries when worn, no helmet can protect you from all possible or
foreseeable impacts. For example, your helmet cannot protect you from spinal or neck injuries. In addition, there is no guarantee that your
helmet will PREVENT injuries to the area of your head that is covered. A low speed accident may even result in serious injury or death.
Selecting the Right Helmet
Never buy a used helmet or borrow someone else's helmet. Over time the protective foam in helmets will adjust
to the contours of a user's head. A used or borrowed helmet may not offer as much protection as a new helmet.
Wearing the wrong size helmet can increase your risk of serious injury or death in an accident. A helmet that is
too large for your head may be dislodged or knocked off in an accident. To select the right size helmet for your
head, follow these instruction :

Always make sure you can see well enough to safely operate your motorcycle.
6. Test the helmet fit by placing your hands on each side of the helmet. While holding your head as motionless
as possible, try rotating your helmet from left to right then up and down. If you can feel the helmet padding
sliding on your head, it is too big, try a size smaller. You should feel the helmet move the skin on your
head and face as you try to move the helmet.
* The C91 was designed to be used in the closed chin bar position, thus be sure all helmet "fitting" is done while chin bar is
in the closed and locked position.
7. Fasten the retention system (chin strap) as tight as possible under your jaw without causing pain. There must be no slack
in the strap, and the strap must be tight up against your jaw. See page 8.
8. Test the retention system (chin strap)
• Put your hands on the back of the helmet and try to push the helmet off by rotating it forward.
• Put your hands on the front of the helmet above your forehead (or on the chin guard) and try to push
the helmet off by rotating backward.
If helmet comes off or shifts over your eyes, try another size or another model or brand. You must be able
to see the edge in your upper field of vision.
Repeat steps 3 throught 8 until you find a helmet that fits your head snugly and securely.
