Know your Full Face Motorcycle Helmet's anatomy
Just like your head, a helmet has plenty of parts that need to work together to protect your brain. These are the things to look for.
1. PROTECTIVE VISOR Shields face/eyes from sun/wind. Provides a mild level of crash protection. Also, helps reduce noise.
2. HARD OUTER SHELL Plastic, Kevlar, fiberglass or carbon fiber can all do a good job. The shell helps prevent penetration and presents a smooth, non-snag surface.
3. IMPACT-ABSORBING LINER The one part of your helmet you typically don’t see. Sandwiched between the tough outer shell and the soft inner liner, the expanded polystyrene/polypropylene (EPS) foam deforms and absorbs the energy of a blow. Never reuse a helmet that’s suffered a major blow: the liner is one-time-use only.
4. COMFORT LINER Some helmets feature removable liners you can launder; others let you add or remove padding to fine-tune fit.
5. AIRFLOW VENTS The best designs feature vents in the chin bar, over the brow, and exhaust vents in the back. All of these should open and close.
6. CHIN BAR A chin bar with an inner liner not only stiffens overall helmet construction, it protects this vulnerable area.
7. RETENTION SYSTEM Usually a tough nylon strap and a pair of “D” rings. Use it every time.
