Although wearing a helmet isn't required by law, it is a device that could help to save your life.
There are three different types of helmets and they protect what they cover. The half helmet only covers the top of the head. A three-quarter helmet protects from around the ears to the top of the head. And the last, the full face helmet protects just that, the entire head and face giving the most protection to the rider.
A frequent rider and owner of Motorcycle Accessories has a word of advice to anyone who wants to ride or already does, "When you buy a motorcycle make the best deal you can on the motorcycle. When you buy a helmet buy the best one you can afford."
