It provides some protection against head injuries.
A helmet and a mask are similar, except that a helmet covers all of the head where a mask only covers the front (i.e. the face, jaw and the forwrad part of the hair). A mask may also be purely for decoration, such as a party mask or as part of a costume, while a helmet is often intended to provide real protection if struck, such as a hockey goalkeeper's or a motorbike rider's.

A bicycle fork is the portion of a bicycle that holds the front wheel and allows the rider to steer and balance the bicycle.

Helmet is most essential part of motorcycle riding for the sake of rider's safety. Even its illegal in Texas for passenger to travel with none helmeted rider.
A helmet is a riding garment. It protects the rider in case of a fall or a crash.
Auto racing helmets cannot be used for street bicycling or motorcycling, at least in many jurisdictions where minimum visual field requirements exist for a street legal helmet.Although auto racing helmets are similar in construction to motorcycle helmets and provide the same level of protection, they have a number of essential differences besides possessing fire protection required in ultra-high-speed car crashes:Car racing helmets are designed more for repeated impacts in a single place since a securely held racing driver will not move. In contrast, during a motorcycle crash the rider will hit his or her head in many places.Car racing helmets are shaped a little differently from motorcycle helmets because most hits are to the top of the driver's head rather than the front or the sides as in a motorcycle helmet. The full-face protection on a race car helmet will not extend as low on the face as in a motorcycle helmet.Race car helmets have very narrow visual fields. This means that if used on a street bike the rider could quite possibly not see a vehicle coming in from the side.These three features mean an auto racing helmet is not going to provide optimum protection for a motorcycle or bicycle rider on a public street, and could even be dangerous because it is so hard to see out of.
Motorcycle chaps are used to provide protection to the legs of a rider. They protect against the cold and wind as well as general protection in the event of a fall or accident.
