For a new rider or an experienced rider who is replacing the old helmet, choosing a helmet may be more confusing than buying a bike. Finding the right helmet may be time-consuming, but it can be a rewarding experience. Studies have shown and riders have reported that helmets not only save lives but can drastically reduce the amount of injuries suffered to the face, head and neck. Some people claim that helmets restrict your vision, it's not true. Manufacturers design helmets to not obscure or block peripheral (side to side) vision. Others claim it reduces your hearing, it actually helps you hear over the engine.
Depending on the helmet manufacturer, it is recommended to replacing your helmet every 2-4 years. If your helmet is damaged or showing extreme wear it should be replaced. Replacing your helmet every few years is a good idea as its protection may deteriorate with time and wear. Also as newer materials and helmet designs become available, helmets become stronger, lighter, and more comfortable.
