The importance of motorcycle helmets lies in the fact that for motorcycle drivers and passengers, the head is the most vulnerable part of the body when not wearing a helmet, accounting for approximately 64.8% of injuries. Head injuries mainly include skull base fractures and brain contusions. Almost all fatalities and disabilities involve head injuries, which are often fatal. Composition of Helmets: They are mostly semi-circular in shape and primarily consist of three parts: the outer shell, inner lining, and suspension system. The outer shell is made from materials such as special steel, fiberglass, reinforced plastic, leather, and nylon to protect against bullets, shrapnel, and other impacts to the head. Function of Helmets: Helmets are protective gear for the head, serving as essential headwear for military training and combat, as well as a crucial tool in transportation. They are categorized into military helmets, police helmets, and civilian helmets, among others.

Relevant information is introduced as follows: The thermal section of a two-stroke motorcycle mainly consists of components such as the cylinder head, cylinder, piston, and piston rings. In contrast, the thermal section of a four-stroke motorcycle includes the cylinder head, cylinder head cover, cylinder, piston, piston rings, and the valve train. The valve train comprises parts like valves, valve guides, valve seats, valve springs, camshafts, timing chains, timing sprockets, chain tensioners, and rocker arms.
