What Displacement Motorcycles Can Be Licensed?
1 Answers
Currently, the maximum displacement allowed for motorcycles in China is above 250cc. Theoretically, any domestically produced motorcycle with a certificate of conformity can be licensed. According to regulations, any motor vehicle weighing over 40KG or with a maximum speed exceeding 20KM/h is classified as a motor vehicle and must be licensed before it can be driven on the road. Introduction to Displacement: Displacement, a specialized term in hydraulic transmission, refers to the volume of fluid inhaled or expelled per stroke or cycle. The space volume through which the piston moves from the top dead center to the bottom dead center is called the cylinder displacement; if the engine has multiple cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is generally expressed in liters (L). The Importance of Engine Displacement: Engine displacement is one of the most important structural parameters, more representative of the engine's size than cylinder bore and number. Many engine indicators are closely related to displacement. Generally, a larger displacement means the engine releases more energy per unit time (converting the chemical energy of fuel into mechanical energy), which translates to better "power performance." This is similar to comparing a teenage boy to a healthy adult—the adult is naturally more efficient at physical labor. Therefore, off-road vehicles and sports cars usually have relatively larger displacements.
