What is the displacement of a 500cc motorcycle?

[LeDiana]

If we use the mainstream 'L' as the displacement unit in the automotive field, a 500cc motorcycle has a displacement of 0.5L. Here, '500CC' refers to the exhaust volume of the motorcycle engine's combustion chamber, where CC is the volume unit for cylinder displacement, with 1CC being equivalent to 1ml. According to relevant standards in our country, different displacements correspond to the following vehicle types: 30CC and below are defined as fuel-powered mopeds. 30-50CC are defined as light motorcycles. Above 50CC is defined as a standard motorcycle. Among standard motorcycles, they can be further categorized as follows: entry-level motorcycles are defined as 250-400CC. Mid-level motorcycles are defined as 500-750CC. Heavy motorcycles (liter-class) are defined as above 1000CC. Motorcycle licenses are divided into categories D, E, and F. Motorcycles come in two types: two-wheeled and three-wheeled. In addition to directly applying for a beginner's two-wheeled or three-wheeled motorcycle license, one can also apply for an upgrade to a two-wheeled or three-wheeled motorcycle license. Applicants can use their resident ID card to apply for a motorcycle driver's license anywhere nationwide, take the exam, and upon passing, receive their motorcycle driver's license. For daily maintenance of a motorcycle's engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil based on mechanical load, with the selection standard being no lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through, the filter may burst or the safety valve may open, allowing oil to bypass the filter and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.
