How many kilometers for the first maintenance of a motorcycle?
1 Answers
Most motorcycles require their first maintenance after traveling 300 to 500 kilometers. The first maintenance is the initial service. The first maintenance only requires changing the engine oil and oil filter. Engine oil is referred to as the blood of the engine. Without engine oil, the engine cannot operate normally. Inside the engine, oil not only lubricates but also cleans, cools, prevents rust, and seals. When the engine is running, the oil forms a thin film on the surfaces of various components, preventing direct contact and friction between them. If engine components directly contact and rub against each other, it can accelerate engine wear and generate excessive heat, which is detrimental to the engine. Over time, the performance of engine oil degrades, so it needs to be replaced regularly. Failing to change the oil for extended periods can also accelerate engine wear. Conditions for changing engine oil: When the viscosity of the oil changes significantly under high temperatures—generally, if the 100°C kinematic viscosity deviates by more than 20%, it must be replaced. The oil's cleaning and dispersing properties deteriorate, making it unable to dissolve and disperse carbon deposits produced during engine operation. The oil becomes acidic, containing a large amount of acidic oxides that can corrode engine parts. The presence of metal particles in the oil accelerates wear on moving parts (the filtering effect of the mesh structure is not thorough enough). The flash point of the oil decreases, affecting safety. This is because frequent cold starts may allow gasoline to seep into the crankcase through the piston ring gaps. National standards stipulate that the flash point of gasoline engine oil must not be lower than 210°C.
