125 motorcycle oil filter is located under a round cover on the right side of the engine. The oil filter is a cylindrical component that requires regular replacement. It should be changed every time the engine oil is replaced, as its function is to filter the engine oil. The term "125 motorcycle" specifically refers to motorcycles with an engine displacement of around 125CC. Major motorcycle manufacturers have developed various engine models and brand motorcycles based on this displacement. Motorcycles are two- or three-wheeled vehicles powered by gasoline engines and steered by handlebars to control the front wheel. They are lightweight, agile, and fast, widely used for patrol, passenger and cargo transportation, and also serve as sports equipment. Motorcycles can be categorized into street bikes, road racing motorcycles, off-road motorcycles, cruisers, and tourers.

On my 125cc motorcycle, the oil filter is typically located in the lower area of the engine, adjacent to the oil pan as a cylindrical component. After riding for several years, I've noticed this position is designed for easy replacement—simply remove the bottom protective cover to access the screw-fastened part. Some models position the filter on the side or toward the front, requiring a specialized wrench for gentle removal during disassembly. Remember to drain the old oil before replacement, and after installing the new filter, refill with fresh oil while checking for leaks. If the filter area isn't cleaned regularly, sludge buildup can reduce filtration efficiency. Routine maintenance checks help prevent sudden clogs and extend engine life. Especially before long trips, ensuring the filter area is clean is a wise precaution.

Having used several 125cc motorcycles, I found that most oil filters are located near the oil pan beneath the engine. The position is designed for maintenance convenience, though it might be tricky to locate at first. For instance, on my Suzuki model, the filter was under a metal cover and easily accessible with a small wrench. Knowing its location saves time and helps diagnose oil pressure issues—like overheating caused by a dirty filter. Regular filter replacement is crucial, and improper positioning can lead to oil leaks, so always use a new sealing ring to ensure tightness. Riders often share tips, such as replacing the filter after the engine cools to avoid burn risks. The filter's role is to trap debris, and an easily reachable location simplifies upkeep, reducing repair costs.

When repairing various 125cc motorcycles, the filter is usually located at the bottom of the engine, secured by screws in a metal cylindrical housing. The position is chosen to simplify maintenance, allowing replacement and cleaning with basic tools. Some models place the filter at the side or rear, clearly visible after removing the cover. Remembering its location facilitates routine checks, preventing oil flow issues that cause wear. Replacement steps include noting the tightening direction when unscrewing to avoid damaging threads and compromising the seal. A clogged filter often leads to increased fuel consumption and engine noise, so timely attention to its position ensures safe riding.
