162fmj is a 150 engine. Meaning of 162FMJ: It refers to a single-cylinder, 62mm bore air-cooled motorcycle engine. The '1' stands for single-cylinder, '62' represents the cylinder diameter, 'FM' indicates air-cooled, and 'J-V' is the manufacturer's internal code. Working process: A four-stroke engine means the piston completes four reciprocating movements for each ignition cycle in the cylinder. The four strokes are: Intake - the intake valve opens, the piston moves downward, and the mixture of gasoline and air is drawn into the cylinder; Compression - both intake and exhaust valves close, the piston moves upward, compressing the mixture; Combustion - when the mixture is compressed to its minimum, the spark plug ignites it, and the resulting pressure pushes the piston downward, rotating the crankshaft; Exhaust - when the piston reaches the bottom, the exhaust valve opens to release waste gas, and the piston continues moving upward to expel any remaining exhaust.

From my motorcycle riding experience, the 162FMJ is indeed commonly referred to as a 150 engine, as its displacement is approximately 162cc and it is classified in the market as a 150cc category. I have ridden several bikes equipped with this engine, such as some local brand commuter motorcycles. The power delivery is smooth, more than sufficient for daily commuting, and the acceleration is not too wild, making it suitable for beginners or medium to long-distance riding. The numbers '162' in the engine model directly represent the cc unit, while 'FMJ' is the manufacturer's code, but the overall structure and performance are no different from a standard 150. I recommend paying attention to maintenance records when buying a used bike. These engines are durable, and regular oil changes can extend their lifespan. If you encounter high fuel consumption issues, promptly check the air filter or spark plugs to ensure both driving safety and fuel economy.

I bought a used motorcycle, and the seller labeled it as 162FMJ. I specifically checked the information and confirmed that it belongs to the 150 engine category. The displacement is 162cc, numerically close to 160, but it is actually classified in the 150 group. The reason might be the manufacturer's standards or habits. It feels great to ride, with enough power and good fuel efficiency, making overtaking in the city effortless. As an average rider, I think this engine is suitable for daily commuting, especially when the weather is nice—it makes the ride super comfortable. Before buying, it's best to check the user manual or online forums to confirm the specifications and avoid being misled about having more power. Maintenance is simpler; just check the chain tension once a month.

Having ridden motorcycles for over a decade, the 162FMJ is undoubtedly a representative model of 150cc engines. With a displacement of 162cc, it belongs to the 150 family, offering reliable performance and affordable maintenance. This engine is commonly found in older models, featuring quick starts and low noise levels. However, be cautious about overloading and avoid prolonged high-speed riding, as it may lead to overheating issues.

From a technical perspective, the number '162' in the 162FMJ engine indicates a displacement of 162cc, but it is often categorized as a 150 engine because the 150cc class covers a range of 150-170cc. I have installed small components myself, and the model suffix 'FMJ' might be a manufacturer identifier, but its actual functionality is consistent with that of a 150. During use, pay attention to heat dissipation issues to avoid continuous riding in hot weather. Simply put, it has good compatibility and can adapt to various road conditions.
