How Many Horsepower Does a 125 Engine Have?

[IsabelaDella]

Domestic 4-stroke 125CC motorcycles typically have a power output of approximately 6～7kW, equivalent to 8～9.5 horsepower; 2-stroke 125 motorcycles can achieve up to 10kW, equivalent to 12.5 horsepower. Below are the detailed explanations: Horsepower Calculation: Multiply the engine's maximum power by 1.3629 to obtain the horsepower value. Displacement: The 125 refers to the engine displacement, which is the total working volume of all cylinders in the engine. It is calculated by multiplying the volume swept by the piston from top dead center to bottom dead center by the number of cylinders. Displacement is a crucial structural parameter that comprehensively measures the size of an engine. The performance indicators of an engine are closely related to its displacement. Generally, the larger the displacement of a vehicle, the higher its power output. Unit displacement is commonly used as a basis for evaluating the size of different engines.
