How fast can a 125cc motorcycle go?

[DelCollin]

Domestic 125cc motorcycles can reach a maximum speed of 90-100 kilometers per hour. Below is relevant information: Motorcycle speed: Most motorcycles can reach 100 kilometers per hour, while more advanced models can achieve speeds of 180 kilometers per hour or even exceed 200 kilometers per hour. Single-cylinder 125cc motorcycle power: The typical power output for a single-cylinder 125cc motorcycle ranges from 7 to 8.3 kilowatts, while a 150cc single-cylinder engine generally produces between 8.8 and 11 kilowatts. Due to variations in engine technology among different motorcycle manufacturers, the power output of engines also differs. Engine power is influenced by factors such as displacement, vehicle weight, and engine technology (e.g., turbocharging), so motorcycles with the same 125cc displacement may not necessarily have identical power outputs. Since engine power is related to rotational speed, there are inevitably differences in the engine power curve (essentially the torque characteristic curve).
