The top speed of a 140cc engine can vary depending on different factors such as the type of vehicle it is installed in, gearing, and aerodynamics. On average, a 140cc engine can reach speeds of around 50-60 mph.

The size of an engine's piston capacity is not directly related to the vehicle's top speed.

How do you measure the speed in NASCAR?

They measure engine speed in RPM, but car speed in MPH. If you want to know how they know how fast the cars go from the stands or the officials' booths, that is what radar guns are for. Inside the cars, the speedometer tells how fast they are going, and the tachometer tells how fast the engine is running.
