it will go 650 mphs
Depending on the type of 250cc engine, two-stroke or four-stroke, and the state of tune of the engine you can expect anywhere between 20hp for a nice relaxed trail bike to over 40 hp from a fire breathing two-stroke motocrosser.
The horsepower of a 250cc engine can vary depending on the type of engine and its design. Generally, a 250cc engine produces around 20 to 30 horsepower, but this can differ based on factors like whether it's a two-stroke or four-stroke engine. For example, a high-performance two-stroke engine might achieve higher horsepower compared to a standard four-stroke engine.
150mph in full road race trim... assuming four cylinders and two-stroke. The Ninja 250 R, one of the fastest production sport bikes goes 95 mph without any modifications. It has 2 carbs and 2 cylinders.
two stroke engines have a power stroke every second revolution of the crank shaft. four strokes have a power stroke every fourth revolution of the crank shaft. that is why a 125cc two stroke has about the same power as a 250cc four stroke.
Depends what kind it is, what brand, if it is four or two stroke. depends on a lot of things but you must look at many different sites to see how fast
yes
Two strokes can accelerate faster but it depends on engine size

A 125cc four-stroke dirt bike typically reaches speeds of around 50 to 60 mph (80 to 97 km/h), depending on factors such as the rider's weight, terrain, and bike modifications. Four-stroke engines tend to provide more torque and smoother power delivery compared to two-stroke engines, which can affect acceleration and overall performance. However, the actual top speed can vary by model and manufacturer.
