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.
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
KTM!!!
no
Two strokes can accelerate faster but it depends on engine size
CRF 150 R
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.
2 stroke
that engine code is not a four stroke, its 2 stroke 80cc
