No, you can't. Because the two engines are not of the same size. The 250 cc engine is bigger than the 125 cc engine, so things will not fit between them.
The Honda Rebel 250 CMX250C has a 234 cubic centimeter straight -twin engine in it. This is the same engine that the Honda Nighthawk has. This bike was created to appeal to a younger generation.
I have a cr 125 and it goes like 90kph a 250 easily goes over 110kph Depending on the pipe and stuff and engine quality. Over 100 kph definitely
