There is no correlation between hp and cc, for instance, a 125cc motocross bike delivers around 25 hp, a 480cc briggs I/C flathead delivers 12 hp. The 140cc flathead lawn mower engines are between three and four hp.
You cannot determine horsepower from cubic centimeters no cubic inches. For example, a 125 cc 2 cycle motocross racing motorcycle produces upwards of 25 HP yet a 140 cc lawn mower engine produces about 3 HP. There is no correlation between the cc's and horsepower whatsoever.
