With the increase in displacement realized by increasing the stroke only, the fuel economy might not be much worse than the 250 depending on how aggressively they tuned the cams and intake runner. A few of the larger riders in the USA complained of top speeds of only 75 mph/ 120 kph into headwinds with the CBR250R so Honda may have selected a higher rpm state of tune to get more power per cc along with the extra displacement. But now that they make the excellent family of CBR500's, riders over 200 pounds/ 90kg would be better off to just choose one of those as their fuel consumption at highway speeds will be about the same due to the 500's square bore/ stroke even though they have almost twice the power available.
