I am currently rating two motorcycles to decide which one to buy. The criteria which is most important to me is the power-to-weight ratio. Now, I want to calculate the power of the motorcycle by looking at its displacement. The engine displacement is the amount of air-fuel mix that an engine can burn at a time. Looking at google, I cannot find a concrete formula to convert the engine displacement (cubic centimeter) to power (horsepower).
Currently, I am looking at two models:
- Suzuki Raider J 115 Fi (fuel injection)
- Honda XRS 125 (Carburetor)
I know that the Honda model will provide more power but I want to look at the other model's fuel efficiency. I want to convert to see whether the power difference is not that significant. For the sake of comparison/formula, assume that you feed both with the same amount of fuel.
Can you please advise?
