It's much the same way my k1200r is pushing out 180HP from a 1.2 liter normally aspirated engine. RPM + flow. Most supersport bikes have even more HP on tap from a smaller engine. The key, however, is torque, that's what you want to look at. For instance, though my k1200r may have 180HP, it wouldn't do a very good job pushing around your 4 door car because it has only about 100 ftlb of torque. Torque is the rotational force of the engine.
