Actually, from what I've seen in practical with engines from different displacement ranges, bigger cylinders in a smaller # usually lead to lower revving bands, altough a broader torque curve is easier to sustain, while smaller cylinders in a bigger amount usually lead to higher revving and more power, altough any eventual increasement in torque doesn't have the same proportion as the power increasements, plus getting more concentrated in higher RPMs. |
That does make sense to me esp in motorcycle terms. My 250 Ninja (parallel twin) was really high revving, but my old 03 1700 Warrior (v-twin) was very low revving. I don't think I ever took it over 3500 rpm
