If torque determines a motorcycles accelaration, why does it pull harder at higher revs (bike with flat torque curve)

Question

i started riding a CB500F, it has a flat torque curve, pretty much the same torque at 3k and 9k rpm, then why does the bike (in the same gear) accelate much faster at higher than lower revs?

Answer 1

Torque times RPMs equals horsepower.

If you have a flat torque curve, you also have a linear increase in horsepower over that curve.

If your bike has the same torque at 3000 rpm as it does at 9000rpm, that means you’re getting 3x the horsepower at 9000.
