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?

Ever bicycle uphill in a higher gear where you have to basically stand on the pedal to get it to move? Versus in a lower gear where you can pedal normally and putter uphill at a steady pace. Standing on the pedal is high torque low power, while pedaling at a steady pace is low-medium torque and higher power.
And when you pedal super duper fast, most of your energy is making the pedals spin and not really making the bicycle go faster, well it turns out your torque is dropping off to near zero at that point.
But just before that point, in-between getting the bicycle to start moving versus being maxed out, that’s your powerband, you can still put some weight on the pedals to push you ahead, but you are moving the pedals fast enough where each rotation gets you some more speed.
Mathematically, Power = torque x RPM. So given constant torque, you have more power at higher rpms.
You can’t feel torque from an engine, you can only feel power. And power is what makes an object accelerate. So max power is where you pull harder at high revs.
However in all engines, torque eventually drops off, the pistons can’t effectively rotate faster, and the power will decrease. So you shift gears!
