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?

The real answer? It doesn’t. You’re probably feeling the peak of your torque curve (yes, even the flattest torque curves have a rise, peak, and fall) motorcycles tend to have their peak torque pretty high up.
But, let’s do some mental exercise. Let’s assume your engine makes a constant 50 torques. That torque is applied at every rotation the engine makes. So at 3,000 rpm (rotations per minute) you can apply that 50 torque 3,000 times within one minute. At 9,000 rpm you can apply that same 50 torque 9,000 times within one minute. The more times you can apply the torque within a time span, the faster you can move an object.
Of course, this is all simplified and hypothetical, and engines do not make constant torque, and there are hundreds of factors that affect their operation and power/torque output.
