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?

Here is a very simple answer. The more torque *at the wheels* the faster you accelerate.
[Here is a graph of torque at the wheels on a CB500F](https://motostatz.com/wp-content/uploads/2021/07/CB500F-in-gear-acceleration-e1660277766742-1024×588.jpg)
Note how torque at the wheels in first gear is higher across the *entire rev range* than peak torque in second.
So if you for example accelerate through 3nd gear, then no, it won’t pull harder at higher revs, it’ll pull hardest at peak torque.
But you have gears, so you wouldn’t accelerate in 3rd, you’d drop to 2nd (and higher revs) and use a lower gear to turn that power into more torque at the wheels than anywhere in 3rd.
So no, you don’t accelerate harder with more revs, you accelerate harder in lower gears, and lower gears require more revs to do the same speed 😛
