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

Horsepower is the work being done. Torque is basically how much work you can do at any given time. If the torque curve is flat, the horsepower curve will usually be a constant incline with rpm. So basically, as revs increase, it becomes easier and easier to do the same amount of work.
