Answer me this Mr Peabody ( that means anyone smart enough to explain it to a dumb guy)
Why isn't torque or horsepower linear thru a rev range..for example see torque charts on several sport bikes below. Notice how the torque rises and falls, then rises again then falls as rpms increase until the torque graph looks like a mountain range. Why does the torque fall off between 3500 and 5000 rpms even though rpms or cycles per minute is increasing?

Now look at the horsepower and torque of the CB 1100 (couldn't find an example of just the torque graph). Notice how the torque line is pretty much a constant as rpms increase

If both are a byproduct of each other, so much so that there is a formula for it, why does it dip on one chart and not on the other chart?
