Does a bigger rear sprocket give more horsepower???

Well no, you wouldn't necessarily alter the drivetrain loss to an appreciable level, but it does makes sense that you gain or lose WHP (Wheel Horsepower) due to the difference in torque multiplication through the final drive ratio - at least that's what it appears to show I believe

Though thinking about it, I guess you are more just moving the power band around at the rear wheel? Bare with me whilst I run this through my head... and write it all down



Acceleration can be altered by adjusting the final drive ratio. This seems sensible enough to me.

As Acceleration is a function of power (force) there must be a difference in power to obtain a difference in acceleration.

Therefore changing the sprockets (which we know alters the acceleration) must alter the available power at the rear wheel
