Surely nobody really thinks altering gearing makes more horsepower!

Only adding stickers adds horsepower.

Correct Mickey, you would think it would remain unchanged, but to lose over 2 LB FT of torque on top is surprising with -1 +2 which is a common change.

The red ones have more HP.

No worries. My bike sleeps next to me in bed. Please don't judge me.
As to the original article... there isn't a horsepower change when changing sprockets, but you are changing the way that horsepower is applied. With a lower gear ratio you get to use more of that horsepower off the line, and a higher ratio gives you a higher top end speed. that is assuming that you have enough horsepower to handle the higher gear ratio.
I dreamed last night that someone stole my bike and the insurance company bought me a 2014 DLX. I liked the six speed! Woke up grinning and my wife hit me. Not sure what she thought I was dreaming of...
