Let's just say, for argument's sake, that these two bikes are going down

the road side by side, same speed, and that speed amounts to 500 rear

wheel rpm, whatever speed that works out to.

The first bike has 100 horsepower, right? Well, 100 horsepower at 500

rear wheel rpm is 1050.4 ft-lbs of torque at the wheel.

The second bike has 70 horsepower. 70 horsepower at 500 rear wheel rpm

is 735.3 ft-lbs of torque at the wheel.

If the bikes are the same weight, the 100 horsepower bike is going to

walk away from the 70 horsepower bike, because even though it has less

torque at the crank, it has more at the rear wheel, and torque at the

rear wheel is what accelerates the bike.

The bike making the most horsepower puts the most torque to the rear

wheel at any given speed, it's a mathematical fact. That's why we talk

in terms of horsepower when talking of performance.
