Actually, “torque is the force it would take to stall the motor†is not a great description. The best I can think of is literal. Imagine instead of a motor your motorcycle is being pulled by a rope tied to the front end. The other end of the rope is wrapped around a drum. the rotation of the drum is pulling the motorcycle forward. Another rope is wrapped around the drum. A weight is tied to the other end of that rope. The falling of that weight is the force that is rotating the drum, resulting in the motorcycle being pulled forward. Torque is that weight times the radius of the drum. Torque is not the weight, as a larger drum requires a smaller weight to accelerate the motorcycle at the same rate.
