although a generalization of engine design, but nonetheless true:

with equal displacement shorter stroke engines will wind up quicker & longer stroked engines will have more torque. This concept was 1st demonstrated to me when I began a career as a motorcycle mechanic in 1969. The long stoke Triumph 650's had more usable torque than the big bore BSA 650's. In that era, on the half mile & mile dirt tracks the Triumphs ruled.
