The compression ratio is the ratio of the volume of the cylinder and the combustion chamber when the piston is at the bottom, and the volume of the combustion chamber when the piston is at the top. Automotive engineers can improve fuel efficiency and fuel economy by designing engines with high compression ratios.
And because this motor runs cooler, Harley-Davidson has been able to increase its compression ratio from 9.6:1 to 10.1:1. Along with this increase and a change in the air box design, the High Output 103 offers, according to Harley-Davidson, around 10.7 percnt more peak torque than the standard 103 engine.
