Frequently Asked Questions
Compression ratio is the ratio of the volume of the cylinder and combustion chamber when the piston is at bottom dead center to the volume when the piston is at top dead center.
Displacement is the total volume swept by all pistons. It is calculated as π/4 * bore^2 * stroke * number of cylinders.
Bore and stroke are in millimeters, chamber volume in cubic centimeters (cc). The result displacement is in cc.
