How it's calculated
displacement (cc) = π/4 × bore² × stroke × cylinders / 1000 (bore, stroke in mm)
Common questions
Why divide by 1000?
Bore² × stroke gives cubic millimeters. Dividing by 1000 converts mm³ to cm³ (cc), which is the standard displacement unit.
Does displacement equal power?
No. Displacement sets the ceiling for airflow, but boosting, compression ratio, RPM, and tuning all shape actual power output.
