Engine displacement (cc)
In Turkish: Motor hacmi (cc)
In short
Engine displacement is the total volume swept by the pistons from bottom to top dead centre, expressed in cubic centimetres (cc).
Calculation: displacement = π ÷ 4 × bore² × stroke × number of cylinders. For example, a single-cylinder engine with a 52.4 mm bore and 57.9 mm stroke displaces π ÷ 4 × 5.24² × 5.79 ≈ 124.9 cc.
- Displacement alone does not determine power; engine design, rpm and the torque curve also matter.
- Do not mix up different engines of the same capacity when matching parts; go by model and year.
- Licence categories and taxes are based on capacity and power.
