Engine size (cc)
Engine displacement in cubic centimetres. Bigger usually means more power, but design and tuning matter more.
cc (cubic centimetres) is the total volume of an engine's cylinders. In many countries licences and taxes depend on it (for example 125 cc or 400 cc limits). A modern 400 cc engine can make more power than an old 500 cc one.
Also called: cc, displacement, cubic capacity
