Bore is the size of the pistons. Stroke is each time the piston moves e.g. the piston moving up is 1 stroke then down is another stroke. there are both 2 and 4 stroke engines, a 2 stroke engine 'fires' once every revolution and a 4 stroke engine 'fires' every 2 revolutions. Hope that explains it!
The answer is not fully correct. Bore is indeed the size, meaning the "diameter" of the pistons, and the strokeis actually the "depth" of the piston from top to bottom. In other words, it is the distance that the pistons undergo in one stroke ( as explained above ). for example, in service manuals you will find : Bore and Stroke - 74 X 58 mm that is : Bore = 74mm & Stroke = 58mm . :) Ophir BYv :)

What does it mean by define an engine by its Bore X stroke?
bore is the diameter of the piston and stroke is the length the piston moves in the cylinder.for example if bore x stroke is 1x3 then 1 is the diameter of the piston and 3 is the length of the cylinder.if bore is greater than stroke then it is a short stroke engine.
What does bore x stroke mean?
Bore = the (internal) diameter of the cylnder hole in the engine block. Stroke = the distance the piston travels up (or down) the bore during its' cycle. If you multiply the bore dimension by the stroke dimension you will get the volumetric displacement of that cylinder. thus, Vd = (3.1416/4) (dia.) squared x Stroke
