[Title] Bore x Stroke [Description] 
In an engine, the relation between the diameter of the cylinder bore and the length of the stroke of the piston. This measurement tells you if the engine is designed to deliver more speed or more torque. A long-stroke engine (where the length of the piston stroke is greater than the diameter of the bore of a cylinder) delivers more torque at the expense of maximum power; while a short-stroke engine delivers more engine power with less low-end torque.
