In detail, there can be any number of small differences in stroke, bearing surfaces, diameters, end fittings ASO.
But there's no principal difference that will 100% separate a 2-stroke crank from a 4-stroke crank.
A 4-stroke is more likely to have an oil pump, and the bearings pressure-lubricated through holes and channels in the crank and a 2-stroke is more likely to get its lubrication through the oil-mixed fuel/air mix being circulated through the crankcase.
But you can have splash-lubed 4-strokes and pressure lubed 2-strokes.

What is the difference between Two and Four Stroke IC engine.Thermodynamically?
There is no thermodynamic difference between them .
How can YOU identify a two stroke or four stroke engine by seeing it?
if you see the difference between valves
How many degrees of crankshaft rotationare needed to complete the four stroke?
In a four-stroke engine, one complete cycle consists of four strokes: intake, compression, power, and exhaust. This cycle requires two complete revolutions of the crankshaft, which equals 720 degrees of crankshaft rotation. Therefore, 720 degrees of crankshaft rotation are needed to complete the four-stroke cycle.
What statement correctly describes a four-stroke engine?
The four-stroke engine produces 1 power stroke for every 720 degrees of crankshaft rotation.
How many degrees crankshaft rotation compose one stroke of four stroke engine?
180 degrees per stroke.
How often or how many degrees of rotation of the crankshaft will a power stroke be delivered in a four cylinder engine?
In a four-cylinder engine, a power stroke occurs once every two revolutions of the crankshaft. Since there are four cylinders, each cylinder completes a power stroke at intervals of 180 degrees of crankshaft rotation. Therefore, a power stroke is delivered every 90 degrees of crankshaft rotation when considering the firing order of the cylinders.
How many rotations of the crankshaft are required to complete each stroke of a?
In a four-stroke engine, the crankshaft completes two rotations to complete one full cycle of all four strokes: intake, compression, power, and exhaust. This means that each stroke of the engine corresponds to half a rotation of the crankshaft. Therefore, for each individual stroke, one full rotation of the crankshaft is required for two strokes.
How many degrees crankshaft rotation compose half stroke of four stroke engine?
90 degrees would be a half stroke.
What is difference between valve and port?
valves are use in four stroke engine, and ports are use in two stroke engine.
Does the four-stroke engine produces 1 power stroke for every 720 degrees of crankshaft rotation?
Yes, if by "720 degrees of crankshaft rotation" you mean "two rotations" Here is a great animation of a four-stroke at work: http://www.animatedengines.com/otto.shtml
What is the difference between a Kawasaki kx 125 and a Kawasaki klx 125?
the difference is that a kx is a 2 stroke bike and a klx is a four stroke. the difference in strokes is the cylinders and a 2 stroke needs gas mixed with the oil
What is the difference between a 2 stroke and a 4 stroke lawn mower engine?
Four-stroke engines have a spout where you add oil to the engine. On two-stroke engines, oil has to be added to the fuel. (Four-stroke and two-stroke are also called four-cycle and two-cycle, respectively).
