The only thing that strokes the motor is a crank. Different rods and pistons
might change the angles between the rod and piston but does not change the
stroke or displacement. To change the displacement you have to change the
stroke or bore.

I think its from the longer distance the piston can travel during the
combustion phase.
The longer downstroke increases the amount of time that the expanding gas
has to turn the crank before reaching BDC per combustion cycle.
