Front Wheel size

[The Pig]

I would like to understand the reason why my 1200 Adv has a 19inch rather than a 21inch front  wheel?
My understanding is that the 19 inch is better for roadholding and cornering, and the 21inch is better offroad...is this correct? Can any wild dog  give me an opinion on his experience comparing both wheels  ..thanks
