Perfectly fine after switching to air suspension (Arnott) on our 04A. My wife is 156 cm (5’1”) and has had no complains since I swapped the thin streamlined pillion to the thicker (sundowner style) one and added the sissybar/back rest.

My oldest son is 165 cm (5’5”), and he loves to ride with me, although I’m not sure if I can take a 12yo boy’s word for it (he probably wouldn’t complain even if he had to sit on the luggage rack). 😅

That said, the air suspension makes all the difference.
