i am 200lbs
wife is 95 soaking wet w rocks in her shoes.
i use the stock seat for fun romps through the side roads. i will replace that rock soon.
i use the rallyrunner w short sis bar, and rack for 2 up rides to the beach, and around town areas. she doesn't complain about the seat, but she has been on the back for 20+ years... you complain, you stay home.
the Heritage '91 sits idle in the garage with problems.
