Opinion is that they are sprung for riders weighing 72kg rider.
so if assuming a 50/50 Front/rear bias then 36kg on the front, roughly a 90kg rider would put another 9kg on the front and if the bike weighs 180kg wet it puts 90kg on the front so spring rates would need to be about 4% higher
and so on
