I'm making this topic so that I can post the data I find, if anyone else wants to add to this topic, please feel free to do so. I know the tiger is the bigger animal on average, but I believe the difference is not out of the lions league. I'm not here to bash tigers, so don't think I am, I'd like a nice topic with facts please.
Both sexes too
200-220kg estimated lion.
Asiatic lioness's weighed around 130 kg.

200 - 235kg. lion
Recenly I read report of Amboseli Lion project. They had two females of about 109 and 112 kg, and two young males of ~150 and 160 kg.
We aren’t able to weigh all the lions we capture but we do have Lentim’s & Ndelie’s weights recorded as 180kg and 200kg respectively. We also have weights of three adult females recorded ranging from 130 to 150kgs. These weights are a bit larger than the weights recorded from the Amboseli lions though quite a bit smaller than the few weights we have recorded from our northern Laikipia lion project. In Laikipia, we have two female lions on record weighing in at 148kg & 180kg! So there may be some truth to the lions in southern Kenya Amboseli area being smaller than in other areas of Kenya. Unfortunately, we don’t have enough data to be certain.
Two male amur tigers, 180 kg, 179 kg. female 127kg.
