The stem differs depending from the model - an S-stem weights about 880g, an H-stem about 910g, P and M about 810g.
Mine are 1271gr (for main frame) and 461gr for S-stem. I have seen pictures of ti frame that weighs as little as 1100gr, and S-stem as little as 380gr (maybe special ordered ones).
So 1.2~1.5kg saving over stock steel ones.

Yes, that's a bit of exaggeration, but here the Ni edition is only available as S2L-X configuration. It weighs 10.24kg on scale.
My build will be 4.39kg lighter than that.
S2L-X Ni scaled

Here even ordinary titanium Bromptons are quite expensive (almost $2.8K). I guess the Bromptons are cheapest in UK, but titanium ones are still around $2K USD. So titanium clone is still cheaper.
And honestly all the stock Brompton parts are quite crappy and has negligible resale value anyway nowadays (at least here... many people just use the frameset and dump the rest)
