XR650R Steel subframe weight?

I was just wondering if anyone here has a steel subframe on their XRR for more carrying weight, and how much the steel subframe weighs in comparison to the factory one? Looking for people with aftermarket steel subframes, not stuff you made yourself.

OK, then I'll shut up.
Mine's aluminium and self-made, no, worse, made it at home so home-made even!
I don't do cookies though, but the odd tart I do.
Ahem...

The Ozstralian lads are working on one solution and curently testing it , if it passes the ozzy test ( the best test ) then we will get small number of them made , they are exact copy of the original subframe just made of steel , slightly heavyer but much stronger .
