Dunno the Mahle weights, but the KB's are 575 grams with a 132 gr pin (vs 719 & 154? gr stock). Put in some SCAT rods and you have dropped the rod+pin+piston weight to around 1309 gr, versus the 1630 range for the same stock parts. The KB's come in the widest range of oversizes that I have seen so far.

Ross has some flat tops at 514 grams, and domes at 560 grams with similar pin weight as KB. Not sure if the Ross's are forged or hypers.

SRP has some hypers at 530 grams.
