I just read the new HM848 has a polymer frame element like the MTS1200
MTS1200 "The frame features a trellis design up front with large-diameter thin-wall tubing, two central cast plates and two rear side elements made from welded tubing, closed by a rear load-bearing component made from fibreglass reinforced engineering plastics. "
HM848 "The frame connects into the seat rail and, as in the new Multistrada 1200, includes an intermediate section in engineering polymer. "
No shocker. Looks like the HM848 is borrowing a good bit from the MTS1200 - including the hippoMantis snout from the photos in your other post.
