Yep, the SSSA monsters use the same 4 pin wheel from the superbike hub.
Yea, those 3 spokes are boat anchors, the 5 spokes aren't much better unfortunately. I ran 3 spoke magnesium's and they were MUCH lighter then the 5 spoke cast wheels from the later gen superbikes/monsters. If you want a light wheel, ya gotta go with forged and thats hard to find for cheap money.
