Yes it is cast AL. From first hand experience the fake sump makes changing the oil extra labor. They need to be removed each time to access the oil filter. One of the oil lines also needs to be removed. Sh*ty design for the people like myself who actually rides the thing. Not a big issue for the ones who have their MH900e sitting in a living room somewhere. What a waste.
I say... Don't hide it. Ride it! ~8000 miles on mine
