If you look at both bikes they sure look the same.
As MZ never had the biggest lineup of bike models i would guess they are the same frame, motor even down to that hard ass seat ! Boy seats were not an MZ specialty.They should have outsourced the seats also.
You could call these guys and they would know.
http://www.bikeworx.com/ Look at all the other models the same baghira/mastif ,Scorpion what flavor you want ? plastic or no plastic.I would bet except small things like black motor different plastic you are looking at the same bike,just look at the way it sits.They both sit the same,but just call bikework and find out for sure.Just change out the wheels and you have your bike back good luck.
You're just left with yourself all the time, whatever you do anyway. You've got to get down to your own God in your own temple. It's all down to you, mate.
