I think those pair of hand rails on the tank are for when you just sent your seat out to be restored;those rails are for having an 'abrasive,jerk' of a person lay down on the frame and 'act as the seat'..
You sit on top of the person's back to help cushion some of the bumps in the road:you wouldn't want to ride on just frame rails with no seat,right? That GW seat looks like it needs(too much foam,imo)some work done to it.
Those hand rails are for the human 'seat' to hang-on to while underway,while the foam seat is in the shop. A section in the rear of the faux fuel tank cover can be removed where the fuel fill cap is,so that the person's head can fit which will allow the human/'seat' to keep an eye on the electrics while underway
I admit,it's better to have a Real foam motorcycle stock seat;I imagine a person as a 'seat' would get real uncomfortable
This post might match some of the abominations we've seen on this thread;it could be the 'abominable ones' are the individuals who created some of these machines.. The machines can be fixed,but the ones who built these things?
I'm not too sure about that.
