Actually, getting a Banshee through a doorway is easier than you think.
Remove rear fenders, front fenders if uncut, 1 silencer, wheels, 1 front shock, unscrew 1 tierod completely, disconnect upper A arm from frame on side you pulled shock from and swing A arm rearward and swing suspension upward as far as it will go. Then it's just a matter of putting 1 front side through the doorway,move it over and then the other side, then 1 rear side through, move it over and then the other side rear. The 1 silencer has to come off so you can get the bike over far enough to get the 1st axle side through.
I've done it.
