He's got Minicon ports either side of the petrol tank - when mounted on the arm of a larger figure and turned wheels on he can look like a sort of dual buzzsaw weapon.
TF: Pull the seat in two along the middle and fold out to become the arms. Fold the flap on the petrol tank up to become the head. Pull the front of the bike down to become the legs and attempt to stand - what you're aiming for is to get him on the tips of the front mud guard and the base of the wind shield. He will stand in the end. Honest.
Poseability is essentially limited to the arms as the legs need to be in a very precise position to balance. He has hinged knees and ball jointed hips in addition to his ball jointed and hinged shoulders.
Not bad looking but he could balance better an awful lot better !
