Big Bad Toy Store or something so that you get a decent figure.
The Biker Scout is nicely articulated so that he can chase Ewoks all over Endor. He features: ball jointed ankles, ball jointed knees, ball jointed hips, a ball jointed torso, ball jointed shoulders, ball jointed elbows, swivel forearms, and a double ball jointed head. Lots of solid, movable joints here to give you a wide range of poses. I particularly like the double jointed head that allows for some great poses with the trooper looking up, down, and forward while riding a Speeder Bike.
