The Motorcycle is a ground based unit that is owned as a vehicle by Team America. It is used by Lisa and transported onto location via the Osprey.

The motorcycle is only seen once throughout the film during the chase in Cairo between Chris and Joe, and Gary and the terrorists. Lisa realizes that Gary is in the fleeing Jeep and races across the dessert to save him. She manages to do so just in time and pulls him up onto the back of the motorcycle. The motorcycle would presumably have continued being used by the team after the defeat of Kim Jong-il.
