Tic
Simple motor tics are typically sudden, brief, meaningless movements that usually involve only one group of muscles, such as eye blinking, head jerking, or shoulder shrugging. Motor tics can be of an endless variety and may include such movements as hand clapping, neck stretching, mouth movements, head, arm or leg jerks, and facial grimacing.
ATK motorcycles
The Intimidator is a monster dirt-bike powered by a Maico two-stroke engine. As of June 2008, only Maico itself has a machine comparable to this because the Intimidator is the same bike with different badging.
ATK also has a line of atvs that use a 900cc efi engine.
