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.
Triumph Tina
The Tina's patented drivetrain had technical problems. The CVT drive belt would derail and seize the transmission and the rear wheel, not only disabling the scooter but also preventing it from being pushed. Also, the starting procedure for the Tina required moving a switch on the handlebar to "start" before kick starting the scooter. This activated a governor to keep the engine speed too low to activate the transmission. If the switch were to be left in "drive" while the scooter was being started, then the motorcycle would accelerate immediately. This happened to Turner, resulting in a crash into a curb and a broken ankle.
