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.
Motorcycle Stability Control
Motorcycle Stability Control (MSC) is a motorcycle electronic brake control system developed by Robert Bosch GmbH. It is a lean-sensitive variation of the traditional ABS system Anti-lock braking system. The MSC system uses accelerometers and/or gyroscopic sensors to evaluate how close to the limit of adhesion the motorcycle is cornering. It reduces the allowable braking tire slip ratio, reducing the braking force, thus preventing the tire skid, and keeping the motorcycle from falling into the turn, or low-siding.
