A Mat Rempit is a Malaysian term for "An individual who participates in activities such as illegal street racing, bike stunt performance, petty crime and public disturbance using a motorcycle", usually involving 2- and 4-stroke underbone motorcycles,[1] colloquially known as Kapcai, or scooters. Mat Rempits are often seen on Malaysian streets, where they would gather in groups ranging from as small as 3 up to several dozen bikes at a predetermined place and go against each other for cheap thrills such as races and stunts, such as the wheelie, superman (lying flat on the seat), wikang, and scorpion (standing on the seat with one leg during a wheelie) and many flashier and dangerous ones. Generally, Mat Rempits tend to avoid the authorities and seem to be well-informed of their whereabouts. However, there are also cases where they openly rebel against authorities where they would run though roadblocks, ride against the traffic or hit police officers with their bikes. Mat Rempits often race of perform stunts without proper safety gear and properly-equipped bikes, which often lead to accidents, causing major injuries or death.
