Mini Racer is a type of racing vehicle that is smaller than a traditional race car. It is often used in kart racing, which is a form of motorsport that involves small, open-wheel vehicles. The term 'Mini Racer' is often used to refer to the karts used in this type of racing. Kart racing is popular among both professional and amateur racers, and is often seen as a stepping stone for those looking to move up to larger, more powerful race cars.
