The KTM 50 SX Mini is the smallest motocross bike in KTM's range, built for children taking their first steps in the sport. It uses a liquid-cooled 49cc two-stroke single with an automatic clutch, so there is no clutch lever to learn.
Its power can be restricted with a kit while a young rider builds confidence. Rivals include the Husqvarna TC 50 Mini and GAS GAS MC 50.
