2009 KTM 50SX

Small, fascinating and unbelievably snappy – that’s how best to describe this miniature rocket. Not only does it look like the big SX machines, it also has virtually identical riding behaviour. Both the chassis and the engine have been completely newly developed, which makes the 50 SX a fantastic handling, unbeatable high-tech weapon.

Take off and bring home the first wins of your career!
