Adjustablity
Different adjustability options were built into the KTM 50 SX using scientific statistical data and feedback from young racers. Finding the perfect fit for your little ripper is easy thanks to height-adjustable suspension, adjustable handlebar positioning, subframe, and bodywork. This allows the seat height to be adjusted from a low setting of 634 mm up to 682 mm, while the KTM 50 SX comes standard from the factory with a seat height of 653 mm.
Ignition
A digital ignition with improved processing power makes for a cleaner burn and smoother power delivery. Individual ignition timing across the entire rpm range, just like that found on the full-sized KTM SX range, adds a key advantage. The throttle cable assembly benefits from a new stabilization cap that extends the lifetime of the cable by reducing the risk of kinking and damage.
Carburetor
A proven Dell'Orto type PHBG 19 BS carburetor takes a prime position in producing the goods in the KTM 50 SX, working perfectly in harmony with the engine, exhaust, and air intake design.
