01. Engine & Exhaust

Engine

This little ripper of an engine features a high-performance cylinder, exhaust pipe and reed intake system, which are perfectly arranged for maximum performance, setting the standard in the highly competitive 50 cc class.

Cylinder

Engineered to withstand anything a budding young racer can throw at it, this high performance cylinder provides the goods in the highly contested and highly competitive 50 cc class.

Clutch

The KTM 50 SX MINI features a centrifugal multi-disc automatic clutch, which provides manageable acceleration for any young beginner. By simply twisting the throttle, young riders can experience the full READY TO RACE world of KTM. Plus, it can be adjusted to the specific requirements of the track and the rider in minutes and without any special tools.

Automatic transmission

The centrifugally controlled, multi-disc automatic clutch developed by KTM delivers easily controllable acceleration and makes riding the KTM 50 SX MINI as easy as twisting the throttle. Furthermore, it can still be quickly and easily adjusted to the specific requirements of both track and rider using the "KTM clicker system" - in a matter of seconds and with no special tools required.

Power reduction kit

For those future stars who are still absolute beginners, the engine power can be reduced using a kit from the PowerParts program. Afterall, we all had to start somewhere.

Cooling

Like the full-size KTM SX range, the KTM 50 SX MINI has a liquid cooling system, which even cools the crankcase. This is supported by large radiators providing outstanding heat dissipation, for remarkable reliability. 

Exhaust

The exhaust system was designed to perfectly match the characteristics of the engine, ensuring maximum output and a smooth power delivery over the entire rev range.

02. Chassis

Frame

This modern frame is made from lightweight, high strength chromoly steel profiles and combines maximum longitudinal stiffness with optimum torsional rigidity. It guarantees easy handling and precise cornering, but also outstanding stability at speed.

Wheels

Like the full-size KTM Factory racers, the 2023 KTM 50 SX MINI is fitted with lightweight, black anodized, aluminum rims which provide the highest strength and durability for any eventuality. These are wrapped in new MAXXIS MX-ST tires, to provide unmatched traction on any surface.

Fuel tank

Don't let its meager 2.1 liter fuel capacity fool you - the 2023 KTM 50 SX MINI is no slouch when it comes to going full race distance.
