01. Engine & Exhaust

Engine

The high performance cylinder, exhaust pipe and reed intake system are perfectly arranged for maximum performance, setting the standard in the highly competitive 50 cc class.

Clutch

Developed by KTM, the centrifugal multi-disc automatic clutch provides manageable acceleration and makes riding this motorcycle the easiest thing in the world. 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 the easiest thing in the world. 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 absolute beginners the engine power can be reduced to a moderate 5.5hp using a kit from the PowerParts program.

Cooling

Like the full-size KTM range, the KTM 50 SX MINI has a liquid cooling system, which even cools the crankcase. Generously sized radiators ensure outstanding heat dissipation, ensuring extra reliability, even under extremely heavy conditions.

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.
