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 as easy as twisting the throttle. It can be adjusted to the specific requirements of the track and the rider in minutes and without any special tools.


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.


Cooling
Like the full-size KTM range, the 50 SX 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.
