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.


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 big KTM bikes, the 50 SX has a liquid cooling system, which even cools the crankcase. Generously sized radiators ensure outstanding heat dissipation for high reliability, even under extremely heavy duty.


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.
