This not only benefits the handling; it also provides a flow-optimized inflow angle at the intake membrane – a prerequisite for maximum performance.

Clutch (Serial)

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.

Automatic transmission (Serial)

The centrifugally controlled, multi-disc automatic clutch developed by KTM delivers easily controllable acceleration and makes riding the 50 SX the easiest thing in the world.
