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.
