01. Engine & Exhaust


Engine
The KTM 65 SX features cutting-edge 2-stroke technology and an easy-to-shift 6-speed transmission with a hydraulic clutch. Benefitting from a reworked ignition curve, the cylinder, with its pressure-controlled exhaust valve, continues to provide class-leading power and plenty of torque.



Cylinder
The high performance cylinder features a pressure-controlled exhaust valve (PCEV) and provides unrivaled performance within the highly competitive 65 cc class.



Clutch
An outstanding feature of the KTM 65 SX is the hydraulic clutch made by Formula. It provides easy clutch action and well-defined modulation.



Cooling
An intelligent cooling circuit with integrated crankcase cooling and two radiators improves the heat dissipation and ensures a constant temperature balance for consistent, high performance.
