BRAKES

The hydraulic disc brakes on the 65 SX have been developed by brake specialist FORMULA. Heavy-duty 4-piston brake callipers bite hard into the lightweight 198 or 160 mm Wave brake discs.
 

ENGINE

Superior performance doesn't come from just anywhere; it's delivered by a KTM engine with the latest 2-stroke technology and a 6-speed transmission. The pressure-controlled exhaust valve (PCEV) delivers plenty of torque from the bottom end up and easy-to-ride, very linear power development. An optimised ignition curve guarantees reliable combustion across the whole rev range. Constant temperature control and hence consistently high performance are ensured by an intelligent cooling circuit with integrated crankcase cooling and two radiators.
CLUTCH

The 65 SX engine is equipped with a hydraulic clutch actuation system from FORMULA, which guarantees smooth and very precise clutch control. Moreover, it also has the same feel (clutch and brake levers are interchangeable) and the same looks as the front brake.
 

RADIATOR

Constant temperature control and hence consistently high performance are ensured by an intelligent cooling circuit with integrated crankcase cooling and two radiators.
