For 2019, KTM has reevaluated its 350 SX-F engine and in turn delivered a small power house that weighs a mere 26.6kg. The ultra lightweight engine delivers a very versatile power delivery with a max rpm range of 13,400rpm and a 57hp power output – this thing is sure to put you on the competitive edge. They have equipped the newly developed DS clutch in the 350 also, which it’s compact and rivet-less construction contributes to the lightweight design of the engine that also offers unbeatable reliability. The clutch is extremely heat resistant with steel clutch plates to ensure a smooth disengagement whilst a diaphragm spring is fitted so very little force is required to operate it. Just like all the other KTM four-stroke models, the 350 SX-F is fitted with a forged bridged box type piston produced from CP, the 350 has an 88mm bore where the piston crown geometry has been perfectly adapted to the combustion chamber, and in addition to the high compression ratio of 14:1, this engine delivers an extremely lively performance. There is a state of the art Keihin engine management system equipped on the KTM, while the electronic fuel injection features a 44mm throttle body with a new innovative injector position which delivers immediate throttle response. There is a modified throttle cable mount that provides a smoother routing of the cables with easier access. The ECU has been remapped to comply with the new exhaust and cylinder head design – there are a range of different maps for specific power curves depending on what gear you select, this all runs from the gear position sensor. There is a nifty little plastic tray underneath the seat to house the ECU and other electrical components to keep them in their place, increasing reliability and preventing any damage.
