the outputs are deactivated individually , with the error status of each unit indicated by a red or green LED light . This makes for quick and easy troubleshooting on the trail .
2T ENGINES In terms of engines , the two-strokes are debuting new electronic Throttle Body Injection technology . Dubbed TBI for short , it ’ s said to provide almost carburettor levels of ultrasmooth power delivery , while eliminating the need for re-jetting at different altitudes . The reed valve case has also received an important design update , with new plastic flaps on the outside of the reed valve case for improved sealing of the intake tract . This new design avoids fuel excess in extreme upor downhill sections which could lead to the fuelling running rich . According to KTM , a beneficial side effect of the new electronic fuel injection and the ECU is implementing the new electronic exhaust control , allowing for two different engine maps , selectable via an optional Map Select switch .
4T ENGINES The four-stroke model range provides the most
concise offering of models . All models in the four-stroke range benefit from class-winning engines , engineered to deliver massive torque down low with an explosive power delivery at higher RPMs . An improved centre of gravity was achieved by tilting the engine 2 ° backward and repositioning the front sprocket 3mm lower , for improved handling and manoeuvrability . Together with the benefits of mass centralisation and reduced weight , the antisquat behaviour of the chassis was improved making for better traction on extreme inclines and powering out of corners in special enduro stages .
QUICKSHIFTER The 2024 KTM EXC-F also debuts the optional addition of Traction Control and for the first time ever on an enduro machine – a Quickshifter function . The latter makes for clutchless upshifts from 2nd to 6th gear , allowing riders to keep the throttle pinned while changing through the gears for improved control . These can be toggled on or off via an optional and newly designed Map Select Switch .
