NEW FOR 2024

• Major refresh and update for the EXC and EXC-F range

Frame

• Frame has undergone major updates to improve overall dynamics, anti-squat behavior, and overall stability.
• Thicker frame walls now contribute to improved reliability.
• Specifically engineered longitudinal rigidity provides exceptional rider feedback, energy absorption, and stability. 
• Repositioning of rotating masses in the frame and forged steering head connection.  
• Topology-optimized frame wall thickness for specific rigidity and improved reliability in high-stress areas. 
• New shock mount, significantly improving anti-squat behavior. 
• New parallel frame mounts for improved flex characteristics on 2-stroke models. 
• Footrest mounts are moved inwards for less risk of hooking in deep ruts or when scrubbing. 
• Durable black finish with standard frame protectors, featuring a new KTM-specific texture. 
• Forged one-piece side stand gives the KTM Enduro range the ultimate parking stability.

Subframe

• Weighing in at only 1.815 kg, the new 2-piece polyamide-reinforced aluminum subframe provides impressive weight savings.
• Computational dynamics, carefully calculated rigidity was engineered into the subframe, delivering outstanding handling and feedback.
• Lower subframe supports and frame mounts are cast aluminium.
• Upper subframe is made from an injection-molded polyamide for flex.
• Subframe now more likely to flex and "bend back in to shape" following damage.
• The Offroad Control Unit (OCU) is integrated in to the subframe, where it remains dry, as well as electronic components.

Swingarm

• A new hollow, die-cast aluminum swingarm is designed to offer optimal stiffness and reliability at the lowest possible weight.
• The topology has been optimized for rigidity, while an improved casting process reduces weight by approximately 190 g.
• A new 22 mm rear axle has also been fitted to match the new flex characteristics of the chassis. 
• A new chain guard and chain sliders have been added, resulting in improved durability.
• Chain guard has less chance of hooking on boots or external objects.
• Reduction indirt build-up around the swingarm and chain guard.
• Chain adjustment markings are now also visible from above.

Triple Clamps and Handlebars

• A “more forgiving” high-flex steering stem for more shock absorption and flex to the rider.
• The upper triple clamp now tightened to 20 Nm, and the lower triple clamp to 15 Nm, for more stiffness.
• New topology-optimized bar mounts that provide increased surface area grip.
• New, black, tapered NEKEN aluminum handlebars.
• The same proprietary KTM bend as found on the latest KTM SX models.
• A larger, newly designed KTM branded bar pad for better protection and likeminded design pattern.

WP Closed Cartridge Forks

• All-new 48 mm WP XACT Closed Cartridge fork with a new mid-valve piston concept.
• Optimises the oil flow within the cartridge for fast, consistent damping.
• Avoids any unwanted foaming of fork oil preventing unwanted change in the damping characteristics.
• A new hydro stop in the last 68 mm of the stroke.
• Keeps maximum compression in reserve when tackling extreme obstacles like drop-offs.
• Updated fork protection rings, against dirt intrusion.
• Fork length increased from 928 mm to 940 mm.
• Stroke increased from 292 mm to 300 mm.
• Suspension settings taken from KTM and WP R&D.

WP XPLOR PDS Rear Shock

• All-new design of the adjustable shock.
• Progressive Damping System remains a signature element for KTM.
• More compact, with an overall length decreased from 415 mm to 402.7 mm.
• Stroke decreased from 105 mm to 102.7 mm.
• 380 g weight reduction.
• New main piston, designed to optimize oil flow and more consistent damping.
• New bearing seals which now set the benchmark when it comes to maintenance and service intervals. 
• Now with adjustable hand clickers, adjust on the fly without tools.
• Compression adjusted on the top; rebound on the bottom.
• Preload can also be adjusted by opening the securing ring with an Allen wrench and adjusting accordingly.

Ergonomics

• Complete refresh of the rider triangle, in focus to knee angle when standing.
• Added contact surfaces on the bodywork.
• New flat seat profile with new orange grip cover.
• Recessed grip pocket under the seat.
• New front fender with mud fins, keeping it away from rider and radiators.

CTG (Colour, Trim, Graphics)

• If you didn't know what CTG stood for, neither did I (thank you Google).
• Inspired from the 1990's using purple which was the primary with KTM back then (nod to the past).
• Orange remains the dominant as its proven to be durable over time.

Fuel Tank

• New 9 litre tank for two-stroke (4 stroke gets 8.5 litres).
• A transparent, polythene (XPE) tank with threaded filler cap.

Airbox

• Redesigned for 2024.
• Precisely positioned inlet ducts aimed at preventing air deformation.
• Ensures maximum airflow and maximum filter protection.
• Still easily accessed on the left with no tools behind a cover.
• TwinAir filter and filter cage design with foolproof mounting.
• Attention given to sealing the airbox for when around river crossings with a splash protector.

LED Headlight

• A completely new LED headlight unit.
• Light output has been improved by 300%.
• Riding in the dark now completely different, a big advantage for competition and events.
• The headlight mask itself integrates a triple clamp protector which covers the lower triple clamp.
• Inside the headlight, the LED lighting unit receives a new quick-release system.
• Can repair the headlight due to damage, negating the need to replace the entire unit.

Battery

• A Lithium-Ion battery which is 1 kg lighter than a lead acid battery.
• Retrofitment of a kick start is no longer possible, on any EXC or EXC-F model.

OCU (Offroad Control Unit)

• The all-new and totally independent OCU replaces the use of electronic fuses and relays.
• OCU can be found under the seat.
• If there is a electrical component failure, outputs are deactivated individually.
• Error status' are shown by a green or red LED marker, easy to diagnose when away.
• No need to carry spare fuses anymore.

ROS (Roll Over Sensor)

• Taken from the motocross range.
• Shuts the engine off in the event of a severe crash.

Optional Map Switch

• Switch between two engine maps (for two-stroke).
• Map 1 = mellow and standard; Map 2 = aggressive and crispy throttle.
• Traction Control, Quickshifter are not available on two-stroke.

Two Stroke Injection Updates

• Since 2018, TPI has been featured.
• All-new electronically controlled Throttle Body Injection system.
• With Keihin, a 39 mm throttle body was developed to withstand the harsh and full throttle demands of competitive motocross.
• A specifically tuned ECU from Vitesco works in conjunction with the Keihin throttle body.
• Always deliver the correct air-fuel mixture by constantly analyzing water temperature, air temperature.
• Also measures ambient pressure, along with the pressure within the crankcase, rpm, and throttle position.
• Newly designed injectors also work to provide an optimal burn rate.
• A improved Sauter mean diameter (SMD), producing a finer spray of fuel for a cleaner ignition and less fuel wastage.

Reed Valve

• The reed valve case has received an important design update.
• Newly added plastic flaps on the outside of the reed valve case, better sealing.
• Negates over-fueling in extreme up- or downhill sections, no bogging, no running rich.

Electric Power Valve

• The power valve is controlled according to the throttle position and engine RPMs.
• The EMS auto-calibrates, there’s no more hassle with incorrect power valve adjustments.
• Result is linear outputs and the ability to have the two engine maps with optional map switch.

Exhaust

• A more compact exhaust header design meaning better ground clearance.
• The silencer also benefits from the compact treatment, crafted from lightweight aluminum finished off in a black coating.
