Ready to set the pace, the KTM 300 EXC HARDENDURO has rolled out of pitlane and onto the prologue startline. Based on the all-new KTM 300 EXC, the KTM 300 EXC HARDENDURO sets itself apart, bristling with an exclusive HARDENDURO package.

2024 KTM 500 EXC-F -WP XACT Shock


Getting READY TO RACE has never been easier. Thanks in part to its all-new suspension, the KTM 300 EXC HARDENDURO range boasts totally tool-free suspension setup at both ends. At the rear, our legendary, race-winning PDS technology features an all-new shock absorber design with hand-adjustable dual compression controls. This allows riders to adjust high- and low-speed settings in a matter of seconds. On the front, the forks are also easily adjusted thanks to hand-adjustable clickers on the bottom of the fork shoe and on the fork top cap, making changing settings on the fly as easy as twisting the throttle.

2024 KTM 500 EXC-F -Airbox


Maximum airflow with minimal water intrusion, a new air filter box is designed with precisely positioned inlet ducts aimed at preventing air deformation and maintaining filter protection. An enduro-specific splash protector under the airbox prevents water or dirt from splashing up from the rear wheel, while the Twin Air filter and air filter support design feature a simple fail-proof mounting system for safe and accurate filter installation, ensuring the air filter is easily accessed, without tools, for fast track-side maintenance.



The KTM 300 EXC HARDENDURO is designed to allow easy access to service parts with added service markers - like these ▲ - and draining nodes without the need for excessive tools and pit crews. The reason? Faster track-side and off-season maintenance to ensure you're ready to head for the hills at a moment's notice.

The transparent, polythene (XPE) fuel tank is a signature element of the KTM Enduro lineup. Not only does this let you keep an eye on your fuel level with a quick glance, but years of development mean it's the strongest, most reliable fuel tank yet. For 2024, a one-piece fuel pump and filter improve the fuel supply allowing the tank to be emptied further at a low fuel level. And with 9 liters of fuel at your disposal, you can hit the trail or track with utmost confidence.

Celebrating the toughest races on planet Earth, the KTM 300 EXC HARDENDURO features a loud, proud graphics kit. Featuring a gritty, textured tone and set off by brilliant orange bodywork, seat cover, and frame, it is instantly recognizable.



Let's start with the numbers; 49 hp, 43,8 Nm and 24.6 kg. This new 300cc 2-stroke powerplant not only brings a new choice into the E3 Enduro category, but remains the idea choice for Enduro riders wanting maximum power and torque at the least possible weight. Another reason why the KTM 300 EXC engine sets the benchmark in the competitive Enduro E3 class and in hard enduro races all over the world.



An all-new Offroad Control Unit - or OCU - under the seat replaces all the electronic fuses and relays. All outputs are switched depending on signals from the voltage regulator and the ECU continuously. In the event of over-current, outputs are deactivated individually. This makes for easy error detection as the status of each output is indicated by a red or green LED light. This means diagnosing an electrical issue out on the trail is as easy as lifting the seat, and there's no more need to carry fiddly fuses.

Designed for easy operation, the newly developed map select switch comes standard on the KTM 300 EXC HARDENDURO and allows for the easy selection of 2 unique engine maps. Map 1 is the standard, more linear, and predictable power map, while map 2 is a more aggressive map for added throttle response and more crisp, explosive power output.



Forget TPI, the 2024 KTM 2-stroke Enduro models feature all-new electronically-controlled Throttle Body Injection - or TBI. The ECU, together with a new Keihin 39mm throttle body, calculates the ideal air-fuel mixture by constantly analyzing water temperature, air temperature, ambient pressure, and pressure within the crankcase, the rpm, and the throttle position to ensure the smoothest and most consistent power delivery in the most gnarly of enduro conditions.



As with the rest of the 2024 2-stroke EXC range, the KTM 300 EXC HARDENDURO is fitted with a proven, reliable electric start system. Powered by an ultra lightweight 2 Ah lithium-ion starter battery, it provides a safe, reliable starting time and time again, while the wiring harness has most of the electrical components carefully positioned under the seat for easy accessibility.

For 2024, the reed valve case has received an important design update along with electronic exhaust control. New plastic flaps on the outer reed valve case provide improved sealing of the whole intake tract, preventing excess fueling in extreme up or downhill sections which could lead to rich engine settings.

Specifically engineered for longitudinal rigidity, the KTM 300 EXC HARDENDURO is engineered around an all-new gloss-orange powder-coated frame providing exceptional rider feedback, energy absorption, and high-speed stability. This has been achieved by repositioning the rotating masses in the frame and the inclusion of a forged steering head connection. The footrest mounts have also moved inwards, slimming things down for less risk of hooking up when tackling narrow single tracks, or charging through rock gardens. And when the ride comes to an end, a completely redesigned forged one-piece side stand ensures your enduro weapon stands proud. All-new orange and black factory frame protectors and a composite skid plate completes the package.

A new ultra-light lightweight subframe takes charge at the rear of the main frame, featuring a 2-part polyamide and reinforced aluminum construction. With the help of computational dynamics, a specific rigidity was engineered into the subframe, to deliver outstanding handling and rider feedback. The new subframe is also shorter, more compact, and more robust than the previous generation, with the ability to bend and flex in the event of a crash, rather than break. The subframe fully integrates the electronic components, without any extra need for brackets, holders, or unnecessary fixtures.

2024 KTM 500 EXC-F -WP XACT Closed-cartidge Fork

Providing fast and consistent damping, optimized oil flow, and a new hydro stop in the last 68 mm of the stroke, the forks ensure unmatched performance at any level. New fork protection rings also provide improved protection against dirt intrusion. Best of all, the new fork allows for full adjustment of compression and rebound without the need for any tools.

This remains the most reliable and maintenance-friendly option for competitive enduro racing. Moreover, an all-new WP XPLOR PDS rear shock now takes charge at the rear, weighing 380 g less than the previous generation unit. It features a new compact design, new bearings seals, and a new main piston for optimized oil flow, and improved, consistent damping, as well as providing full adjustability thanks to easy-to-use hand clickers for adjustments on the fly.

Besides the expertly crafted, hydro-formed, laser-cut, and robot-welded frame being engineered to provide exceptional rider feedback and straight-line stability, a number of components mean the frame acts as a "shock absorber" making for a less harsh ride, resulting in less rider fatigue over many hard laps. A new shock mounting, no longer connected to the main tube, significantly improves the anti-squat of the chassis. In contrast, a new, service-friendly one-piece steering head seal provides improved reliability. The closed-head tube design also provides a new routing for the fuel overflow. And lastly, a new forged one-piece side stand means no more sinking feelings when parking up.
