The KTM 450 EXC-F SIX DAYS needs little introduction in enduro circles. Big power, unmatched agility, and truckloads of torque put this extreme READY TO RACE enduro weapon at the sharp end of any offroad battle. For 2025, it retains its championship-winning pedigree with a lightweight frame, closed-cartridge suspension, and a weapons chest of smart electronics to the paddock.
ADJUSTABILITY
Getting READY TO RACE has never been easier. The KTM EXC-F SIX DAYS range boasts a tool-free suspension setup at both ends. At the rear, our legendary, race-winning PDS technology features hand-adjustable dual compression controls, allowing 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.
AIR FILTER BOX
The air filter box is designed to ensure maximum airflow with minimal water intrusion. Precision in how the inlet ducts are positioned is 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 features a simple fail-proof mounting system for safe and accurate filter installation. All this ensures the air filter is easily accessed, without tools, for fast track-side maintenance.
FUEL TANK
The transparent, polythene (XPE) fuel tank is a signature element of the KTM Enduro lineup. Having undergone thorough race testing in everything from the GNCC to the hardest of FIM hard enduros, these tanks are built, well, like tanks! A one-piece fuel pump and filter manage fuel supply, while servicing is made extra simple with easy fuel filter access. What's more, an updated fuel tank roll now holds the tank more firmly in place and protects the frame against scrubbing.
SWITCHGEAR
On the right side of the handlebar, you'll find a new, sleeker start/stop switch, and on the left, a Mapping Select switch will allow riders to choose between Map 1 or Map 2, standard on all KTM EXC-F SIX DAYS models.
GRAPHICS
The 2025 KTM SIX DAYS range celebrates the latest installment of the ISDE in Spain with its most striking look to date. Boasting multiple shades of orange and sharp graphics, all that's left to say is, ¡Vamos!
ENGINE
The powerplant in the KTM 450 EXC-F SIX DAYS is a perfect example of advanced engineering techniques developed on the race track and transferred to the dealership floor. With an overall weight of just 29 kg, this powerplant is as powerful and it is prone to winning championships.
QUICKSHIFTER
Clutchless upshifts are the name of the game with the Quickshifter - fitted as standard on the 4-stroke KTM EXC-F SIX DAYS models. The function works by interrupting the ignition for a fraction of a second. This allows upshifting without the use of the clutch lever, while the throttle is fully opened. On the technical side, a sensor on the shift drum notices the force on the shift lever, sending the signal to the ECU and interrupting the ignition timing to slot the next gear in. The Quickshifter can also be deactivated via the new map select switch and is only active from 2nd to 6th gear.
TRACTION CONTROL
Blasting through wet and muddy terrain just got a lot easier with the Traction Control function- fitted as standard on the 4-stroke KTM EXC-F SIX DAYS models. TC analyzes throttle input from the rider and the rate at which the RPM increases in the engine. If the RPM increases too quickly, the EMS registers a loss of grip and reduces the amount of power to the rear wheel. This ensures maximum traction. Of course, it can be switched off for complete control.
OFFROAD CONTROL UNIT
The Offroad Control Unit - or OCU - is located under the seat and 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.
SELECTABLE ENGINE MAPS
Designed for easy operation, the map select switch comes standard on the KTM EXC SIX DAYS models 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.
BATTERY & WIRING HARNESS
As with the rest of the 2025 4-stroke KTM EXC-F range, the KTM 450 EXC-F SIX DAYS is fitted with a proven and 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.
ERGONOMICS
The KTM EXC range features a rider-focussed body-position triangle, providing improved knee contact - especially when standing on the pegs - with improved gripping surfaces all around. With the plastics working to expel mud buildup in wet, muddy conditions, a flat seat profile with a high grip seat cover providing exceptional rider movement and control, and a polyamide-reinforced aluminum subframe providing unmatched rider feel and feedback, your only concern is navigating the terrain ahead of you.
EXHAUST
Providing the bark to the 2025 KTM 450 EXC-F SIX DAYS bite, the exhaust system is designed to deliver hard-hitting performance at the lowest possible weight. The 2-piece header pipe design is made to be as compact as possible, with the routing of the header pipe extremely close to the engine for maximum of mass centralization and minimum exposure to rocks. At the noise-making end, a short, compact silencer is crafted from lightweight aluminum and finished in a unique SIX DAYS anthracite color, proudly displaying the SIX DAYS logo.
TOP-SHELF COMPONENTRY
The first KTM bearing the SIX DAYS name tore onto the scene way back in 1996. Almost 30 years later, we're still keeping that legacy alive. All KTM SIX DAYS models receive the full SIX DAYS treatment, from machined orange anodized triple clamps, right down to a solid rear brake disc. Each and every element on a SIX DAYS model is specifically chosen for the job at hand, stamped with a coveted SIX DAYS logo, and let loose to dominate the field.
FRAME
Specifically engineered for longitudinal rigidity, the KTM EXC-F SIX DAYS range is engineered around a gloss-orange powder-coated frame providing exceptional rider feedback, energy absorption, and high-speed stability. This is achieved by the rotating masses in the frame along with a forged steering head connection. The footrest mounts also feature a slim design for less risk of hooking up. And when the ride comes to an end, a forged one-piece side stand ensures your enduro weapon stands proud.
SUBFRAME
An 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. This compact subframe design also boasts the the ability to bend and flex in the event of a crash, rather than break, with the subframe fully integrating electronic components, without any extra need for brackets, holders, or unnecessary fixtures.
WP XACT CLOSED-CARTIDGE FORK
A 48 mm WP XACT Closed Cartridge spring fork provides fast and consistent damping, with optimized oil flow. This means these forks ensure unmatched performance at every level. Fork protection rings also protect against dirt intrusion. But, best of all, the fork allows for full adjustment of compression and rebound without the need for any tools.
WP XPLOR SHOCK
Remaining a hallmark of KTM Enduro weaponry, an PDS rear shock concept improves the anti-squat behaviors of the chassis. This remains the most reliable and maintenance-friendly option for competitive enduro racing. Moreover, a lightweight WP XPLOR PDS rear shock takes charge at the rear. For 2025 the rear shock received updated settings, resulting in improved pressure balance within the shock. With consistent damping, as well as full adjustability thanks to easy-to-use hand clickers for adjustments on the fly, it remains the setup to beat.
WHEELS AND TIRES
The KTM 450 EXC-F SIX DAYS rolls on a set of high-strength SIX DAYS-branded GIANT alloy wheels coupled to CNC-machined hubs and aluminum nipples. These are wrapped in a set of ultra-grippy Metzeler 6 DAYS Extreme tires providing exceptional traction in all conditions.
STABILITY
The KTM EXC-F SIX DAYS range remains rock-solid at any speed thanks to a forged steering head connection and CNC-milled triple clamps. Made from high-grade aluminum, these feature optimally tuned steering stem stiffness, perfect alignment of the fork tubes, and precise geometry of the fork clamps to ensure highly responsive and smooth fork action - not to mention unwavering stability for those ultra-fast flat-out special stages.
LED HEADLIGHT
Lighting the way forward, the KTM EXC range features an LED headlight unit and light mask. The mask itself features triple clamp protection against roost and does away with the rubber mounting straps for improved fitment. Most importantly, the LED lighting unit provides serious illumination, making riding in the dark a completely new experience.
