Noumerous updates are in place to optimize performance further and provide distinctive style and aesthetics in honor of the event form the 2026 KTM EXC 6DAYS line-up. READY TO RACE infuses KTM’s Enduro engineering but the KTM 6DAYS is pure expression of the tech and trend necessary to pull away from the pack and look cool while doing so at the oldest FIM offroad contest there is.
THE MOMENT: The 2025 6DAYS FIM Enduro of Nations (formerly the ISDT or ISDE for International Six Days Enduro) will churn terrain around the northern city of Bergamo, Italy for a week at the end of August and KTM will again have a prominent presence in the 99th incarnation of this famous annual fixture. Italy, the UK, the USA and France have claimed the prestigious World Trophy since the turn of the decade and more KTM-equipped athletes will be probing for personal and team glory come the launch on 24 August.
THE MACHINERY: 2026 KTM EXC 6DAYS editions include the KTM 300 EXC 6DAYS (2-stroke) and KTM 250 EXC-F 6DAYS, KTM 350 EXC-F 6DAYS, KTM 450 EXC-F 6DAYS and KTM 500 EXC-F 6DAYS (4-strokes).

2026 KTM 300 EXC 6DAYS Totalmotorcycle.com Features and Benefits
SETTING THE SAG
Adjustability
Getting READY TO RACE has never been easier. The KTM Enduro 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.
DEEP BREATH
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.
FULLY FUELED
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.
SWITCH IT UP
Switchgear
On the right side of the handlebar, you’ll find a 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 6DAYS models.
ISDE24 INSPIRED
Graphics
The KTM 6DAYS range sends a high-flying salute to the ISDE Italia, with striking graphics incorporating the colors of the Italian flag, a glossy orange frame, and striking blue finishes.
TORQUE ABOUT IT
Engine
The 300cc 2-stroke powerplant not only brings choice into the E3 Enduro category but remains the ideal 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 hard enduro races all over the world.
FUELING SPEED
Throttle Body Injection
The KTM 2-stroke Enduro models feature electronically-controlled Throttle Body Injection – or TBI. The ECU and Keihin 39mm throttle bodycalculate the ideal air-fuel mixture by constantly analyzing different parameters. A protection cap is used for the CPC fuel connector on all models to add additional layer of protection. While a small fuel filter in the fuel hose stays in place and is easily accessible.
SMARTER ELECTRONICS
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.
PICK YOUR POWER
Selectable Engine Maps
Designed for easy operation, the map select switch comes standard on the KTM EXC 6DAYS 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.
LITHIUM POWERED
Battery & Wiring Harness
As with the rest of the 2-stroke Enduro range, the KTM 300 EXC 6DAYS 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.
FLUID RIDER MOTION
Ergonomics
The KTM Enduro 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.
UNMATCHED PERFORMANCE
Exhaust
Binging the Braaap! Thanks to the KTM 300 EXC 6DAYS compact engine, the header pipe is designed with the target of achieving more ground clearance and reducing the risk of damage when riding over deep roots, ruts, or climbing steep rocks. The silencer is crafted from lightweight aluminum and is stylishly finished off in anthracite, featuring the 6DAYS logo.
6DAYS EQUIPMENT
Top-shelf Componentry
The first KTM bearing the 6DAYS name tore onto the scene way back in 1996. Almost 30 years later, we’re still keeping that legacy alive. All KTM 6DAYS models receive the full 6DAYS treatment, from machined orange anodized triple clamps, right down to a solid rear brake disc. Each and every element on a 6DAYS model is specifically chosen for the job at hand, stamped with a coveted 6DAYS logo, and let loose to dominate the field.
COOL HEADED
Cooling System
Keeping cool is made even easier, thanks to a radiator closure with a standard thread opening. This makes it quicker and easier to open the radiator cap for top-ups. For additional cooling, a radiator fan is fitted as standard equipment across the 6DAYS model range.
BUILT TO BE THE BACKBONE
Frame
Specifically engineered for longitudinal rigidity, the KTM EXC 6DAYS range is engineered around a gloss-orange powder-coated frame providing exceptional rider feedback, energy absorption, and high-speed stability. This is achieved by repositioning 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.
MORE THAN A SUBFRAME
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.
UNFLAPPABLE FRONT END
WP XACT Closed-cartidge Fork
The proven 48 mm WP XACT Closed Cartridge fork has been updated with shorter, lighter main springs with a polished surface, which improves durability and reduces weight by 200 grams.
GET THE POWER DOWN
WP XPLOR Shock
Remaining a hallmark of KTM Enduro weaponry, the 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.
WHERE RUBBER MEETS DIRT
Wheels and Tires
The KTM 300 EXC 6DAYS rolls on a set of high-strength 6DAYS-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.
HOLD THE LINE
Stability
The KTM Enduro range remains rock-solid at any speed thanks to a repositioned and 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.
SEE INTO THE FUTURE
LED headlight
Lighting the way forward, the KTM Enduro range features an LED headlight unit and light mask. The mask itself features improved 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.
