ENGINEERED FOR EXTREMES: KTM LAUNCHES THE 2026 KTM 300 XC-W Hardenduro
With Manuel Lettenbichler already well on his way to his 5th Enduro World Championship, his weapon of choice needs little introduction. However, for 2026, the KTM 300 XC-W HARDENDURO boasts key updates, with suspension, cooling, and overall design receiving significant refinements, set to take its domination of torturous terrain even further.
Since its launch in 2024, the KTM 300 XC-W HARDENDURO has become the premier model in the KTM Enduro lineup, bringing Factory Racing expertise and championship-winning pedigree directly to the dealership floor.
Being the ultimate in Enduro Competition motorcycles, the 2026 KTM 300 XC-W Hardenduro receives a fresh graphics package, which features the typical KTM orange color accentuated by a white and black color palette, a gloss orange frame, and signature orange anodized KTM PowerParts.
However, it is updates to the hardware that will XC-Wite hardcore racing fans the most, starting with updates to the 48 mm WP XACT Closed Cartridge fork, including the preload basevalve adjusters and an updated WP XPLOR PDS rear shock to keep things in balance.
The fork receives new damping settings and new, lighter, shorter springs, as well as a new pressure reservoir that has been adapted to the new geometry of the spring support. A new one-piece hydro stop rounds out the updates to the front fork, which also results in an overall weight saving of 200 grams.
On the fueling front, a new protection cap is added to the CPC fuel connector, which not only provides added protection against any outside damage but also prevents dirt from entering the sides of the connector.
The cooling system has also received some upgrades by way of a new radiator cap with a standard thread, allowing for easier and faster opening, with a radiator fan fitted as standard equipment.
2026 KTM 300 XC-W Hardenduro Totalmotorcycle.com Features and Benefits
SETTING THE SAG
Adjustability
Getting READY TO RACE has never been easier. The KTM XC-W 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 secure and accurate filter installation. All this ensures the air filter is easily accessed, without tools, for fast trail-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 sleek start/stop switch, and on the left, a Mapping Select switch will allow riders to choose between Map 1 or Map 2 – standard on the HARDENDURO.
UNMISTAKABLE
Graphics
This is one graphics package you won’t want to swap out! The KTM 300 XC-W HARDENDURO boasts striking striped black-on-white spoiler graphics setting off the signature orange frame and rear fender.
SMARTER ELECTRONICS
Offroad Control Unit
An 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.
FUELING SPEED
Throttle Body Injection
The KTM 2-stroke Enduro models feature electronically-controlled Throttle Body Injection – or TBI. The ECU, together with a new Keihin 39 mm 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. A new protection cap is used for the CPC fuel connector on all models. This not only prevents dirt from entering the sides of the connector and prevents mistakenly opening, but also adds protection from sticks or stones that might hit it. The small fuel filter in the fuel hose still stays in place and is easily accessible.
PICK YOUR POWER
Selectable Engine Maps
Designed for easy operation, the map select switch comes standard on the KTM 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.
LITHIUM POWERED
Battery & Wiring Harness
As with the rest of the 2-stroke XC-W range, the KTM 300 XC-W 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.
FLUID RIDER MOTION
Ergonomics
The KTM XC-W 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 XC-W HARDENDURO’s compact engine design, 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, saving weight and provides the signature low-down 2-stroke burble for this rock-hopping hero.
HARDENDURO EQUIPMENT
Top-shelf Componentry
The KTM 300 XC-W HARDENDURO models receive the full hard enduro treatment. From the standard-fitted radiator fan to machined anodized triple clam, right down to a solid rear brake disc, with safety wire, each and every element on a HARDENDURO model is specifically chosen for the job at hand.
COOL HEADED
Cooling System
Keeping cool is made even easier, thanks to a new 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.
BUILT TO BE THE BACKBONE
Frame
Specifically engineered for longitudinal rigidity, the KTM 300 XC-W HARDENDURO 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.
Handlebars
Held in place by a set of CNC-machine triple clamps, the handlebar on the KTM 300 XC-W HARDENDURO features a unique bar pad and soft, gray, ODI lock-on grips for ultimate control. A set of wrap-around handguards provides further protection from unwanted obstacles in your path.
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. This means these forks ensure unmatched performance at every level. But, best of all, the fork allows for full adjustment of compression and rebound without the need for any tools.
GET THE POWER DOWN
WP XACT Shock
Remaining a hallmark of KTM Enduro weaponry, a 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. 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.
WHERE RUBBER MEETS DIRT
Wheels and Tires
The KTM 300 XC-W HARDENDURO rolls on a full-factory wheelset made up of high-strength black alloy wheels coupled to orange-anodized CNC-machined hubs, black spokes, and orange aluminum nipples. These are wrapped in a set of ultra-grippy Dunlop AT 82 tires providing exceptional traction in all conditions.
STOPPING POWER
Brakes
Slowing the KTM 300 XC-W HARDENDURO comes courtesy of a floating front brake disc and solid brake disc on the rear. Not only does the latter provide increased pad life and heat dissipation, its also safety wired directly from the factory. Both ends also get brake protection as standard, with a composite front brake disc guard and orange anodized rear disc guard as standard.
HOLD THE LINE
Stability
The KTM XC-W 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
Seat
Swing your leg over the KTM 300 XC-W HARDENDURO and you’re met with a diamante Facotry seat, wrapped in a back seat cover with transversely stitched ribs, and protected by a water-resistant coating, you can be assured of maximum grip alt all times, with unrestricted freedom of movement when you need it.
SEE INTO THE FUTURE
LED headlight
Lighting the way forward, the KTM XC-W 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.
