2026 KTM 125 XC-W

FULL GAS

Looking to regain its title in the 125cc Junior Enduro classes, the KTM 125 XC-W represents the pinnacle of 2-stroke engine technology, aimed at ambitious junior enduro racers and hobby riders asking for a performance-focused machine - and first-place trophies.

*This is a competition-only model with no street-legal homologation.

01. PREPARATION MAKES PERFECT

SETTING THE SAG

ADJUSTABILITY

Getting READY TO RACE has never been easier. The KTM EXC 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 GEAR

SWITCHGEAR

The entire KTM Enduro range comes with an easy-to-use switchgear. On the right side of the handlebar, you'll find a sleek start/stop switch, and on the left, an optional Map Select switch will allow riders to choose between Map 1 or Map 2.

IN MOLD

GRAPHICS

The KTM Enduro Range gets a fresh color update. Orange dominates the color palate, but shades of dark purple and red make an appearance, creating a unique, but ultra-READY TO RACE look. As always, all graphics remain in place thanks to in-mold technology, while the seat features a high-grip seat cover in black, with the same texture shared across the frame protectors, tank spoilers, and the bar pad.

02. BENCHMARK

TORQUE ABOUT IT

ENGINE

The KTM 125 XC-W boasts all the same engine innovations that have been brought into the 2-stroke realm. The engine is designed to centralize rotating mass for optimal operation with the chassis resulting in a light and agile handling feel, together with the benefits of mass centralization and reduced weight.

FUELING SPEED

THROTTLE BODY INJECTION

The ​KTM ​2-stroke ​Enduro models ​feature​ electronically​-controlled Throttle Body Injection​ - or TBI. The ECU​​, together with ​a 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. A 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.

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 is available as an optional extra on all KTM XC-W 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 125 XC-W 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 125 XC-W's 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.

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. An optional radiator fan can also be fitted for additional cooling.

03. ON THE CHARGE

BUILT TO BE THE BACKBONE

FRAME

Specifically engineered for longitudinal rigidity, the KTM Enduro 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. 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 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. 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 Enduro line-up rolls on a set of high-strength GIANT alloy wheels coupled to CNC-machined hubs and aluminum nipples. These are wrapped in a set of ultra-grippy Maxxis MaxxEnduro tires providing exceptional traction in all conditions.

04. KEEPING YOU GOING

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.
