Adjustability

Getting READY TO RACE has never been easier. The 2025 KTM 300 EXC SIX DAYS 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.

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.

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.

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.

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 2-stroke range, the KTM 300 EXC 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

Binging the Braaap! Thanks to the KTM 300 EXC SIX DAYS 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 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 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 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
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.

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.
