Renowned for its inebriating top-end powerband, the 2025 KTM 250 EXC SIX DAYS continues as the ultimate enduro screamer. Being the poster child for KTM's unrelenting commitment to 2-stroke development, it has refined its winning recipe with learnings directly from the highest echelons of racing and put them into a rider-centric package. In short – its READY TO RACE.
.
2025 KTM EXC SIX DAYS RANGE highlights are:
Engine
The 250cc 2-stroke engine has long been the best combination of unsurpassed power and lightweight construction. This lightweight 24.8 kg engine is designed to provide more torque than any previous 250cc 2-stroke engine without losing its typical 250 cc 2-stroke charactet. The KTM 250 EXC engine sets the benchmark in the competitive Enduro E1 class.
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.
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 is available as an optional extra on all 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 KTM EXC range, the KTM 250 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.
