Overview
When KTM decides to put 103.5 kg on a scale and graft a 250 cc fuel-injected single-cylinder onto it, the result is called the KTM 250 EXC-F 2020, and it seriously reshuffles the deck in its category. Since its earliest versions, the KTM 250 EXC-F has always carried its reputation as the Swiss Army knife of enduro: light, responsive, accessible to developing riders without leaving experts behind. The 2020 model takes the exercise even further, with a fully revised chromoly steel frame and refined WP Xplor suspension tuned to match the chassis updates.

The engine is where everything is decided. The 249.9 cc four-stroke single produces 35 horsepower, which looks modest on paper against a Husqvarna FE 250 or a Beta RR 250 4T, but raw power isn't the point here. The 78 mm bore with a 52.3 mm stroke defines a short-stroke-oriented engine, snappy and eager to rev. The 12.8:1 compression ratio, paired with the 42 mm Keihin fuel injection, produces a linear and easily modulated power curve, which corresponds precisely to what a rider building their speed needs. The DOHC cylinder head with its titanium valves and DLC-coated rocker arms minimizes friction at high rpm; the crankshaft repositioned toward the center of gravity shortens internal distances and improves responsiveness on the exit of tight corners. Those wishing to further optimize their machine will find the KTM 250 EXC-F workshop manual useful before working on the KTM 250 EXC-F exhaust or adjusting engine mapping via the ECU.
The chassis deserves as much attention as the mechanics. The central frame with automatically welded hydroformed tubes adopts increased torsional rigidity, with aluminum cylinder head mounting brackets that better absorb vibrations and refine trajectory in technical sections. The WP-USD Xplor 48 mm separate-circuit fork remains the reference in its category: compression on the left, rebound on the right, thirty adjustment positions on each leg. The PDS rear shock, linkage-free, simplifies the kinematics and reduces the risk of snagging on rocks. With 355 mm of ground clearance and a 960 mm seat height, the machine is aimed at riders of reasonable stature, actively progressing or already experienced, rather than beginners who have never left the tarmac. The 9-liter translucent polyethylene tank is sufficient for a standard enduro special stage, without being generous for long riding days.
At €10,299, the KTM 250 EXC-F 2020 sits at the top of its price segment. That is the price of a motorcycle directly derived from competition platforms, delivered with a Mitsuba electric starter powered by a 2 Ah lithium battery and Brembo brakes with Wave discs on both wheels. One can compare this weight-to-equipment ratio against a Yamaha WR250F or a Honda CRF250RX, but both Japanese machines remain less well-equipped on the electronics side, with noticeably less sophisticated engine management. The used KTM 250 EXC-F holds its value well on the secondhand market, reflecting buyers' lasting confidence in the platform's reliability, whether it is a KTM 250 EXC-F 2009, a KTM 250 EXC-F 2012, or more recent versions such as the KTM 250 EXC-F 2021 and the KTM 250 EXC-F 2022. That is a compelling argument for anyone hesitating between new and a well-maintained used example.
What this machine fully owns is its identity as a homologated competition bike. It does not have the low-end tractability of a versatile trail bike, nor the comfort of a mid-size adventure. On the other hand, on a marked trail, in a timed stage, or during a club enduro outing, the KTM 250 EXC-F finds its register with a precision that leaves little room for criticism. The intermediate rider looking to progress quickly, the seasoned enduro rider seeking a light and easily configurable machine: those are the two profiles for which this motorcycle was built, without compromise.
