KTM 250 EXC-F 2017 — Specifications

When KTM decides to redesign one of its enduro flagships, it doesn't do things by halves. The 2017 version of the KTM 250 EXC-F marks a clean break from what came before: a completely revised engine, a refined chassis, onboard electronics. At €9,500, this 248.6 cc four-stroke single isn't aimed at weekend tourists. It's built for riders who know their terrain, who read the landscape before attacking it, and who demand a tool engineered for homologated competition.

The engine itself deserves a closer look. KTM shortened the internal architecture by 20 mm through a repositioning of the shafts, bringing the center of gravity lower and further back. The engine alone weighs in at 27.6 kg, 1.5 kg less than the previous generation. The 78 mm bore with a 52.3 mm stroke gives a character tuned for high revs, with a 12.8:1 compression ratio that demands clean fuel and careful Keihin engine management. The throttle body grows to 42 mm, throttle response is crisp without being brutal, and the optional map selector allows the engine character to be adjusted to suit the terrain. Up to 12,800 rpm, the single-cylinder delivers its 35 horsepower without flinching — a broad powerband for a 250 cc machine whose direct competitors, the Husqvarna FE 250 chief among them, play in the same register without necessarily outperforming the orange bike over time.

What truly sets the 2017 KTM 250 EXC-F apart from its predecessors is the integration of a Mitsuba electric starter paired with a 495-gram lithium-ion battery. For anyone who has ever tried to restart a hot four-stroke in a muddy hollow, knees in the water, this is a tangible difference. The WP Xplor 48 inverted fork with 300 mm of travel handles compression on one side, rebound on the other; adjustments are made with a screwdriver at 30 clicks, no disassembly required. At the rear, the WP PDS XPlor shock absorber — 600 grams lighter — operates without a linkage, mounted directly to the one-piece aluminum swingarm. The result on the ground is predictable traction and progressive feel that the KTM 250 EXC-F workshop manual describes in detail for those who want to fine-tune settings to their build.

The chromoly steel frame remains the EXC range's historical strong suit. Torsionally rigid, longitudinally supple, it absorbs impacts without transmitting stress to the rider's wrists. With a 1,482 mm wheelbase, 355 mm of ground clearance, and a 960 mm seat height, this is not a motorcycle for shorter riders. Those looking for a used KTM 250 EXC-F should check the condition of the seat and the aluminum WP radiator guards, which are often sacrificed on rocky courses. The 8.5-liter transparent polyethylene tank gives a reasonable range for a day of enduro — no more. The Brembo Wave disc brakes do their job cleanly, and the rear brake pedal, extended by 10 mm, improves modulation on tight descents.

Whether on a KTM 250 EXC-F 2008 picked up for track use or this 2017 model straight from the dealership, the philosophy hasn't changed in years: offer the lightest and most precise motorcycle in the 250 cc enduro segment, even at the cost of some comfort on long road transfers. Against a Yamaha WR250F or a Honda CRF250RX, the KTM takes a more aggressive, sharper stance, less oriented toward trail riding. That's not a flaw — it's a choice. Those looking to progress quickly in competition, or who want a solid platform to prepare for national events, will find in this 250 EXC-F a motorcycle that doesn't forgive imprecision but generously rewards precise riding.
