KTM 250 SX-F 2020 — Specifications

Ninety-nine kilograms on the scale dry, 45 horsepower released by a 249.9 cc single-cylinder engine, a seat height of 950 mm that places the rider in an attack position from the outset. The KTM 250 SX-F doesn't try to convince on paper — it makes its case on the dirt, in the noise and dust of motocross tracks. And on that specific terrain, few machines dare to stand their ground against it.

What sets this engine apart from its direct rivals, the Yamaha YZ250F and the Honda CRF250R, is the density of its architecture. The DOHC four-valve-per-cylinder unit, with a bore of 78 mm and a stroke of 52.3 mm, displays a compression ratio of 14.4:1 that leaves no ambiguity about its intentions. Add to that titanium valves actuated by DLC-coated finger followers to reduce friction, a 44 mm Keihin fuel injection system managed by an ECU that reads the engaged gear in real time, and you get an engine that responds with disarming directness at every twist of the throttle. The KTM 250 SX-F 2020 pulls hard, certainly, but it pulls with a readability that amateur riders will appreciate just as much as professionals.

The hydroformed chrome-molybdenum tubular frame works in direct synergy with the 48 mm inverted WP fork, adjustable over 310 mm of travel, and the rear WP monoshock with 300 mm of travel. This fully adjustable suspension duo — with high and low-speed compression adjustment at the rear, and 30-click compression and rebound at the front — places the bike in a class of its own in terms of setup precision. The die-cast single-piece swingarm allows wheelbase adjustments to accommodate different track configurations. The 260 mm front and 220 mm rear Brembo Wave discs round out a braking package that responds with precision without ever biting brutally.

The electronics on the KTM 250 SX-F 2020 deserve to be mentioned without condescension. The handlebar-mounted map selector allows switching between two power curves, activating traction control on wet sections, or engaging launch control from the gate — a feature reserved for Supercross machines just a few years ago. The Mitsuba electric starter, powered by a 2 Ah lithium-ion battery, has become indispensable in competition, and KTM has managed to integrate it without penalizing the overall weight. For those looking for a used KTM 250 SX-F or hesitating between model years, note that this electronic evolution is a genuine argument over earlier versions.

The only point on which one might remain measured concerns the 7-liter tank, which is coherent for purely competitive use but limiting for extended recreational riding. The 950 mm seat height also demands a suitable build, which clearly steers this model toward already experienced riders rather than beginners in search of their first motocross bike. Priced at €9,499, the KTM 250 SX-F positions itself at the top of the MX2 segment, on the same level as its premium Japanese competitors, but with a level of factory preparation that other brands do not offer without a second trip to the cashier.
