KTM 250 SX-F 2022 — Specifications

Ninety-nine kilograms on the scale dry, 45 horsepower unleashed by a 249.9 cc single-cylinder, a seat height of 950 mm that immediately puts the rider in attack position. The KTM 250 SX-F doesn't try to convince on paper — it makes its case on hard-packed dirt, in the noise and dust of motocross tracks. And on that specific terrain, few machines dare to match 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 rocker arms 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 throttle opening. 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 chromoly steel 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 — high and low-speed compression for the rear, compression and rebound with 30 clicks for the front — places the bike in a category of its own in terms of setup precision. The one-piece die-cast swingarm allows wheelbase adjustments to suit different track configurations. The 260 mm Brembo Wave disc up front and 220 mm at the rear complete a braking package that responds precisely without ever biting brutally.

The electronics on the KTM 250 SX-F 2020 deserve mention 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 overall weight. For those looking for a used KTM 250 SX-F or hesitating between model years, this electronic evolution is a genuine argument over earlier versions.

The only point on which one can remain measured concerns the 7-liter fuel tank, consistent for purely competitive use but limiting in the context of extended recreational riding. The 950 mm seat height also demands a suitable build, which clearly orients this model toward already experienced riders rather than beginners looking for their first motocross bike. Priced at €9,499, the KTM 250 SX-F positions itself at the top of the MX2 segment, on par with its premium Japanese rivals, but with a level of out-of-the-box preparation that other brands don't offer without a second trip to the cashier.
