KTM 250 SX-F Factory 2017 — Specifications

When KTM releases a Factory Edition, it's not for show in a catalog. It's a statement of intent addressed directly to professional teams and riders who want zero compromise between their production bike and what the MX2 stars are racing. The 2017 250 SX-F Factory follows this uncompromising logic, with 98.5 kg dry on the scale and 45 horsepower extracted from a 249.9 cc single-cylinder engine machined from solid, with a 78 mm bore and 52.3 mm stroke, compression ratio at 14.4:1. The power-to-weight ratio is brutal, immediate, non-negotiable.

What sets this Factory version apart from the standard model is the attention paid to every peripheral component. The 48 mm WP inverted fork delivers 310 mm of travel, the steering yokes are machined from anodized aluminum, and the FMF titanium silencer further reduces rear-end weight. The D.I.D. DirtStar rims complete the picture of a spec sheet that, at the time, was found directly on bikes entered in world championship competition. This isn't marketing: the Red Bull KTM Racing and Troy Lee Designs teams were genuinely racing on this platform in 2017, which explains the extremely limited availability of the machine in certain markets such as North America.

Against the Husqvarna FC 250 — its close cousin sharing the same Austrian platform — the SX-F Factory distinguishes itself primarily through its premium component specification and exclusive graphic livery, Red Bull KTM or Troy Lee Designs at the buyer's choice, on a painted orange steel tube frame. The Yamaha YZ250F and Honda CRF250R compete in the same category, but neither offered in 2017 a factory-spec level of equipment this close to the competition world. The 960 mm seat height and 7-liter fuel tank are further reminders that this motorcycle is built for the short track and lap time management, not enduro or trail riding.

The target audience is clearly defined: the seasoned motocross rider, licensed or highly informed amateur, who wants to skip the usual preparation costs by buying a fully sorted machine from the outset. At €9,500, the price tag is steep compared to a standard SX-F, but the Factory parts included justify the premium for anyone planning to ride seriously. This is not the bike for a beginner looking for a 250 to learn motocross. It is a competition tool dressed for victory, produced in limited numbers, whose more recent iterations such as the ktm 250 sx-f factory edition 2022 and the 2024 ktm 250 sx-f factory edition have continued to refine the recipe by integrating electronic and suspension developments with each model year.

The 2017 250 SX-F Factory remains today a reference point for understanding how KTM systematized the concept of the near-works bike available for retail purchase. Its dynamic qualities have not aged on track, even if the 2023 and 2025 versions have since gained in electronic management and mass optimization. For anyone searching for a ktm 250 sx-f factory edition for sale on the used market, this model year represents a serious entry point into a level of performance that few production motorcycles could match at the time.
