2021 KTM 250 SX-F [Model Overview]

The 2021 KTM 250 SX-F: The Fastest In Its Class, Now With A Four-Stroke

The 2021 KTM 250 SX-F is a true competitor, from the rawness of its power to the lightness of its frame. It’s been so successful as a two-stroke, that the European manufacturer put in the time and engineering to make a four-stroke version of the engine and bike for the 2021 model year, known as the 250 SX-F. The 250cc engine, like its 250 SX counterpart, makes just around 50 HP.

KTM has definitely done their homework, however, in separating the bikes between classes. The 250 SX-F four-stroke is more for the longer courses of supercross, and is able to participate in endurance rallies without much trouble. It can also go faster overall than the SX version, although it won’t get to its top speed quite as fast. The last key difference is that the SX-F has an electric starter, while the SX is kickstart only.

KTM Motorcycles kept the same chassis but with a few tweaks so that the bike can compete in several different forms of bike sport with the word “cross” as part of its name, be it motocross, supercross, or cross country. As with almost all KTM motocross bikes, it comes with WP racing suspension, disc brakes, and a 5-speed manual transmission with hydraulics by Brembo.

The 2021 KTM 250 SX-F starts at $9,299 USD / $10,599 CAD.
