Details

2021 KTM 250 SX-F
The KTM 250 SX-F was primed for global domination and is set to continue its dominance for 2021. Not only is it the lightest bike in its class, but it also offers an unrivalled, confidence-inspiring power delivery, making it a great choice for both amateur and professional riders. Laying the power down effectively is the secret to fast lap times and this capable package has all the right credentials to get the most important job done - getting to the chequered flag first.

ENGINE
Renowned as the strongest engine in 250 competition, the 2020 version maintains its dominance. Its compact structure contributes to excellent mass centralization, which supports the east rideability of the bike. The 2020 model features a new, stronger oil pump intermediate gear that, along with several other small, but important refinements, contributes to improved reliability. The low weight of only 57.1 lbs, in combination with the compact engine layout and unrivalled power, once again makes the KTM 250 SX-F a real force to be reckoned with, yet still easy to ride for both amateur and professional riders.
