2021 250 SX-F KTM Dirt Bike was built to take the world by storm and continue to do so until 2021. Aside from its low weight, this bike has an unmatched power delivery that will inspire riders of all skill levels to take the road more confidently. The key to quick lap times is laying the power down properly, and this competent package has all the qualities to get the essential job done — winning the race.
In terms of power delivery and performance, the exhaust on all 4-stroke versions delivers a punch that can’t be beaten. You’ll find an FDH (Flow Design Header) small chamber surrounding the pipe in a model-specific header pipe. Since the shock absorber does not need to be removed, this design makes it easier to service the shock. Slimmer design is possible thanks to the aluminum sleeve and end cap, as well as the silencer’s internal structure.
