Segment: Enduro/Offroad

For model year 2018 all models receive a generation changing update with KTM engineers targeting a further weight reduction that once again sets a clear benchmark in each class.

In fact, in the higher capacity 450cc segment the KTM 450 SX-F is a lot lighter than its rivals.
All models in the KTM SX range have received major engine revisions over previous models. The KTM 250 SX-F and KTM 350 SX-F models enjoy a newly designed DS clutch, while all 4-strokes boast revised transmissions and a state-of-the-art Keihin engine management system with a reworked throttle body and improved electronics package.
