Inside the 2021 KTM 250 SX-F
For the second year in a row, the KTM 250 SX-F enjoys a few targeted refinements rather than a complete overhaul, but that’s not necessarily a bad thing as the orange ripper was one of the most potent bikes in its class in 2020. The tried and true engine package returns completely unchanged, but some well-planned suspension refinements on both ends of the WP package give the 250 SX-F a more comfortable, controlled feel on the track. We caught up with KTM’s Nate Abelia to get the rundown on the updates.
The updated WP Xact fork has new internals that features extended oil and air bypass to reduce pressure peaks, while a new mid-valve damping system is intended to provide improved control for greater feedback and feel. A smaller rebound spacer in the air leg increases the tube;’s air volume in the negative chamber for a more linear air spring curve, which emulates the feel of a mechanical spring while maintaining the performance advantages of air.
Out in back the reworked Xact shock has a new o-ring in the link piston and high-quality SKF seals to reduce fading and ensure consistent suspension performance. Both ends of the suspension have been revised with slightly stiffer settings for 2021 that keep the 250 SX-F riding higher in the suspension stroke, where dampening is more compliant and plush..
