2020 KTM two-strokes break cover

The new 250SX with updated suspension

It might only be the end of April but KTM’s new 2020 250SX, 150SX and 125SX have been leaked, showing suspension upgrades and new-look graphics, while the black frame and black Excel rims of the all-new 2019 models remain. All still use carbs rather than switching to fuel injection, as on the 250 and 300 enduro bikes.

All new graphics feature on the new bikes, like this 250

All the new bikes get updated WP XACT air forks with revised internals and new settings. The rear WP XACT shock has a new compression damping adjuster and new settings.

The 150 is always popular

The only other change is thought to be on the 125 which gets a change to how the front sprocket is held on. A bolt and diaphragm spring have replaced last year’s circlip.

The 150 is like a 125 for grown ups!

The bikes had a full overhaul last year, hence the few changes for 2020. It’s though the four-stroke KTMs will also get similar changes. There is no news on price or availability, but the two-strokes should go on sale in the next couple of months.

The 125 gets a new front sprocket fixing mechanism

It’s believed the KTM enduro range will get a major overhaul for 2020.

The 125 gets new suspension and graphics
