KTM gives new reason for competitive motocross (MX) riders to look into their 2021 SX model range. Just a few days ago, this lineup was launched through an online presentation.
According to KTM, they have collected data from their winning stable of motocross riders, using that data to further improve the SX. This line of track-only MX bikes aims to be the lightest, best-handling, most powerful, usable and well-equipped motocross bikes.
2021 KTM SX-F 250
Improvements for 2021 across the full-size range focus on suspension and chassis modifications, tweaks to engine architecture to further enhance reliability, new Dunlop tires, and a reworked graphics aesthetic. The WP XACT front forks and rear shocks have been overhauled with new components as well as being reconfigured with a slightly firmer standard-setting to increase confidence and comfort across a wider spread of surfaces. Dunlop’s Geomax MX-33 is the rubber of choice for the KTM SX models thanks to its versatility and race-proven performance.
4-stroke
KTM 450 SX-F
As the flagship model in the 4-stroke range, the KTM 450 SX-F benefits from modifications to the piston, crankshaft, engine casing, rocker arms, and shift locker to further hike the bike’s excellent reliability, shave more weight and aid practicality in terms of general maintenance.

In addition, the 2021 KTM 450 SX-F together with the new KTM 350 SX-F and KTM 250 SX-F machines can connect with the advanced myKTM app using an extra Connectivity Unit kit - available in the KTM PowerParts catalog. With the bar-pad-integrated Connectivity Unit fitted and the myKTM app installed, riders can personalize their KTM SX-F according to their preferences and track conditions without technical assistance. Offering the finest technical touch, the myKTM app allows for a wide spectrum of adjustability on the fly, a privilege that was limited to elite KTM factory riders until recently.
2-strokes
KTM 125 SX
As a towering example of power-to-weight ratio excellence in the KTM 2-stroke range, the 2021 KTM 125 SX is boldened with a fresh piston and clutch internals, with the treatment extending to the KTM 150 SX, giving it power close to a 250 cc.
KTM treats its Sportminicycle roster with the same ground-up priority for development as the full-size bikes. The KTM 85 SX, KTM 65 SX and KTM 50 SX & KTM 50 SX MINI, therefore, count on a new throttle assembly for better and smoother throttle action. For the KTM 85 SX, braking potential is much higher thanks to larger discs and a completely new front and rear brake system made by FORMULA. All three junior motocrossers now have a tapered handlebar allowing fitment of ODI lock-on grips. For the KTM 50 SX and KTM 50 SX MINI, the new tapered handlebar allows fitment of thinner grips.
The 2021 KTM SX range will become available at KTM dealers worldwide from June 2020 onwards. For more info visit www.ktm.com.
