Enhanced 2021 KTM SX-F and SX motocross models unveiled
Make adjustments with advanced myKTM app using Connectivity Unit kit.
KTM has taken the covers off its 2021 motocross range, featuring enhancements that have flowed through from research and development of the Austrian brand’s factory racing teams that make for the most technically-advanced, ‘Ready To Race’ range to date.
The feedback collected by racing achievements globally helped KTM R&D update the KTM SX model range for 2021 with clear core objectives, to create the lightest, best-handling, most powerful, usable and well-equipped motocross bikes.
Improvements for 2021 across the full-size range focus on suspension and chassis modifications, tweaks to engine architecture to further enhance reliability, new Dunlop tyres 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.
As the flagship model in the four-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 personalise 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.
As a towering example of power-to-weight ratio excellence in the KTM two-stroke range, the 2021 KTM 125 SX is boldened with a fresh piston and clutch internals, with the treatment extending to the 250cc-challenging KTM 150 SX.
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 and 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 information, visit www.ktm.com.
