CONSULTATION with elite racers and feedback from customers has helped KTM develop a raft of performance updates across its 2021 SX model line-up, with the new range representing a massive step forward.
KTM has utilised the technical research gained through its dominance in motocross and supercross races to enhance its entire SX range, including tapping into the success Cooper Webb and Jorge Prado.
It allowed KTM to focus on two core objectives for 2021; to create the lightest, best-handling, most powerful, usable and well-equipped motocross bikes available, and to ensure that riders of any age or ability will find the exact technical package they require.
Improvements across the full-size range focus on suspension and chassis modifications, tweaks to engine architecture to further enhance reliability, new Dunlop tyres in the form of Geomax MX33, 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.
Its flagship 4-stroke model, 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 optional connectivity kit.
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.
As a towering example of power-to-weight ratio excellence in the KTM 2-stroke range, the 2021 KTM 125 SX is emboldened with a fresh piston and clutch internals, with the treatment extending to the 250 cc-bothering KTM 150 SX.
In addition, 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 score 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 handlebars, 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. A range of parts and accessories are also available to further enhance the KTM SX and Sportminicycles ranges.
The 2021 KTM SX range will be available at KTM dealers in Australia and New Zealand from October 2020 on-wards.
