First Look: 2019 KTM Motocross Range

6 months ago

A new generation of motocross technology is here with the KTM SX 2019 range. These all-new machines have been radically redefined. And not just the big bikes, the junior machines as well. These new MXers are currently being launched and tested at the home track of KTM’s Champion, Tony Cairoli, in Malagrotta, Italy by Transmoto’s Andy Wigan. But before we break down these bikes into greater detail, here’s a top-line insight into the upgrades for 2019…



For 2019, all full-size models (125cc & up) receive a generation-changing update with KTM engineers targeting a further weight reduction that once again sets a clear benchmark in each class. All SX models feature a re-worked frame for improved stiffness, handling and straight-line stability, a longer subframe, a revised rear axle slot and all-new bodywork for enhanced ergonomics with more freedom of movement. A brand-new appearance with new graphics complements a newly-shaped seat and new fuel tank. A new air filter box offers improved protection of the air filter and better airflow with revised exhaust systems for both the two-strokes and four-strokes that contributes to a more efficient power delivery and improved performance.
New radiators offer efficient cooling with improved positioning for mass centralisation, while a stronger lithium-ion battery for the ‘E-starter’ is harmonious with the re-worked wiring harness for a compact electrical system. An updated triple clamp system for improved handling complements new suspension settings, while a newly-developed, dual purpose, plug-in stand is yet another feature of the new range. All models continue to enjoy impressive serial components such as Brembo brakes, WP suspension, Neken handlebars, Dunlop tires, plus a map select switch with integrated traction control, launch control and map selection on the four-stroke machines. This is no refinement model year, it’s an evolution; around 60% of each bike’s components are new.


All models in the KTM SX range have received major engine revisions over previous models. The KTM 250SX-F and KTM 350SX-F models enjoy a newly designed DS clutch, while all four-strokes boast revised transmissions and a state-of-the-art Keihin engine management system with a reworked throttle body and improved electronics package. The KTM 125SX, KTM 150SX, and KTM 250SX all offer revised carburetor settings, with a new transmission and new clutch in each amongst other improvements. In addition to engine refinements on all models, the highlight KTM 450SX-F model enjoys a newly developed SOHC cylinder head for reduced weight and improved mass centralisation, a new camshaft with a shorter valve timing and the improved surface along with a low-friction chain guide with a DLC coating.

Stay tuned for more on KTM’s new 2019 machines dropping soon…
