A reworked range of KTM SX machines has been announced! Dirt Action’s Danny Ham is currently in Rome, Italy riding these awesome machines. In the meantime, here is a run down of the updates for 2019.
Chassis
For model year 2019, all adult models receive a generation-changing update with KTM engineers targeting a further weight reduction that once again sets a clear benchmark in each class. In fact, in the higher capacity 450cc segment the KTM 450 SX-F is a lot lighter than its rivals. 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 compliment a newly-shaped seat and new fuel tank. A new air filter box offers improved protection of the air filter and better air flow with revised exhaust systems for both the 2-strokes and 4-strokes that contributes to a more efficient power delivery and improved performance.
New radiators offer efficient cooling with improved positioning for mass centralization, 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 compliments 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 handlebar, Dunlop tires, plus a map select switch with integrated traction control, launch control and map selection on the 4-stroke machines. This is no refinement model year, it’s an evolution; around 60% of each bike’s components are new.
Engine
All models in the KTM SX range have received major engine revisions over previous models. The KTM 250 SX-F and KTM 350 SX-F models enjoy a newly designed DS clutch, while all 4-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 125 SX, KTM 150 SX and KTM 250 SX 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 450 SX-F model enjoys a newly developed SOHC cylinder head for reduced weight and improved mass centralization, a new camshaft with a shorter valve timing and improved surface along with a low-friction chain guide with a DLC coating.
For those looking to intensify their ride and fine tune their machines to their own individual requirements, KTM has created a full range of aesthetical and performance parts available in its KTM PowerParts collection. Developed in parallel to the new SX generation from conception to production, and by some of the finest engineers in the world at KTM in conjunction with leading accessories manufacturers, this wide choice of products can certainly take each SX model to new heights. Not only that, the KTM PowerWear range provides a diverse catalog of READY TO RACE, high-quality products for those gearing up for the toughest of battles. With protective gear, riding wear and casual wear on offer, riders can look great both on and off the track.
