POWER SUPREMACY

The championship winning KTM 450 SX-F is a proven formula that is the industry benchmark. For 2019, this new machine takes the next step in efficient performance and easy handling. It is fitted with a newly designed, extremely compact, single overhead camshaft cylinder head, as well as the latest electronic fuel injection. Pushing out an unrivalled 63hp in the most effective way possible, this 450 cc is the fastest Motocross bike KTM has ever built.

ENGINE & EXHAUST

The 450cc engine is the ultimate powerhouse when it comes to KTM's competitive motocross range. Significantly reworked for 2019, it features even more compact dimensions and reduced weight. It is fitted with a newly designed, extremely compact single overhead camshaft cylinder head and the latest electronic fuel injection. This enables the impressive 63hp to be distributed extremely efficiently throughout the rev range. Even with its super-beneficial electric starter this model is still the lightest 450 engine on the MX market.

CHASSIS

The KTM 450 SX delivers metal twisting torque and requires a strong frame to cope with its immense power. For 2019, a new lightweight, high-tech steel frame was developed to further improve the power-weight-ratio, without compromising strength and durability. It features refined flex characteristics that ensure the bike soaks up those big hits while also maintaining excellent agility and high-speed stability. The chassis also features additional innovative elements, like "no dirt" foot pegs and new brackets for mounting an optional composite skid plate. Overall, every element of the chassis contributes to an intuitive, high-performance ride like no other.

ERGONOMICS & COMFORT

When it comes to the powerhouse of KTM's SX range, it is imperative that a rider is able to shift his weight quickly and easily to work in unison with the motorcycle. KTM places a great deal of emphasis on creating the optimal ergonomics for high-level performance, making sure the neutral riding position offers the best control. A rider's main interaction with the motorcycle comes through the bodywork, seat, footpegs and handlebars and these crucial contact points play a vital role in balance and control. There is no doubt that the KTM 450 SX-F packs a serious punch and by ensuring the very best high-performance ergonomics, a rider has the confidence and control to use it as it is meant to be.

BODYWORK & GRAPHICS

Unloading a KTM 450 SX at the track is an immediate declaration of your race winning intentions. With the help of KTM factory riders, as well as KTM R&D and Kiska Design, they were able to further refine the bodywork of the entire SX range, achieving complete harmony between rider and bike, further enhancing this powerhouse's dominant appeal. Their main focus when designing the SX range was to provide contact points that allow maximum freedom of movement and improved overall handling. Brute strength at the lowest possible weight is what this bike is all about and can be seen in the intelligent I-beam design on the front and rear fenders, which guarantee maximum stability at no extra weight. The new aggressive-looking graphics were not only a necessary change, but were designed to send a clear message to the competition that this is not a bike that should be taken lightly.

SOFTWARE & ELECTRONICS

With the KTM 450 SX-F producing a dirt ripping 63hp, every effort has been made to ensure the power is delivered in a controlled manner. Additional to the considerable mechanical effort to ensure usable delivery of the power is an electronics package with the ability to refine it to perfection. Activated by a multifunctional handlebar map switch, a rider has access to important features like traction control, launch control and even alternative power curves. Many hours were spent in development, creating mind-blowing power and torque. This made electronics a necessary innovation that ensures power gets to the ground in the most effective way. A proven electric starter gets this dirt-shredder fired up, ensuring the ultimate motocross experience starts with the simple push of a button.
