ENGINE & EXHAUST
4-strokes have taken motocross to unthinkable new extremes in a playground where KTM is the dominant force. Lighter and more compact than ever thought possible, these well-balanced engineering masterpieces deliver class-leading power in the most dynamic way. Straight from the showroom floor, KTM 4-strokes offer READY TO RACE performance of the highest caliber.
The KTM 450 SX-F delivers metal twisting torque and demands a strong frame to handle its immense power and speed. A new lightweight, high-tech steel frame was developed for the 2019 range and the proven formula carries over to the 2020 model. 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 brackets for mounting an optional composite skid plate. For 2020, the suspension features improved damping characteristics. The reworked settings offer a slightly softer, more comfortable feel that, together with the dynamic, performance-oriented 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 riders are able to shift their weight quickly and easily to counter the forces acting against them. 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 all these 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-F at the track is an immediate declaration of your race winning intentions. Using feedback from KTM factory riders, the bodywork of the entire SX range achieves complete harmony between bike and rider. The main focus is 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 details of the intelligent I-beam design on the front and rear fenders, which guarantee maximum stability at no extra weight.
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 controllable manner. Additional to the considerable mechanical effort to produce usable power, is an electronics package with the ability to refine it to perfection. Activated by a multifunctional handlebar map switch, the 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, making 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.
