Overview

2020 KTM 450 SX-F

POWER SUPREMACY

It features an extremely compact, single overhead camshaft cylinder head and together with the efficient electronic fuel injection, it pushes out an unrivalled 63hp in the most effective way possible. The KTM 450 SX-F is simply the fastest Motocross bike out on the track.

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.

CHASSIS

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.

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.

Unrivalled Power

The 450cc engine is the ultimate powerhouse when it comes to KTM's competitive motocross range. Its compact, lightweight design features a single overhead camshaft cylinder head, fueled by the latest electronic injection system. 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 cc engine on the MX market.

Cooling

Effective Heat Control

Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 450 SX-F features radiators which are positioned for a lower the center of gravity. Their design matches the shrouds perfectly and offers a great slim feel to the ergonomics. By using CFD technology (computational fluid dynamics) together with a clever coolant circuit routing, the innovative system ensures the optimum engine temperature for the highest performance, no matter what the conditions. The radiators also feature special protectors that don't only serve as protection from flying rocks and debris but also as a brace that disperses energy around the radiators in the event of an impact.

 

Exhaust

Tuned for Power

When it comes to power delivery and performance, the exhaust on all 4-stroke models plays a key role and packs a punch that is hard to beat. It features a model specific header pipe with an advanced resonator called FDH (Flow Design Header), which is a small chamber around the pipe. The design allows the exhaust to be disassembled without removing the shock absorber and also provides better access to the shock. The aluminum sleeve, end cap and internal design of the silencer allows for slimmer ergonomics, making the bike feel narrower, without compromise to regulatory noise limits.

Chassis

Superior Core Stability

As with the entire KTM SX range, the frame on the KTM 450 SX-F is professionally crafted from hydro-formed chromium molybdenum steel tubes that are robot welded to ensure the highest levels of consistent quality. The precisely calculated stiffness of the frame delivers responsive handling and works perfectly with the suspension to provide excellent agility and high-speed stability. All 2020 KTM SX frames feature a highly durable powder coating and come with standard frame protectors. The subframe is made from lightweight aluminum and provides great feeling for the rider, as well as easy movement across the seat.

Wheels

KTM uses lightweight, CNC-machined hubs and high-end Excel rims on all SX models, guaranteeing maximum stability and minimum weight. The aluminum spoke nipples feature a design that conveniently reduces the frequency with which the spokes need to be tightened. The wheels are fitted with the latest DUNLOP Geomax MX 3S tires, delivering maximum grip and stability, effectively transferring all the power to the ground.

Brakes

Highly Effective Braking

High-tech BREMBO brakes have always been standard equipment on all KTM motocross bikes. Combined with lightweight wave discs, the renowned system provides the highest level of braking efficiency, enabling you to out-brake the competition.
