THE NEW KTM SX RANGE IS OUT NOW!

After the race is before the race and when it comes to competing in the most prestigious championships around the world, this mantra is an important one to live by. KTM’s desire to win in AMA Supercross and the FIM Motocross World Championship continues to be demonstrated with outstanding performances in each series thanks to KTM’s focus on creating the sharpest weapons for the toughest battles. This READY TO RACE mindset and development in the most challenging arenas is translated directly into our serial production models.

Following on from last year’s ground-breaking introduction of a new KTM SX generation, for model year 2020 the 2-stroke KTM 125 SX, KTM 150 SX and KTM 250 SX, and the 4-stroke KTM 250 SX-F, KTM 350 SX-F and KTM 450 SX-F have received performance enhancing engine updates to ensure they remain at the fore and as battle-ready as ever. These detailed refinements, that have been developed with KTM´s test riders in Europe and the USA along with factory racers around the globe, complement the high-quality serial components that the KTM SX range already boasts.

New graphics and colors give the range a fresh look for the new season, while an E-starter and a map select switch with integrated traction control and launch control on 4-stroke machines, premium brakes supplied by Brembo, No-Dirt footpegs are fitted as standard to KTM’s class-leading line-up. High quality exhaust systems, plastics and seats join the reworked WP XACT suspension with the proven AER technology, which offers enhanced handling for model year 2020.

Designed by the very same engineers that are responsible for the bikes raced by the likes of Jeffrey Herlings, Antonio Cairoli and Cooper Webb, the KTM sportminicycle line-up continues to set the benchmark in out-of-the-crate performance for junior riders. For MY2020 the KTM 50 SX, KTM 65 SX and KTM 85 SX have a new look and feature the WP XACT suspension for precise handling and stability in the toughest motocross terrain.

All of the junior models boast premium components such as high-quality Formula brakes, a high-strength steel frame, ergonomically designed bodywork and high-performance engines. For model year 2020 the KTM 65 SX has a reworked ignition curve for improved performance, while the carburetor has been optimized for better power delivery. Its bigger brother, the KTM 85 SX, has a new transmission drive shaft fixing for safer sprocket fixation. The KTM 85 SX also has a reworked muffler with improved packing wool, which saves weight.

In addition, the KTM SX-E 5 will join the sportminicycles as another competitive option for junior riders. Based on the KTM 50 SX with its high-end chassis, but powered by an electric motor, the KTM SX-E 5 is easy to ride, has zero emissions, low noise and requires minimal maintenance – giving riders more options for places to ride, whilst being easy to use. The height of the bike is also completely adjustable, and it is aimed at riders aged from 4 to 10 years old, making it an exciting new model in the KTM line-up. The KTM SX-E 5 will be launched this summer.

“To be the consistent performer at any level of racing, you have to continue to progress in development. The work never stops – whether that’s here in Mattighofen, or with our engineers in the USA. The KTM SX range model year 2020 has received a number of updates to complement last year’s groundbreaking new generation models, and we can see that our continued efforts in development are paying off – our athletes both in Supercross and Motocross have enjoyed some fantastic results so far this season. Utilizing the same R&D team as their bigger brothers, the KTM sportminicycle models remain at the very forefront of junior racing competition with detailed refinements for MY2020. In addition, we are excited for the highly anticipated launch of the all-new KTM SX-E 5 electric minicycle, which will arrive this summer,” said KTM´s Senior Product Manager Offroad, Joachim Sauer.

 

 

2020 KTM 450 SX-F Totalmotorcycle.com Features and Benefits

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 new KTM 450 EXC-F’s fuel-injected SOHC powerhouse is the lightest 450 single-cylinder offroad racing engine on the market. It is extremely compact, with ground-breaking torque and power across the entire rev range thanks to a newly developed cylinder head and updated electronic fuel injection system. In combination with a reworked engine case, KTM has reduced its weight to only 29.2 kg, making it the most compact, lightest and most competitive powerplant in its class.

 

CHASSIS
The KTM 450 SX-F delivers metal twisting torque and requires 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, contribute 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’s dirt-ripping engine performance, every effort has been made to ensure the power is delivered in a controllable manner. As well as the considerable mechanical effort to produce usable power, there is also an electronics package with the ability to refine it to perfection. Activated by a multi-functional 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, 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.
