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 150 SX Totalmotorcycle.com Features and Benefits
ENGINE & EXHAUST
KTM 2-strokes have been tearing up MX tracks for decades and are undoubtedly the fastest on the track today. Thanks to years of ongoing development, these engines are the benchmark in performance and technology, with the perfect combination of power, weight and control. For 2020, small, but important refinements have been made, resulting in improved power delivery and reliability and through its melodic high-RPM screams, KTM150 SX continues to deliver thrilling high-performance harmonics.
The KTM 150 SX is just made to be ridden aggressively and features a chassis that delivers on the rider’s demanding expectations. The lightweight, high-tech steel frame is designed to respond instantly to rider input and provide accurate rider feedback. The flex characteristics help the bike to soak up those big hits while also delivering excellent agility and high-speed stability. For 2020, the suspension features improved damping characteristics. The reworked settings offer a slightly softer, more comfortable feel that, together with the frame, allows the rider to be 100% in charge of the ride.
ERGONOMICS & COMFORT
When it comes to attacking the track, chasing faster times with every lap, there is no better weapon than the KTM 150 SX. Its performance-inspired design allows the rider to shift his weight quickly and easily, working in perfect harmony with the motorcycle. KTM has focused extensively on creating bodywork and ergonomics that are shaped for high-level performance, ensuring a riding position that offers the best control. A rider’s main interaction with the bike is through the bodywork, footpegs and handlebars. No compromises were made in these important areas and only the best quality products and designs can be seen on all SX models. KTM produces incredibly fast motorcycles and every effort goes into making sure the rider has the ability to confidently control it.
BODYWORK & GRAPHICS
Those who ride a KTM 150 SX thrive on the extra power it delivers, while still having the dynamic agility and feel that a 125 cc offers. These riders are always pushing themselves and their machines to the limit and need the freedom of movement to position the bike where they want it on the track. With input from KTM factory riders, KTM R&D as well as Kiska Design, the bodywork on the entire SX range achieves perfect harmony between rider and bike, providing the maneuverability the rider expects and the control they need. The bodywork also contains intelligent design elements, like the I-beam structure on the front and rear fenders, which guarantee maximum stability without adding any extra weight.
SOFTWARE & ELECTRONICS
Absolute performance purity is the name of the game when it comes to the KTM 150 SX. Undiluted 2-stroke simplicity, with an hour meter to keep a check on how long you’ve been shredding and an optional rev counter to assist with perfect setup.
