Overview

2020 KTM 250 SX

EXHILARATING POWER AND CONTROL

Featuring a high-performance 2-stroke engine fitted within a state-of-the-art chassis, this powerhouse is undoubtedly the fastest 250 cc 2-stroke on track. This proven race weapon is the right choice for those who thrive on that glorious 2-stroke sound while smashing out one hot lap after the next.

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. Through melodic high-RPM screams, KTM 2-strokes continue to deliver thrilling high-performance harmonics.

CHASSIS

The chassis forms an integral part of the feeling a rider has with his bike. The chassis on the KTM 250 SX is designed to provide accurate feedback between the track and the rider, while also reducing the harshness of typical motocross terrain. The high-tech steel frame is made from chrome-moly and features optimized flex characteristics that soak up those big hits while also delivering excellent agility and high-speed stability. In 2019, the engine was raised in the frame by 1° around the swing arm pivot, improving the handling and the grip of the front wheel and remains the same for 2020. 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, ensure that the KTM 250 SX remains one of the most thrilling rides out there.

ERGONOMICS & COMFORT

A rider's ability to work in unison with his bike depends on how quickly and effectively he can shift his weight around the motorcycle. KTM focused extensively on creating bodywork and ergonomics that allow for the highest levels of performance. This ensures that the natural riding position offers the best possible control and, through various handlebar positions, can also be adjusted to suit every rider and condition. A rider's main connection to the motorcycle comes through the seat, footpegs and handlebars and these three touch points play a vital role in maintaining balance and control. The rider is always looking for a fast and competitive motorcycle with a great feeling of controlled agility. The 2020 KTM 250 SX, like the entire SX range, ticks all the right boxes, especially when it comes to race-ready ergonomics.

SOFTWARE & ELECTRONICS

Absolute performance purity is the name of the game when it comes to the KTM 250 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.

Cooling

Highly Effective Cooling

Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 250 SX features radiators which are positioned for a lower 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 serve not only 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

For Sound of Power

When it comes to power delivery and performance, the exhaust plays a key role and packs a punch that is hard to beat. In addition, its narrow shape provides slimmer ergonomics while still operating safely within the noise limits for racing.

Chassis

Control at the Core 

The frame is professionally crafted from hydroformed chromium molybdenum steel tubes that are robot welded, ensuring the highest levels of consistent quality. The stiffness has been precisely tailored for the most dynamic handling, and works in perfect harmony with the suspension to provide nimble agility without losing high-speed stability. The frame also features "no dirt" footpegs, which have a simple but effective self-cleaning system that ensures the footpegs return to their original position, providing complete control in all conditions. All SX frames feature the same highly durable powder coating as the KTM Factory machines and come with standard frame protectors. The subframe is made from lightweight aluminum, providing rear fender stability and strong support for the rider at little extra weight.

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.
