RELEASE THE RUCKUS

The 2023 KTM 250 SX takes that to an all-new, gnarlier level. Thanks to a swathe of cutting-edge advancements across the board, this 2-stoke legend has stepped up, and even further out of reach of the competition.

ELECTRIC START

Picture this – you’re 7 laps into an absolute ripper of a race. You miss your line and end up stalling in a deep rut. But you don’t sweat it. All you do is press the starter button and you blast off again to take the final flag. This is the reality on the 2023 KTM 250 SX. Thanks to a 12.8V 2 Ah lithium ion battery placed under the rider’s seat, a new high-quality stator & pick-up and super robust design, the only thing you’ll be kicking is ass.

EASY SUSPENSION ADJUSTMENT

Get dialed in! The 2023 KTM SX range boasts totally tool-free suspension setup at both ends. Thanks to an all-new shock absorber design featuring hand-adjustable dual compression control, it allows riders to adjust high and low speed settings in a matter of seconds. On the front end, the forks are also easily adjusted thanks to a single air pressure preload valve, as well as through easy access click adjusters for compression and rebound.

ELECTRONIC FUEL INJECTION

Pre-mix gets a remix across the 2-stroke KTM SC range, with electronic fuel injection setting the standard. Now there’s no more fiddly jetting setup pre-race, and thanks to the all-new Keihin EFI and reed valve case design, you can be guaranteed of laying down optimal power at any altitude, all of the time.

EFI & POWER VALVE

With EFI comes great rideability. Along with the electronic fuel injection, a new Power Valve has also been fitted to the KTM 250 SX, allowing for more usable power through the rev range. Smoother power means better traction. Better traction means holeshot heaven!

PERFORMANCE

The KTM 250 SX has always represented the very best of unsurpassed power and lightweight construction. The simplicity and low maintenance cost of the 2-stroke motor have made it a favourite amongst motocross riders for generations. For 2023, the KTM 250 SX enters the race paddock with 53 hp, and an overall engine weight of only 23.9kg, setting the benchmark in the highly competitive 250 cc class.

SELECTABLE MAPS

The 2023 KTM 250 SX features a map select switch allowing the racer switch between 2 engine maps. Map 1 provides a linear, predictable power delivery, while Map 2 gives it the full beans with crisp, explosive power output.

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.

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.
